Light rainfall of below 50 mm is expected over the coastal parts of Adan Yabaal, Cadale, and Balcad districts in Middle Shabelle region, as well as Banadir, coastal parts of Jilib district in Middle Juba region, Jamame, Kismayo, and Badhaadhe districts, and the border areas between Afmadow and Kismayo districts in Lower Juba region. Similarly light rains are also anticipated over areas bordering Bur Hakaba district in Bay region and Qoryooley district in Lower Shabelle region. Dry conditions are expected to prevail over the rest of the country in the upcoming week. Similar dry conditions are also expected over the Ethiopian Highlands. Temperature Forecast The current forecast indicates the likelihood of high temperatures ranging from 30 ℃ to 35 ℃ over extensive areas in the south, central and northeastern parts of the country. Milder temperatures ranging between 20 ℃ and 25 ℃ are anticipated over some areas in the following regions: Awdal, Woqooyi Galbeed, Togdheer and Sanaag regions and inland parts of Bari region. Moderate temperatures of 25℃ to 30 ℃ will prevail over the rest of the country.

Between the 12th and 15th of November 2023, approximately 24,318 buildings, 562 km of roads and 14,697 Hectares of farms in Belet Weyne were flooded, as depicted on the map. The flood extents were identified through a comprehensive analysis, incorporating data from a modified Global Flood Model (GFM) based on Sentinel-1 image of November 14, 2023, visual interpretation of UNOSAT Beletweyne city extent data of November 12, 2023, and Sentinel-2 image of November 15, 2023. This inundation had a notable impact on the region, affecting 54% of buildings, 6% of the main road distance, and 41% of agricultural cropland. The data derived from this analysis offers a detailed overview of the extent and consequences of the flooding, facilitating a more informed understanding of the situation for effective response and mitigation efforts.

In the next one-week, heavy rainfall is expected over the coastal parts of Galmudug; moderate to heavy rainfall is likely over Gedo, parts of Bakool, Hiran, Lower Juba, and Middle Juba regions, and dry conditions with chances of isolated light rainfall in anticipated over Somaliland and Puntland (Map 1). The three -days forecast (Map 1) shows that much of the forecast rains over Mudug region are likely to be received between 8th and 10th November 2023. The spatio-temperal variation of the forecast rainfall (Map 1) is described below: • Heavy rainfall of between 100 mm and 150 mm is expected over several areas in the coastal parts of Galmudug state and in isolated areas in Jilib district in Middle Juba region, Garbaharey and Belet Xaawo districts in Gedo region, and Hudur and Tayeeglow districts in Bakool. The rains over the coastal parts of Galmudug are likely to be intense (more than 150 mm) with the localized storms over Ceel Dheer and Xarardheere districts cumulating to over 200 mm. • Moderate rainfall of between 50 mm and 100 mm is forecast over several areas in Gedo region, Ceel Dheer and Ceel Buur districts in Galgadudd region, Xarardheere, Hobyo and Jaribaan districts in Mudug region, Bulo Burte district in Hiraan region, and Hudur and Tayeeglow districts in Bakool region. Towards the south, rainfall of similar amount is expected over several areas in Qansax Dheere and Dinsoor districts in Bay region, Jilib and Saakow districts in Middle Juba region, Jamaame district, southern parts of Badhaadhe district, western parts of Afmadow district in Lower Juba region. • Light to rainfall of below 50 mm is expected over several areas in Lower Shabelle and Middle Shabelle regions, Kismaayo district and central and eastern parts of Afmadow districts in Lower Juba region, central parts of Middle Juba region including Bualle district. Similar rains are also likely over Bur Hakaba abd Baydhaba districts in Bay region, Rab Dhuure, Waajid and Ceel Barde districts in Bakool region, BeletWeyne and Jalalaqsi districts in Hiraan region. In the central parts of country, the areas that are expected to receive rains if similar intensities include: Cabudwaaq, Dhuusamareeb and Cadaado districts in Galgaduud region and Galdogob district in Mudug region. • Dry conditions are expected over expansive areas in Somaliland and Puntland, except Gaalkacyo district in Mudug region where isolated light rainfall is expected.

Juba River Moderate to heavy rains received for about two weeks have generated run off that have caused the water levels along the entire Juba River to overflow their riverbanks causing devastating floods which have led to damage to crop lands and road infrastructure rendering them impassable and cutting off access in to and out of towns and other human settlements. Following heavy rains (125.0 mm) recorded yesterday 19th November 2023, the bridge at Luuq has been reportedly overtopped and is at risk of being swept away. The rains over Bardheere have been particularly intense with 108 mm, 35 mm, 96 mm and 58 mm of rain having been observed on 16th, 17th, 19th and 20th November 2023, respectively leading to sweeping away of Budubo bridge. Heavy rains have also been received downstream at Bualle with 71.0 mm being recorded yesterday, 19th November 2023. The light to moderate rainfall forecast over Juba River catchment in Ethiopian Highlands and within the Somalia border in Luuq district of Gedo region will generate runoff of less volume compared to previous week. However, the runoff from the previous moderate to heavy rains and ongoing light to moderate rains will sustain the river overflows and flooding at Dollow and Luuq. Run off from both ongoing and forecast moderate to heavy rains over the Juba River downstream catchment at Bardheere district in Gedo region and parts of Middle Juba region will generate enough runoff leading to increased river overflows and flooding at Bardheere, Saakow, Bualle and Jilib districts. There is therefore SUSTAINED FLOODING along the entire Juba River with INCREASING MAGNITUDE at both Bardheere and downstream at Saakow, Bualle and Jilib. The activated response plans should therefore be sustained along the upper stretch and upscaled downstream at Bardheere, Saakow, Bualle and Jilib. Shabelle River Water levels along the Shabelle River have been steadily increasing in the last three weeks. The river reached bankful level (8.30m) at Belet Weyne on Saturday 11th November 2023. The subsequent riverbank overflow led to massive floods in Belet Weyne town and the surrounding areas leading to damage to buildings, crop lands and rendering the passage into and out of town impassable due to bridge overflows. Based on timely advisories from SWALIM, SoDMA/MoHADM and other partners, the population was safely evacuated to designated higher grounds by the time the floods started. Moderate to heavy rains have been reported along the Shabelle River catchment with 70 mm, 31.8 mm and 29 mm received yesterday, 19th November 2023, at Bulo Burte, Jowhar and Balcad, respectively. The flow of the flood wave downstream coupled with moderate to heavy rains have led to river level rise at Bulo Burte to 32 cm above high flood risk level and only 48 cm below bankful. At Jowhar the level is only 10 cm below moderate risk level and 60 cm to bankful. Even if the flood wave is expected to flow downstream beyond Balcad in the coming days, floods have already been observed as a result of river breakages and flash floods. The light to moderate rainfall forecast over Shabelle River catchment in Ethiopian Highlands and within Hiran region in Somalia will generate runoff of less volume compared to previous week. However, the runoff from the previous moderate to heavy rains and ongoing light to moderate rains will sustain the river overflows and flooding at Belet Weyne and steady river level rise downstream at Bulo Burte, Jalalaqsi, Jowhar and Balcad. There is therefore SUSTAINED FLOODING at Belet Weyne and its environs and HIGH RISK OF FLOODING at Bulo Burte and its environs and PROJECTED HIGH RISK at Jowhar and its environs. The activated response plans should therefore be sustained at Belet Weyne town and the surrounding areas. The evacuation plans should be activated and sustained at Bulo Burte and surrounding areas, while it should be placed on standby at Jowhar and surrounding areas.

Utilizing the flood extent analysis conducted by UNOSAT on November 7th, 2023, it is evident that the onset of El Niño in the Horn of Africa has caused the flooding of 6,494 hectares of land in Luuq District. As per OSM data, this has resulted in the submersion of 316 buildings and 29 kilometers of roads. Additionally, 3,013 hectares of agricultural land, as per SWALIM agrimask, were submerged. This data emphasizes the immediate and significant repercussions of the ongoing El Niño event on the region.

By 20th of November 2023, approximately 43,455 buildings; 968 Km of road and 28,418 Hectares of farms in Belet Weyne were flooded, as depicted on the map. The flood extents were identified through a comprehensive analysis, incorporating data from a modified Global Flood Model (GFM) based on Sentinel-1 image of November 20, 2023, visual interpretation of UNOSAT Beletweyne city extent data of November 16, 2023, and Sentinel-2 image of November 20, 2023. This inundation had a notable impact on the region. The data derived from this analysis offers a detailed overview of the extent and consequences of the flooding, facilitating a more informed understanding of the situation for effective response and mitigation efforts.

Light Rainfall expected over the Central Parts of Hargeisa and Gebiley Districts, with Dry Conditions Beyond the Eastern and Northern Parts of Baki and Borama Districts Weather Review for the Period 1st and 7th November 2023 During the period under review, rainfall of at least 1 mm was recorded in Thirteen (13) stations (Graph 1), down from twenty (20) stations the previous week. The following eleven (11) stations, down from six (6) stations, observed cumulative rainfall equal to or greater than 30 mm: Caynabo (79 mm), Gumburaha (78 mm), Laas Dawaco (74 mm), Sheikh (67.5 mm), Yagori (66 mm), Balli Dhiig (60 mm), Salaxley (46 mm), Garadag (43 mm), Geerisa (40 mm), Bolohar (36 mm), and Lughaye (32 mm). The best temporal distribution of rainfall was realized at Caynabo (79 mm) where three rainy days were recorded. The most intense rains were those received in a single day over Yagori (66 mm), Geerisa (40 mm), Bolohar (36 mm), Lughaye (32 mm), Erigavo (26.5 mm), and Burao (17 mm). Weather Forecast for the Period 10th to 16th November 2023 Rainfall Forecast Light rainfall of between 30 mm and 40 mm is expected over the western parts of Hargeisa district and central parts of Gebiley district. Light rainfall of between 10 mm and 30 mm is likely over Baki district, eastern parts of Hargeisa district, southern and northern parts of Gebiley district and southern parts of Borama. Dry conditions with chances of light rainfall of below 10 mm are likely to prevail over the eastern parts of the project area. Temperature Forecast Milder temperatures of between 20 ℃ and 25 ℃ are likely over Borama and Gebiley districts, southern parts of Baki district, and most parts of Hargeisa district except over the northern where relatively higher temperatures 25℃ and 30 ℃. will prevail. High temperatures of between 30 ℃ and 35 ℃ are also likely over Lughaye and northern parts of Baki districts.

According to the coming week’s weather forecast, substantial rainfall is expected over Middle Shabelle region and the coastal areas of Galgaduud region. Additionally, the forecast indicates a range from moderate to heavy rainfall across Lower Juba, Middle Juba, Gedo, Lower Shabelle, and Bay regions. Dry conditions are anticipated throughout the rest of the country, with isolated chances of light rainfall over Bakool, Bari, Sanaag, and Woqooyi Galbeed regions. For the spatial and temporal distribution of the forecasted rainfall, refer to Map 1. Heavy rainfall of between 100 mm and 150 mm is expected over coastal areas of Cadale, Balcad and Adan Yabaal districts in Middle Shabelle region. Similarly heavy rainfall is likely over Ceel Dheer district in Galgaduud region. Moderate rainfall of between 50 mm and 100 mm is forecast over inland parts of Cadale, Balcad and Adan Yabaal districts in Middle Shabelle region and Kismayo district in Lower Juba region. Light rainfall of below 50 mm is expected over Waajid district in Bakool, several areas in Lower Juba region, Middle Juba, Gedo, Bay, and Lower Shabelle regions. Similar conditions are likely in Caluula and Iskushuban districts in Bari region, and coastal parts of both Laasqoray and Berbera districts. Dry conditions are expected over areas around Saakow district in Middle Juba, Garbahaarey and Luuq districts in Gedo region, scattered areas of Bay region, extensive parts of Bakool, Hiraan, Galgaduud regions. Similar dry weather patterns are also expected in extensive parts of the entire northern regions of the country. Temperature Forecast: The current forecast indicates the likelihood of high temperatures ranging from 35°C to 45°C over extensive parts of the south, central and northeastern parts of the country. Milder temperatures ranging between 20°C and 25°C are anticipated over Awdal, Woqooyi Galbeed, Togdheer and Sanaag regions and Inland parts of Bari region.

Juba River For more than a week now, run off from moderate to heavy rains have caused the water levels along the entire Juba River to overflow their riverbanks causing devastating floods which have led to damage to crop lands and road infrastructure rendering them impassable and cutting off access in to and out of towns and other human settlements. The rains over Bardheere have been particularly intense with up to 126 mm having been observed in the last two days. The 46-year old steel bridge at Bardheere was overtopped and eventually gave in to the floods and collapsed. The runoff from both ongoing and forecast moderate to heavy rains over the Juba River catchment will sustain the river overflows and flooding at Dollow and Luuq and worsen the flooding at Bardheere and downstream reaches. There is therefore SUSTAINED FLOODING along the entire Juba River with INCREASING MAGNITUDE at both Bardheere and downstream at Saakow and Bualle. The activated evacuation plans should therefore be sustained and along the entire stretch and upscaled at Bardheere and downstream. Shabelle River For about two weeks now, the water levels along the Shabelle River have been steadily increasing. On Saturday 11th Nov, arrival of the earlier projected floodwave from the Ethioipian Higlands led to a sharp rise in the water level at Beletweyne to bankful level (8.30 m). The subsequent riverbank overflow led to massive floods covering up top 90 % of the town only sparing the few elevated areas. The flow over the main bridge cut the town into two parts. Based on timely advisories from SWALIM, SoDMA/MoHADM and other partners, the population had been safely evacuated to designated higher grounds by the time the floods started. Subsequent voluminous inflows have led to further spread of the floodwaters as reported today. Floods have also been observed at Balcad as a result of river breakages. The river level at Bulo Burte is steadily rising, and now only 36 cm below the high flood risk level and 126 cm below bankful. At Jowhar the level is only 65 cm below moderate risk level. The runoff from the ongoing and forecast moderate rains over the Shabelle River catchment upstream in Ethiopia and near the Somalia border will sustain the current bankful water levels at Beletweyne. Additionally, voluminous water measuring up to 9 km can be identified on the current satellite images upstream of Beletweyne in Ethiopia. There is a high likelihood that the arrival of this flood wave will lead to further significant river level rise and flooding at Beletweyne in the coming days. The run off from the forecast very heavy rains over the Shabelle River catchment on the eastern parts of Bulo Burte in the coming week will add to the downstream flow of the flood wave currently at from Beletwyene leading to rise in river levels at Bulo Burte, Jalalaqsi and Jowhar to high flood risk levels then bankful levels. Flash floods are also expected in Bulo Burti and surrounding areas following the very heavy rainfall expected over the next 3 days. There is therefore ONGOING FLOODING WITH INCREASING MAGNITUDE at BeletWeyne and its environs and ONGOING FLOODING WITH MODERATE MAGNITUDE at Balcad and its environs and HIGH RISK OF FLOODING at Bulo Burte and its environs and PROJECTED HIGH RISK at Jowhar and its environs. The activated evacuation plans should therefore be sustained at Beletweyne town and the surrounding areas. The evacuation plans should be activated at Bulo Burte and surrounding areas. The evacuation plans should be placed on standby at Jowhar and surrounding areas.

Extremely heavy rainfall is expected over Gedo, Lower Juba, Hiran, and Togdheer regions; moderate to heavy rainfall is anticipated over several other parts except for Bari region and coastal areas of the country where light rains is expected. A three -days forecast shows that much of these rains are likely to be received between 1st and 3rd November 2023. The spatio-temperal variation of the forecast rainfall (Map 1) is described below: • Extremely heavy rainfall of between 150 mm and 200 mm is expected over several areas in Gedo region, Afmadow district in Lower Juba region, southern parts of Saakow district in Middle Juba region, Beletweyne and Bulo Burte districts in Hiraan region, southern parts of Togdheer region, and Las Anod. The rains particularly over Gedo region, northern parts of Afmadow district in Lower Juba region, southern parts of Beletweyne district and northern parts of Bulo Burte district in Hiraan region, and Buuhodle district and southern parts of Burco district in Togdheer region are likely to be very intense leading up more than 200 mm. Rains of comparable amounts is also forecast over the middle and upper catchments of both Juba and Shabelle Rivers in Ethiopian Highlands. • Moderate to heavy rainfall of between 50 mm and 100 mm is forecast over most areas in Bakool, Bay, Saakow and Jilib districts in Middle Juba region, Cabudwaaq district in Galgaduud region, Galdogob district, eastern and southern parts of Gaalkayo district and northern parts of Hobyo district in Mudug region, and isolated areas in Lower Juba region. Towards the north, rainfall of similar amounts is also anticipated over several areas in Togdheer and Sool regions, Hargeisa district in Woqooyi Galbeed region, Ceel Afweyn district and southern parts of Ceerigaabo district in Sanaag region, Burtinle district in Nugaal region, and isolated areas in Bari region. • Light to rainfall of below 50 mm is expected over several areas in Lower Shabelle and Middle Shabelle regions, central parts of Lower Juba region, Bualle district in middle Juba region, and Jalalaqsi district in Hiraan region. Such rains are also expected over the central parts of the country including Galgaduud region, Xarardheere district and southern parts of Hobyo district in Mudug region, Eyl and Garowe districts in Nugaal region. In the north, rains of such amounts are expected over several areas in Bari region, Laasqoray district and eastern parts of Ceerigaabo district in Sanaag region, Gebiley district and central parts of Berbera district in Woqooyi Galbeed, Baki and Lughaye districts in Awdal region. • Dry conditions are expected over the coastal areas in both Iskushuban and Caluula districts in Bari region and the southern parts of Borama district and western parts of Zeylac district in Awdal region.

Vey light rainfall expected over the Berbera district in the northeastern parts of the project area, with dry conditions prevailing in the other areas. Weather Review for the Period 14th to 20th November 2023 During the period under review, rainfall of at least 1 mm was observed in thirty-four (34) stations, as illustrated in Graph 1. This marks an increase from the previous week's thirteen (13) stations with recorded rainfall. Twenty stations (20) reported cumulative rainfall exceeding 30 mm. The specific stations, their respective rainfall totals and rainy days are as follows: Laas Dawaco (122 mm in 2 days), Bulohar (110 mm in 2 days), Gacan_libah (97 mm in 3 days), Malawle (75 mm in 2 days), Gargara (61 mm in 1 days), Baligubadle (59 mm in 2 days), Gerisa (58.5 mm in 2 days), Berbera (56 mm in 2 days), Hargeisa (55 mm in 2 days), Salaxley (53 mm in 2 days), Xeego (50 mm in 2 days), Garbodadar (47.5 mm in 1 days), Lughaye (46 mm in 3 days), Sayla (45 mm in 1 days), Dhubato (43.5 mm in 2 days), Cadaadley (35 mm in 1 days), Dararweyne (34.5 mm in 3 days), Geedeble (34 mm in 1 days), Zaila (34 mm in 2 days), and Taysa (33 mm in 2 days). Having been recorded on one of the days of the week under review, the rains over Bulohar (70 mm), Laas_Dawaco (68 mm), Gargara (61 mm) and Gacan_libah (56 mm) were the most intense. The best three-days rainfall distribution was achieved over Gacan_libah, (97 mm), Lughaye (46 mm) and Dararweyne (34.5 mm). Weather Forecast for the Period 22nd to 28th November 2023 Rainfall Forecast: The weather forecast indicates very light rainfall of between 2 and 5 mm over the northeastern parts of the project area. These areas include western parts of Berbera, Banmadar and Cabdi Geeddi in the eastern part of Baki district; Ceel Lay Heelay, Bildhaaley, Bodale and Daradawanley in the northern part of Hargeisa district. Dry conditions with chances of rainfall less than 2 mm will prevail over the rest of the project areas. Temperature Forecast: Milder temperature of 20 ℃ to 25 ℃ is expected over some areas in the south of Gebiley district and in the southwest of Hargeisa district. Comparatively higher temperature of between 30 ℃ and 35 ℃ is anticipated in Lughaye district and some areas in the northeastern parts of Baki district. Moderate temperatures of between 25 ℃ to 30 ℃ are expected to prevail over the rest of the project areas.

Somalia grapples with the looming impacts of an impending El Niño, exacerbating the ongoing climate change challenges. Recurrent riverine and flash floods, particularly in urban centers are of significant concern. Urgent action is needed to prepare for and mitigate the forthcoming El Niño floods, aiming to safeguard lives and mitigate economic losses. Key to this strategy is proactive flood management, involving timely evacuations to higher ground. Identifying suitable elevated areas serves a dual purpose, ensuring safety and facilitating aid delivery. In this regard a rigorous GIS & RS methodology by SWALIM considered nine crucial factors, such as historical flood extent, elevation, slope, topographic wetness index, drainage density, strategic boreholes, settlements, land cover, and roads, to isolate higher grounds suitable for evacuation. The resulting maps show safe areas for evacuation in case of flooding, while exercising discretion considering factors like proximity to schools, healthcare facilities, pest prevalence and any other unforeseen factors.

Shabelle River In the last 24 hours, heavy rainfall has been received and recorded (21st October 2023) at Beletweyne (88.2 mm), Mataban (40.0 mm), Bulo Burte (51.0 mm), Mahaday Weyne (20.0 mm), Jalalaqsi (87.0 mm), Jowhar (18.0 mm) and Balcad (23.0 mm). Compared to yesterdays’ measurements, the levels have increased by 1.29 m at Beletweyne, and by 0.12 m at Bulo Burte, while it remained stable at Jowhar. These localized rains also led to flash floods in Beletweyne which affected population, assets, and livestock particularly at the bridge near the ex-livestock market and in Hawo Taako and Kooshin villages. The IDPs are reported to have been safely evacuated to Ceel Jaale. Light rainfall is predicted over the Shabelle catchment within the country in the next 24 hours increasing to moderate cumulative amounts in the coming seven (7) days. Although light rain is forecast over the Shabelle river basin in the Ethiopian highlands today, it is expected to increase to between moderate and heavy rains in the coming seven (7) days. The runoff from previous heavy and forecast light localized rains onto and from seasonal wadis within Hiraan region, together with moderate to heavy rains over the river basin in the Ethiopian highlands, will keep the water levels along Shabelle River rising in the coming seven (7) days. This is therefore an alert to trigger both riverine and flash floods anticipatory actions and to caution communities living at vulnerable areas in Hiraan to be vigilant as the flash flood water stagnates over the saturated surfaces in Beletwyne and the water levels along Shabelle River keep rising. Juba River In the last 24 hours, moderate rainfall has been received and recorded (21st October 2023) at Bardheere (15.0 mm) and Luuq (2.5 mm) with dry conditions over Dollow and Bualle. Compared to yesterdays’ measurements, the levels have increased by 0.5 m at Luuq, increased by 1.04 m at Bardheere, decreased by 0.24 m at Dollow and decreased by 0.17 m at Bualle. The flash floods due to previous localized rains at Luuq have subsided as the water run off to the seasonal wadis and into the Juba River. Light rainfall is predicted over the Juba catchment within the country in the next 24 hours increasing to moderate cumulative amounts in the coming seven (7) days. Although light rain is forecast over the Juba River basin in the Ethiopian highlands today, it is expected to increase to between moderate and heavy rains in the coming seven (7) days. The runoff from previous heavy and forecast light localized rains onto and from seasonal wadis within Gedo region, together with moderate to heavy rains over the river basin in the Ethiopian highlands, will keep the water levels along Juba River rising in the coming seven (7) days. This is therefore an alert to trigger both riverine and flash floods anticipatory actions and to caution communities living at vulnerable areas in Gedo particularly at Luuq and Bardheere to be vigilant as the flash flood water stagnates over the saturated surfaces in Luuq and the water levels along Juba River keep rising.

Moderate to heavy rains expected over inland parts of Central and North Eastern regions particularly around parts of Gedo, Bay, Bakool and Hiraan regions in South Somalia, parts of Mudug and Galgaduud regions in central Somalia and parts of Sool, Sanaag and Bari regions in Northern Somalia. Moderate rainfall of between 50 and 100 mm is forecast over eastern parts of Bakool region particularly Tayeeglow; northern parts of Bay region, and several areas in Hiraan region particularly Belet Weyne, Mahas, and Mataban (Map 1). Rainfall of similar amounts is also likely over Jariiban district in Mudug, Xasbahale district in Nugaal, and Laas Caanon, Xudun, and Taleex districts in Sool. The rains are likely to spread outwards and intensify over Bay, Hiraan, Mudug and Nugaal and prevail beyond the forecast period to cumulative amounts above 100 mm. Other places forecast to receive comparable amounts of rainfall include Garadag, Dhahar, and Buran in Sanaag region, Qardho and Dangoroyo in Bari region, Buuhodle, Balidhiig, and Warabeye in Togdheer region. Light rainfall of less than 50 mm is anticipated across several areas in Somalia. These include Burao, Beer, and Xaaji Saalax in Togheer region; Caynabo, Waridaad, and Yagori in Sool region; Erigavo and El Afweyne in Sanaag region; Ufayn, Ballidhig, and Bandar Beyla districts in Bari region; Garowe and Burtinle districts in Nugaal region; extensive parts of Mudug region; inland areas of Galgaduud region, particularly around Dhuusamarreb, Cadaado, and Cabudwaaq districts; Adan Yabaal and Jowhar in Middle Shabelle region; Wanla Weyne district in Lower Shabelle region; areas around Baidoa and Qansahdere in Bay region; areas around Luuq and Bardheere in Gedo region, as well as areas around Jamame, Kismaayo, and Badhaadhe districts in Lower Juba region. Dry conditions are likely over extensive areas in Awdal region, Woqooyi Galbeed region, western and northern parts of Togdheer region, as well as coastal and western parts of Sanaag region. Similar dry conditions are likely over extensive coastal and northwestern areas of Bari region, Galkayo district and the southern coastal parts of Mudug region, coastal parts of Galgaduud region, and coastal parts of both Lower and Middle Shabelle regions. Dry conditions are also anticipated over Banadir region, southern parts of Bay region, northern and western parts of Gedo region, as well as extensive areas of Lower and Middle Juba.

Significant fluctuations in water levels along the Juba River have been observed. The Juba River surpassed the high-risk thresholds by 10 cm at Luuq on 21st October before decreasing below moderate risk level as of today. Downstream at Bardheere Station, the water level rose from 8.00 m on 21st October to 9.00 m and crossing high-risk threshold (8.20 m) on 22nd October before receding back to 8.00 m today. The downstream flow of the flood wave has led to a 1.1 m rise in the water level at Bualle which currently poses no immediate threat of riverine flooding. Moderate to heavy rains (50 – 100 mm) are expected over the catchment of Juba River within Gedo region and near-border areas with Ethiopia between 23rd and 29th October. The rains over the upper catchment in Ethiopian Highlands may exceed 200 mm posing high risk of riverine flooding towards the end of the forecast period. There is a high risk of flash flooding due to potential localized heavy rains over western parts of Bakool, central parts of Gedo, and Saakow district in Middle Juba region. The water levels along the upper part of Shabelle River are on downward trend. On 21st October, the water level at Beletweyne (6.44 m) was only 6 cm below the moderate flood risk threshold. The levels have since dropped to 6.10 m today. The downstream flow of the flood wave has led to an increase in the water level at Bulo Burte from 4.95 m on 21st October to 5.28 m today. The water level at Jowhar station has also risen during the same time from 3.95 m to 4.28 m. These levels, at both stations, are still below riverine flood risk thresholds. Moderate rainfall (31.5 mm) led to flash floods that affected Badda Cas IDP camp interrupting livelihood activities. Moderate rainfall of about 50 mm is expected over Shabelle River catchment within Hiraan region and near-border areas with Ethiopia. Coupled with the heavy rains recorded one week ago, the heavy rains (more than 150 mm) forecast over the Shabelle River upper catchment in Ethiopian Highlands, are likely to pose high risk of riverine flooding at Beletweyne towards the end of October and beginning of November 2023.

Moderate to heavy rains are expected over Woqooyi Galbeed, Togdheer, Gedo, Bakool and Hiraan regions. Given the general light rainfall activity in the next 7-days, much of the rains are likely to be observed between 28th and 31st October 2023. The spatio-temperal variation of the forecast rainfall is described below: Heavy rainfall of between 100 mm and 150 mm is forecast over several areas in the central parts of Woqooyi Galbeed region and the northern parts of Owdweyne district in Togdheer region, central parts of Gedo region, Bulo Burte district in Hiraan region, and Saakow district in Middle Juba region. Heavy localized rains over these areas are likely to exceed 150 mm with possible cumulative amounts of about 200 mm in Wogooyi Galbeed, northern parts of Owdweyne district in Togdheer region and Bulo Burte in Hiraan region. Very heavy rainfall of above 200 mm is likely over the upper catchments of both Juba and Shabelle Rivers in Ethiopian Highlands. Moderate rainfall of between 50 mm and 100 mm is expected over Baki district in Awdal region, southern parts, Sheikh and Berbera districts in Woqooyi Galbeed region, northern parts of Burco district in Togdheer region, Ceel Afwyene and Ceerigaabo districts in Sanaag region, and Bosasso district in Bari region. Moderate rains are also anticipated over several areas in both Gedo and Bakool regions, Saakow district in Middle Juba region, and Bur Hakaba district in Bay region. In the central parts of the country, rainfall of similar amounts is likely over Gaalkacyo in Mudug region, Cabuudwaaq in Galgaduud region, Bulo Burte district in Hiraan region, and Cadale and Balcad districts in middle Shabelle region. Light rainfall of below 50 mm is likely over the rest of the country except for the following areas where dry conditions are expected to prevail: several areas in Bari, Lower Juba and Middle Shabelle regions, southern parts of Bay region, non-coastal parts of Ceel Dheer district in Galgaduud region, non-coastal parts of Xarardheere district in Mudug region, Garowe district and coastal parts of Eyl district in Nugaal region, and Las Anod district. Temperature Forecast: Elevated temperatures between 35°C and 45°C are likely over Lower Juba, Middle Juba, Lower Shabelle, southern parts of Dinsor and Bur Hakaba districts in Bay region, Jowhar district in Middle Shabelle region, and Sheikh district in Woqooyi Galbeed region. Milder temperatures of between 20°C and 25°C are likely over the highlands in central parts of Sanaag region and northern parts of Bari regions. The rest of the country is expected to observe moderate temperatures between 25°C and 35°C.

Moderate to heavy rainfall of between 50 and 100 mm is anticipated in the northern regions of the country, especially in proximity to Gebiley, Hargeisa, and areas adjacent to the Ethiopian border in Woqooyi Galbeed. Part of Togheer region is expected to experience similar high amount of rainfall especially Sheikh, Odweyn and Buuhoodle districts. In Sanaag region the highest amount of rainfall within the forecast period is expected in Ceel Afweyn and Erigavo districts. Areas around Qardho and Qandala in Bari, as well as Garowe and Burtinle in Nugaal, should anticipate a comparable pattern. Rainfall of comparable amounts is also likely to be observed in many parts of Sool region with chances of heavier storms localized over Xudun, Taleex, and Buuhodle districts. Other parts of the country expected to receive moderate to heavy rainfall include Galkayo and Hobyo in Mudug, Waajid in Bakool, Diinsor in Bay, and Bualle in Middle Juba Region. It is important to point out that rainfall of similarly moderate to heavy amounts is forecast over the Ethiopian highlands. Within Somalia, the heaviest precipitation is projected to occur during the initial three days of the forecast period especially in the northern parts of the country. Light to moderate rainfall is anticipated in Ceel Waaq and Luuq districts in Gedo, Baydhaba in Bay, extensive areas of Bakool, parts of Hiraan particularly Jalalaqsi and Bulo Burti districts, Ceel Buur and Cabudwaaq in Galgaduud, and most parts of western Muduug. The rest of the country is likely to experience scattered light showers throughout the week as per the forecast.

The Food and Agriculture Organization’s Somalia Water and Land Information Management (FAO SWALIM) Project, has finalized the analysis and mapping of the river breakages along the Juba and Shabelle rivers using very high resolution satellite imagery. Breakages identified in the map have been classified into four different categories; Open, Overflow, Canal Flooding Point and Closed with sandbags. A legend/Key for further explanation of the different types of breakages is provided. A total of 170 Open points, 46 Canal flooding points, 152 Overflow points and 29 points closed with sandbags have been identified along the Shabelle River while 26 Open points, 10 Canal flooding points, 16 Overflow points and 14 points closed with sandbags have been identified along the Juba River which require immediate attention. Several other points, which are either potential or temporarily closed with sandbags, have also been identified. The forecast ElNino season is likely to result to enhanced rainfall in Somalia and Ethiopian Highlands with high potential of flooding over the Juba and Shabelle rivers especially where open and potential points have been identified. There is therefore an immediate need to close the open points and reinforce areas where there are weak river embankments. Intervening agencies are advised to take advantage of the current dry period until the rains start and carry out temporary or long term measures to close the river breakages. This will see a reduction of riverine flooding in case of heavy rains and consequently a massive reduction in economic losses to the country.

Juba River: High Risk of Riverine Flooding at Dollow, Luuq, and Bardheere and High Risk of Flash Flooding in Gedo region Shabelle River: High Risk of Flash Flooding in Hiraan, Bay and Bakool Regions and Moderate Risk of Riverine Flooding at Belet Weyne, Bulo Burti and Jowhar Juba River Catchment: Following the moderate to heavy rains, significant fluctuations in water levels have been observed along the Juba River since Wednesday 25th November 2023 when SWALIM issued its weekly bulletin. Today’s (29th October 2023) water levels represent an increase from 3.78 m to 5.46 m at Dollow, an increase from 4.58 m to 6.20 m at Luuq, an increase from 7.10 m to 9.00 m at Bardheere, and a slight decrease 7.40 m to 7.00 m at Bualle. The rains over Bardheere have particularly been heavy with 110.0 mm received on 28th and 86.0 mm received today (29th November 2023) with flash flooding incidences reported. The high flood risk levels have subsequently been surpassed by 46 cm, 20 cm and 80 cm at Dollow, Luuq and Bardheere, respectively. The implication is that the water levels are now just 54 cm, 80 cm and 140 cm below the bankful levels at Dollow, Luuq and Bardheere, respectively. The runoff from the forecast moderate rains over its catchment in the next 24 hours accumulating to about 100 mm in the next three days around the central parts of Gedo region, are likely to sustain the river level rise. The large volume of water upstream is likely to also lead to a rise in the water levels at Bualle to high risk level. There is therefore a high risk of riverine flooding along the entire stretch of Juba River particularly at Dollow, Luuq and Bardheere. There is also a high risk of flash flooding in Gedo region particularly areas bordering Kenya. Shabelle River Catchment:Fluctuations in water levels have also been observed along the Shabelle River. Today’s (29th October 2023) water levels represent an increase from 6.22 m to 6.40 m at Beletweyne, an increase from 5.48 m to 5.76 m at Bulo Burte, and a slight decrease from 4.28 m to 4.20 m at Jowhar. These fluctuations mean that water levels are now just 10 cm, 74 cm and 80 cm below moderate flood risk levels at Beletweyne, Bulo Burte and Jowhar, respectively. Although moderate rains received in Hirshabelle have not been at stations near the main river channel, the runoff from the forecast heavy rains over its catchment in the 24 hours accumulating to over 10 mm in the next three days in some areas in Hiraan, are likely to lead to a sharp rise in the river levels. Similarly heavy rains are likely in some areas in Bakool and Bay region. There is therefore a high risk of flash flooding in low lying and other vulnerable areas in densely populated areas in Hiraan, Bakool and Bay region. There is moderate risk of riverine flooding along the entire stretch of Shabelle River worsening to high risk after three days.

Moderate to heavy rains expected over central and southwestern areas of the country during the coming week. The rains over Gedo and Bakool are likely to be observed in the first part of the forecasting period. The spatiotemporal distribution of the forecast rains is as below. Heavy rainfall of above 100 mm is expected over Bakool, central parts of Gedo, southern parts of Hiraan and isolated areas in northern Galgaduud, localized areas in Galkayo in Mudug and southern parts of Sool. The rainfall over Ceel waaq in Gedo, Tayeeglow in Bakool, western parts of Bulo Burti in Hiraan and western parts of Ceel dheer in Galgaduud is likely to exceed 150 mm. Moderate rainfall of between 50 and 100 mm is expected in Ceel Waaq and Garbahaarey districts in Gedo region, Baydhaba ditricts in Bay, Xudun, Ceel Barde, Tayeeglow districts in Bakool region, western parts of Bulo Burti district, northern parts of BeletWeyne district and western parts Jalalaqsi district in Hiraan. In the central parts of the country, rains of similar amounts are expected over Dhuusamareeb district and southern parts of Cadaado districts in Galgaduud region, Galkayo district, western part of Jariiban district and several isolated areas in Mudug region. Towards the north, comparatively moderate rainfall is also expected over Burtinle district in Nuugal region, southern parts of Qardho district in Bari region, central parts of Taleex districts in Sool region, southern parts of Las Anod, Buuhoodle district in Togheer, Ceel Afweyn town and it’s border areas with Erigavo in Sanaag region. Light rainfall of below 50 mm is anticipated over the rest of the country with the exception of noncoastal areas of Awdal region, Hargeisa and Gebiley districts in Woqooyi Galbeed region, western parts of Bari region particularly over Bosasso district.

Somalia grapples with the looming impacts of an impending El Niño, exacerbating the ongoing climate change challenges. Recurrent riverine and flash floods, particularly in urban centers are of significant concern. Urgent action is needed to prepare for and mitigate the forthcoming El Niño floods, aiming to safeguard lives and mitigate economic losses. Key to this strategy is proactive flood management, involving timely evacuations to higher ground. Identifying suitable elevated areas serves a dual purpose, ensuring safety and facilitating aid delivery. In this regard a rigorous GIS & RS methodology by SWALIM considered nine crucial factors, such as historical flood extent, elevation, slope, topographic wetness index, drainage density, strategic boreholes, settlements, land cover, and roads, to isolate higher grounds suitable for evacuation. The resulting maps show safe areas for evacuation in case of flooding, while exercising discretion considering factors like proximity to schools, healthcare facilities, pest prevalence and any other unforeseen factors

Moderate Risk of Flooding Along Juba River Particularly at Luuq and Bardheere Heavy rains received over Luuq (80.5 mm), and moderate rains (26.2 mm) observed over Dollow on 20th October 2023, coupled with moderate rains across the Ethiopian border have resulted to a sharp rise in river level at Luuq from 3.84 m on 18th to 5.6 m and at Dollow from 4.26 m on 19th to 4.78 m today. Added to previous light rains (14.1 mm) observed on 19th October at Luuq, moderate flood risk levels have been surpassed by 0.22 m and 0.1 m at Dollow and and Luuq, respectively. These localized rains also led to flashfloods affecting IDP camp at Luuq. Moderate rains received over Beletweyne (38.5 mm) on 20th October 2023, and possibly more intense rains over the surrounding areas, coupled with moderate rains across the Ethiopian border have led to a noticeable rise in river level at Beletweyne from 4.95 m on 19th to 5.15 m today (20th October 2023). The rainfall forecast for the next three days indicates moderate to heavy rain (50 – 150 mm) within the Somali-Ethiopia border particularly over upper parts of Gedo region, central parts of Bakool region and many parts of Hiraan region. Although only light rains (4 mm) have been observed at Bardheere today (20th October), the forecast moderate rains in the 24 hours and coming days over upper parts of Gedo region, is likely to lead to further rise in the river levels with moderate risk of flooding along the entire Juba River stretch with the flood wave expected at Bardhere within 2 days. This is therefore an alert to trigger both riverine and flash floods anticipatory actions and to caution communities living along the Juba riverine areas particularly Luuq and Bardheere districts to be vigilant and heed to anticipatory measures as the river levels keep rising. Although the risk of flooding along Shabelle River remains low today, the forecast moderate to heavy rains over Hiraan will lead to increase in river levels. If the heavy rains over Hiraan materialize, it may result in incidences of flash floods today and whose resultant run off and flood wave is expected to flow downstream towards Bulo Burte Burte and Jalalaqsi in the coming days. Additionally, the large volumes of water that was sighted at Limey district in Ethiopia which forms part of the upper catchment of Shabelle river, is likely to lead to a rise in water level at Beletweyne in two to three weeks.

Given the recent evolution of warmer than average Sea- Surface Temperatures (SSTs) over the central and eastern equatorial Pacific Ocean, most global climate models have confirmed the presence and persistence of El Niño conditions throughout the October - December 2023 season. Moreover, similar warming of ocean waters near the East African coastline, together with cooling down of the waters near the western Australian coastline, which technically defines a positive Indian Ocean Dipole (IOD), is expected to lead to above normal rains over most parts of East Africa. Somalia’s Deyr (October - December) “short rains” season is associated with the somewhat-faster southward movement of the Inter-Tropical Convergence Zone (ITCZ) which dictates much of the country’s climate. According to ICPAC, the climate outlook for the “Deyr Short Rains’’ season indicates an exceptionally high likelihood (85 %) of enhanced rainfall over southern parts of the country encompassing the catchments of both Juba and Shabelle Rivers where up to 10 consecutive rainy days are probable. Upstream of the river catchments across the Ethiopian border, 4 - 6 consecutive rainy days are expected with higher likelihood of cumulative amounts exceeding 150 mm. In terms of associated risks, the enhanced amounts, more so consecutive rainy days, over Juba and Shabelle River catchments within the country and across the Ethiopian border will likely lead to flooding as from the third week of October. However, the forecast dry conditions over the southern parts of Somalia where the two river catchments lie in the month of September offer some lead time for intervention measures to be put in place to mitigate the potential flood risks. The forecast dry conditions over the agricultural zones in the southern parts of the country in the month of September are also opportune for land preparation. The subsequent rains will likely lead to substantial recharge of water sources, replenished water catchment levels, and improved soil moisture conditions. These will create favorable conditions for grass regeneration, offering fodder for the livestock, and timely crop planting across the agro-pastoral livelihoods.
