Somalia Rainfall Forecast – Issued 28 March 2024

This forecast period marks the transition from the tail-end of Jilal to the forecast Gu season onset. Based on NOAA-NCEP Global Forecasting System (GFS), moderate to heavy rains are expected over most parts of Somaliland, Jubaland, South West, Hirshabelle, and Galgaduud with dry conditions likely to continue over most parts of Puntland. The cloudiness and rains in the northern parts of the country are likely to be mediated by the north easterly winds ascending the east-west oriented elevations. While patches of clouds and isolated rains are likely over the elevated areas in Sanaag and Bari, the intensity of the rains over Awdal and Woqooyi Galbeed on the windward sides of the Harage Highlands across the Ethiopian border. The forecast rains in the southwestern parts of the country are likely to be driven by the arrival of the Inter Tropical Convergence Zone (ITCZ) and therefore signal the onset of Gu rains. The temporal and spatial distribution of the forecast rainfall (Map 1) are as follows: Heavy cumulative rainfall between 100 mm and 150 mm is forecast over western parts of Badhaadhe district and central parts of Kismaayo district in Lower Juba region, central areas of Bardheere district and northern areas of Luuq district in Gedo region, central areas of Belet Weyne district in Hiraan region, eastern parts of Dhuusamareeb district in Galgaduud region and eastern parts of Burco district in Togdheer region. The rains over isolated places in these areas particularly Badhaadhe in Lower Juba, Bardheere and Luuq districts in Gedo region and Dhuusamareeb district in Galgaduud region are likely to be more intense leading up to more than 150 mm. As the week progresses the very heavy rains over Bardheere district in Gedo region are likely to sum up to more than 200 mm. It is noteworthy that such rains are likely to fall within the in-country catchments of both Juba and Shabelle Rivers. Moderate cumulative rainfall of between 50 m and 100 mm is expected over most places in the following areas: Badhaadhe, Kismaayo and Jamaame districts in Lower Juba region, Bardheere and Luuq districts in Gedo region, Belet Weyne district in Hiraan region, Dhuusamareeb district in Galgaduud region, Burco district in Togdheer region, Gebiley district and western parts of Hargeisa district in Woqooyi Galbeed region, Baki and Borama districts in Awdal region. Moderate rains are also likely over Jilib district in Middle Juba region, Garbahaarey district in Gedo region, Qansax Dheere district in Bay region, Tayeeglow district in Bakool region, Bulo Burte district in Hiraan region, Sheikh district in Togdheer, Berbera district in Woqooyi Galbeed region, and Ceerigaabo district in Sanaag region. The rains in the northern parts of the country particularly those over the northern border between Gebiley and Hargeisa districts are likely to be observed earlier between 27th and 29th March 2024. Light cumulative rainfall of less than 50 mm is forecast over most of the other places in Awdal, Woqooyi Galbeed, Togdheer, Lower Juba, Gedo, Bay, Bakool, Middle Juba, Lower Shabelle, Middle Shabelle, Hiraan, and Galgaduud regions. Light rainfall is also likely over most parts of central and northern parts of Ceerigaabo district in Sanaag region and a few places in Bosasso and Qandala districts in Bari region. It is important to point out that the rains over the upper catchments of both Juba and Shabelle Rivers will be light to moderate in intensity. Dry conditions are likely to prevail over vast areas in Mudug region, Nugaal region, Sool region and Bari region. Dry conditions are also expected over a few places in the following areas: Ceel Afweyn and Laasqoray distrcist in Sanaag region, Cabudwaaq and Ceel Dheer districts in Galgaduud, Balcad district in Middle Shabelle, Qoryooley, Sablaale and Baraawe districts in Lower Shabelle, eastern parts of Bu’aale district in Middle Jubas, northern parts of Afmadow district in Lower Juba region.

Review of Deyr 2023 Rainfall Performance, Jilal Status, Gu Outlook, and Implications on Livelihoods over Somalia

Several key findings have been obtained following a review of the 2023 Deyr (October-November-December) seasonal rainfall. Heavy cumulative rainfall was observed over the south and central parts of the country with a substantial 1,152 mm being recorded in Baidoa in Bay region representing five times of the station’s Long-Term Mean (LTM). The rainfall was even much heavier in Berbera in Wooqoyi Galbeed Region where the amount was 26 times the LTM. The Deyr rains began in early October over parts of Somaliland and central parts of Puntland spreading southwards to Gedo and Bay-Bakool regions. However, there was a sharp end to the Deyr rains particularly over Puntland and Somaliland with no single rainy day observed in Puntland in December. There was more than 30 consecutive dry days in almost all the stations in the country between 1st October and 31st December 2023. The observed rainfall amounts, and the length of wet spells particularly over the Juba and Shabelle River basins within the country were 100% in agreement with the forecast. The onset of Deyr rains across the country was also generally in agreement with the forecast with most of the stations realizing onset within a week of the forecast date.

Somalia Rainfall Forecast – Issued 13 December 2023

Light rainfall of below 50 mm is forecast over some areas in the southern parts of the country in the coming week. These light rains are expected in the earlier part of the forecast week (13th – 15th December) over Badhaadhe, Kismayo and Jamaame districts in Lower Juba region, Ceel Waaq and Belet Xaawo districts in the Gedo region. Other areas expected to receive the light rains are the coastal areas of Jilib district in Middle Juba region, Marca and Kurtunwaarey districts, areas in the Sablaale, Qoryooley, and Barawe districts in Lower Shabelle region, and Baidoa in Bay region. Although moderate in cumulative amounts, the rains over the Lower Juba region are likely to be spread out across the entire week and will therefore be less intense. Moderate rains above 50 mm may be observed in some areas along the southern coastal strip whenever the monsoonal winds blowing parallel to the coastline are accentuated by any elevated East-West oriented terrain. As these monsoonal winds blow southwards across the Gulf, there are also chances of trace amounts of rains over the northern coastal strip including Caluula and Qandala districts in Bari region and Berbera districts in Woqooyi Galbeed region. Dry conditions – The rest of the country is expected to remain dry during the coming week. The model predictions of minimal rainfall amount across the country and the Ethiopian highlands in the month of December signals the end of the Deyr rainy season for Somalia.

Somalia Flood Advisory for Juba and Shabelle Rivers - Issued 13 November 2023

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.
