Somalia Flood Advisory For Juba And Shabelle Rivers - Issued 02 November 2023

Juba River Catchment Over the past three days, there has been a notable increase in both the amount and intensity of rainfall in the Gedo region and the Ethiopian highlands. The current water levels along the Juba River are now only 8 cm below bankful level at Dollow, 14 cm at Luuq, and under 40 cm at Bardheere. The ongoing heavy rainfall, coupled with the forecasted moderate rains in the next 24 hours, with an accumulation of approximately 150 mm over the next three days across Gedo, are expected to cause the river level to reach bankful height. This presents a high risk of riverine flooding along the entire stretch of the Juba River. Additionally, there is a high risk of flash flooding in the Gedo region, particularly in the Garbahaarey district within the next 24 hours. Residents in Deeday, Buulo Oomin, Tuutees, and Dhayba should take all necessary precautions to ensure their safety. Necessary anticipatory action should be taken. Shabelle River Catchment There has been a slight increase in water levels along the Shabelle River. The water levels are currently just 8.0 cm, 50.0 cm and 70.0 cm below the moderate flood risk levels at Beletweyne, Bulo Burte and Jowhar, respectively. The runoff from forecast moderate rains within the catchment over the next three days in HirShabelle, is likely to lead to a gradual rise in water levels with moderate risk of flooding along the Shabelle River. There are also reports of high flood wave approaching the Somali-Ethiopia border which is projected to lead to a significant river level rise in 3 to 4 days. Flash Floods Within the next 24 hours, heavy rains are anticipated over most areas of Bakool and Bay regions. As a result, there is a high risk of flash flooding in low-lying and vulnerable areas, particularly in Buur Hakabar, Diinsoor, Qansax Dheere, and Baydhaba districts in Bay, as well as Waajid and Ceel Barde districts in Bakool. Most parts of Middle Juba, including areas around Jilib, are expected to receive rainfall exceeding 100 mm, with coastal areas of Jilib experiencing particularly high amounts of over 200 mm, posing a significant risk of flash floods especially around Jiirta and Kuunyo-Burrow. Similarly, areas along the border of Hobyo and Jariiban districts in Mudug are likely to receive rainfall exceeding 200 mm, potentially leading to flash floods over Xingaras, Dhinooda, Ceel Dhahanaan, and Ceel Bacduur. Residents around the mentioned areas should take precautionary measures to ensure their safety.

Somalia Flood Update for Juba and Shabelle Rivers - Issued 23 October 2023

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.

Higher Ground For Flood Evacuation In Dollow District and Mapping Methodology

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

Somalia Rainfall Forecast – Issued 25 October 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.

Status of River Breakages Along Juba and Shabelle Rivers - Issued October 2023

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.

Somalia Flood Advisory for Juba and Shabelle Rivers - Issued 29 October 2023

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.
