Somalia: Flash Floods - Apr 2018Ongoing
Unlike in 2017 when the rains were poor, the above average Gu rains in April this year are already worsening conditions in overcrowded Internally Displaced Persons (IDP) settlements and displacing more people along riverine areas due to flooding...In Baidoa, half of the estimated more than 246,000 IDPs, are at the risk of flash flooding...In Galgadud region, heavy rains resulted in flash floods that destroyed IDPs shelters in settlements in low lying land in Abudwaq town...An estimated 9,300 displaced people in Danwadaag, Kulmiye and Wadajir settlements have been affected and an unknown number has moved to Cadaado town until flooding recedes...In Jubaland, an estimated 28,200 people have been displaced by flash flooding. This includes 8,000 in Saakow; 6,000 in Bu’ale; 6,000 in Luuq; 6,000 in Afmadow; 1,200 in Ceel Waaq villages and some 7,000 people in Jilib and Jamaame riverine areas who have been temporarily displaced to nearby highland areas. In Middle Shabelle, the Shabelle River burst its banks displacing people in Horseed area. Farms and IDP shelter were washed away.

Overall, more than 427,000 people have been affected as of 26 April and of these nearly 175,000 have been displaced as a result of the flash and river flooding in Hirshabelle, South West and Jubaland states as well as Banadir region, according to data collected by humanitarian partners. (OCHA, 26 Apr 2018)
Flash and river flooding has so far affected an estimated 630,000 people. More than 214,800 of these have been displaced from their homes following the heavy rains received across the country in April, according to the UNHCR-led Protection & Return Monitoring Network (PRMN). (OCHA, 2 May 2018)
An estimated 772,500 people have been affected by the flooding and more than 229,000 are displaced, according to [PRMN]. According to the FEWS NET and FSNAU, the food security outcomes are likely to be more severe than previously projected for many families in areas affected by flooding, especially in riverine areas of Hirshabelle, Jubaland and some agropastoral areas of South West State. In these areas, several roads are now impassible and trade flows are expected to slow, driving food prices higher.Cases of AWD/Cholera are expected to rise as flood waters stagnate and remaining clean drinking water sources are compromised. (OCHA, 15 May 2018)
The past week has seen a reduction in rainfall activity across Somalia and in the Ethiopian highlands, according to FAO-managed Somalia Water and Land Information Management (SWALIM). However, river levels remain high with flooding continuing along the Shabelle, while water levels are reducing down the Juba River, according to SWALIM. In Belet Weyne town and surrounding areas in Hirshabelle state, flood waters are receding while in Bulo Burto and Jalalasqi flooding levels have increased... The floods and storm have resulted in deaths and affected livelihoods, livestock, shelter and key infrastructure across the country. There is a high risk of the outbreak of water-born communicable diseases including malaria and AWD/cholera in several areas. An estimated 794,761 people have been affected by the flooding in southern and central states and more than 231,335 are temporarily displaced, according to the UNHCR-led Protection & Return Monitoring Network (PRMN). So far, 21 people are confirmed dead including nine in Hirshabelle State, four in Jubaland State and eight in Banadir region. (OCHA, 25 May 2018)

This map illustrates satellite-detected flood water extent and IDP distribtuion within the town of Belet Weyne in Belet Weyne District,Hiiran Region, Somalia. The analysis was conducted analyzing GeoEye-1 & WorldView-3 images acquired on the 30 April & 1 May 2018. As observed from the satellite image, the town of Belet Weyne is completely affected by the floods. Around 70% of the extension of the town is totally inundated, being the districts of Bulahabley, Bundaweyn, Dhagahjebis, Hilac, Hindab and Lamagalay Regional Military Based, Radar and Kutimbo completely submerged in water.
A recent spike in seasonal rainfall in parts of East Africa, which has previously been suffering from long periods of drought, has resulted in widespread flooding across large parts of Somalia, Kenya and now Ethiopia.
This map illustrates satellite-detected flood water extent over the district of Belet Weyne, Hiraan region, Somalia using a SAR image from 06 May 2018 and an optical VHR image over Beledweyne town.
More than 2800 km2 of lands were assessed and about 19,000 ha (190km2) appear to be inundated which corresponds to about to about 7% of the total analysed zone. In this analysed area and according to WorldPop data the population is estimated to ~126,000 people, ~ 32,000 live in the flooded zone and about 70,000 within 100 meters distance from the flooded areas.
This map illustrates satellite-detected flood water extent within the town of Belet Weyne in Belet Weyne District,Hiiran Region, Somalia. The analysis was conducted analyzing GeoEye-1 image acquired on the 30 April 2018. As observed from the satellite image, the town of Belet Weyne is completely affected by the floods. More than 50% of the extension of the town is totally inundated, being the districts of Bulahabley, Bundaweyn, Dhagahjebis, Hilac, Hindab and Lamagalay Regional Military Based completely submerged in water.
Enhanced rains are foreseen in the coming week in many parts of the country with Bay and Bakool regions in the south expected to record the highest amounts of rainfall. The Ethiopian highlands will also continue to receive good rains during the period in forecast.
The foreseen moderate to heavy rains are likely to exacerbate ground conditions, and trigger additional floods. Built up and low Lying areas of Bay and Bakool will experience flash floods while river flooding along the Juba and Shabelle Rivers will continue.

This map illustrates satellite-detected flood water extent over the districts of Saakow and Bu'aale, Middle Juba, Somalia. The mostly affected areas are in the district of Saakow, where 365 km2 of land are flooded. In total, 19 settlements are within the inundated zones: 12 in Buaale and 7 in Saakow; however, more than 100 settlements, are within 500 meters distance from the flooded areas and might be affected due to the proximity to Juba River.
