The International Rescue Committee (IRC) is mounting an urgent response to severe flooding that has swept across southern Yemen. More than 100,000 people have been affected by flash floods, triggered by torrential rains, that have destroyed homes – including camps for already displaced families – and left farmland submerged. Critical infrastructure such as roads, power lines, and water and sanitation facilities have also been severely damaged, cutting off communities from essential services and forcing thousands into secondary displacement. The IRC warns that with more heavy rain expected, the risk of further flooding threatens to displace even more families and cause additional suffering to vulnerable communities already at the epicenter of a devastating hunger crisis. (IRC, 26 Aug 2025)
According to the Yemen Red Crescent Society (YRCS) and partner reports, 47,050 households (329,350 individuals) have been affected by the floods. The crisis has resulted in 62 fatalities, 73 injuries, and 4 missing persons. Importantly, 27,332 internally displaced households (191,324 individuals) are included in these figures, showing that IDPs are among the most heavily impacted groups. The flooding has caused extensive damage to homes, critical infrastructure, including bridges, roads, and hospitals, IDP shelters, farmland, and public services. Several districts remain inaccessible due to blocked roads, while displacement is rising in low-lying areas and camp settings. (IFRC, 3 Sep 2025)
[…] as of 17 September, reports 82 fatalities, 100 injured people, and approximately 386,000 people affected across 125 districts in 19 governorates. Flooding has damaged several infrastructure and croplands, and roads have been submerged isolating people from essential services. (ECHO, 18 Sep 2025)
Roads have been damaged or submerged underwater in multiple governorates, cutting off people’s access to essential services and humanitarian assistance. Floods have caused widespread damage to agricultural lands and infrastructure, including terraced farms, irrigation systems and livestock
assets. Soil erosion and the collapse of water diversion structures have disrupted water access, while the destruction of crops and farming tools have severely impacted food production. […] Protection risks have increased in cases where landmines and ERW have shifted into residential areas due to the floodwaters. The risk of disease outbreaks is increasing, especially due to damaged WASH facilities and infrastructure, including collapsed sanitation systems, sewage overflow and the presence of stagnant water. 56 health facilities have reportedly been directly or indirectly impacted since 1 August, and schools in multiple governorates have been damaged and forced to close.

[…] as of 24 September, reports 62 fatalities, 95 injured people, and approximately 431,033 people affected across 141 districts in 20 governorates. (ECHO, 25 Sep 2025)
As of 29 September UN OCHA reports 82 fatalities, 100 injured, nearly 455,500 affected people across 156 districts throughout 20 governorates. Marib governorate is among the worst impacted with Marib Al Wadi district, counting 61,824 affected people, and Marib City district – 43,274 affected people. In Al Hodeidah governorate, 50 610 affected people are reported in Al Khukhah district – already facing a dire humanitarian situation with some of the highest rates of malnutrition in Yemen.
