HIGHLIGHTS Heavy rains beginning on 14 March triggered widespread flooding across northern Syria, impacting rural communities and displacement sites across. Aleppo, Idleb, Ar-Raqqa, Al-Hasakeh, and Deir-ez-Zor governorates. Four children were killed in Ar-Raqqa, due to the collapse of a mudbrick home, while more than eighty tents in informal settlements were destroyed or flooded, forcing families to relocate. On 25 March, the Ministry of Emergency and Disaster Management (MoEDM) issued a report detailing the impact of the rains so far and has deployed a senior technical staff to Al Hasakeh to work with authorities and responders. Across Aleppo and Idleb, flooding affected more than 19, 000 people (3, 453 families) and damaged 3, 429 shelters, including hundreds that were completely destroyed. In Aleppo, rising water levels in the As Seyha dam have already affected agricultural land and could put at risk 8 villages downstream if the dam structure gives way. In Al-Hasakeh, more than 1, 436 families were displaced from flooded homes and camps, with at least 6, 020 people are confirmed as displaced in Tel Hmis, Areesheh, Al-Malikeyyeh sub-districts, as well as Al-Hasakeh and Quamishli cities. Immediate priorities include emergency shelter support, NFI distributions, clearing of flooded access routes, restoration of safe water, and urgent action to address escalating protection risks linked to mine migration, displacement and unsafe shelter conditions. Humanitarian organizations are scaling up response efforts across all affected areas, but the scale of flooding and displacement requires additional resources and strengthened coordination to avoid duplication and ensure comprehensive coverage. SITUATION OVERVIEW AND HUMANITARIAN IMPACT Heavy rains that began on 14 March triggered widespread flooding across northern Syria, initially affecting Idleb and Aleppo governorates before extending eastwards into Ar-Raqqa, Al-Hasakeh and Deir-ez-Zor. Across the affected areas of Idleb and Aleppo, flooding impacted around 19, 056 people (3, 453 families) and damaged 3, 429 shelters, including hundreds that were totally destroyed. In Al-Hasakeh, more than 1, 436 families were displaced from damaged homes and flooded camps, with at least 6, 020 people confirmed as displaced. The intensity and geographic spread of the storms caused extensive shelter destruction, the collapse of vulnerable mud-built housing, contamination of water sources, significant agricultural losses and heightened protection risks in multiple districts. A new weather depression arriving on 24 March further deteriorated conditions in eastern Syria and is likely to significantly affect most communities along the Al-Khabur river basin, which is now seeing fast-flowing water for the first time after several years of drought conditions.
