Heavy rain threatens nearly 950,000 displaced Gazans as winter looms

Nearly 950,000 displaced Palestinians face moderate or high flood risk as the storm approaches. More than 400,000 of them live in areas classified as highly vulnerable. This shows that the threat extends far beyond a few isolated camps. It affects a large share of people already lacking secure shelter.

A further 44,000 people are staying in more than 2,300 buildings considered structurally unsafe. Severe weather could cause parts of those buildings to collapse. The flood-risk and unsafe-building figures describe different dangers, so they should not simply be added without knowing whether some people appear in both groups.

The figures come from OCHA and Gaza's Civil Defense warning. Together, they show why the approaching rain and wind are an emergency. Humanitarian groups are assessing dangerous sites, clearing drainage channels, installing sandbags and helping families raise shelters, but overcrowding and limited safe land make relocation difficult.

The approaching storm could turn fragile shelter into a direct survival threat. Heavy rainfall may inundate tents and temporary shelters, leaving families cold, wet and exposed. Strong winds may rip plastic coverings, loosen tent pegs or destroy structures that have already weakened after months outdoors. Damaged buildings could also partially collapse.

The danger grows because many shelters have been used for more than a year. Their floors, walls and supporting frames have deteriorated. Low-lying sites may flood when damaged drainage networks cannot carry away water. Children, older people and people with disabilities face especially serious risks from prolonged exposure to cold and damp conditions.

Civil Defense urged families to secure coverings, build earthen barriers, dig drainage channels and raise belongings above ground. It also advised people to avoid damaged buildings and nearby areas. Yet safer accommodation is scarce, so many families may remain exposed despite taking precautions.

Flash flooding is a rapid rise and flow of rainwater after heavy rainfall. It can spread quickly across low-lying ground, inundating shelters before families have time to move. For displaced people living in tents, even shallow flooding can soak bedding, damage belongings and make a site unsafe.

Gaza's low-lying displacement sites are especially vulnerable because drainage networks have been damaged. Rainwater cannot move away efficiently, and some tents sit in dry riverbeds, rainwater collection ponds or exposed coastal areas. The Winter Emergency Committee identified about 7,800 tents in particularly hazardous locations.

The response is further limited by shortages of pumps and destroyed municipal equipment. Humanitarian groups are clearing drainage channels, installing sandbags and helping families elevate shelters. Still, only a handful of aging vacuum tanker trucks and limited portable pumps are available. Heavy rain could therefore overwhelm sites faster than responders can drain them or evacuate families.

The conflict destroyed residential neighborhoods and forced much of Gaza's population from their homes. Israel's military offensive began in October 2023, and the displacement crisis has continued for more than three years, according to the article. With homes damaged or destroyed, families have depended on tents, makeshift shelters and designated centers.

The scale is stark. Gaza's government media office reported more than 2.15 million displaced Palestinians across the enclave in August 2026. Approximately 867,000 were living in deteriorating tents, while more than one million were sheltering in designated centers. OCHA also said 294,250 families need shelter assistance before the rainy season.

Long exposure has made temporary shelter less reliable. Many tents have been used for over a year, and more than 60% reportedly need immediate replacement. Around 200,000 worn-out tents shelter hundreds of thousands of people. Continued conflict, overcrowding and restricted access make replacing them or providing durable homes extremely difficult.

Flood response depends on working drainage systems, vehicles, pumps and rescue tools. In Gaza, those systems and resources have been severely damaged. When rain falls heavily, water can remain trapped in low-lying sites, while responders have fewer ways to clear it, evacuate families or reach people inside damaged structures.

The article reports that about 70% of municipalities' primary operational equipment and 90% of Civil Defense rescue equipment have been destroyed. Responders have only a handful of aging vacuum tanker trucks and a limited number of portable water pumps. Damaged drainage networks also reduce the routes available for moving accumulated water away from shelters.

This creates a dangerous delay. Flooding may spread while teams struggle to drain sites or assist residents. Humanitarian organizations are clearing channels, placing sandbags and helping families raise shelters, but those measures cannot replace missing equipment. If heavy rain overwhelms several vulnerable areas at once, response capacity may be stretched immediately.

Moving away from a threatened shelter requires somewhere safe, accessible and available. Gaza's displaced families often lack all three. The article describes severe overcrowding, restricted access to parts of the enclave and a shortage of suitable land. These conditions make relocation difficult even when a tent sits in a flood-prone or otherwise dangerous location.

Some tents are placed in dry riverbeds, rainwater collection ponds and exposed coastal areas. Humanitarian agencies have helped some families relocate voluntarily from particularly hazardous sites. But alternative accommodation remains limited, and many families are already living in designated centers or deteriorating tents. Moving them can simply shift pressure to another crowded location.

Civil Defense called on humanitarian organizations and community groups to provide alternative shelter urgently. The need is large: OCHA reported that 294,250 families require shelter assistance before the rainy season. Without more suitable places, families may have to reinforce unsafe shelters or remain exposed when severe weather arrives.

Adequate shelter means more than having a tent overhead. It must protect people from rain, wind, flooding and cold, remain structurally safe, and provide enough space for families and their belongings. It also needs usable surroundings, including drainage and access for emergency help. These protections matter because prolonged exposure can seriously harm children, older people and people with disabilities.

The article shows how far current conditions fall short. Many tents have been used for more than a year, with deteriorating floors, walls and frames. Families are advised to secure coverings, dig drainage channels and raise belongings. Others are sheltering in damaged buildings that could partially collapse. About 58% of people needing shelter assistance face critical or catastrophic needs.

Durable housing is hard to provide during prolonged conflict because residential neighborhoods were widely destroyed. Overcrowding, restricted access and a severe shortage of suitable land limit alternatives. The scale is enormous: around 1.98 million people need shelter and nonfood assistance, while 294,250 families need help before the rainy season.
