COLOMBO, Sri Lanka — At least 635 people have been killed, and tens of thousands remain in crowded shelters after Sri Lanka cyclone Ditwah tore through the island in late November, inundating homes and triggering deadly landslides across all 25 districts, Sri Lankan officials and aid agencies say. The storm swamped entire villages, cut roads and power, and left survivors too afraid to return to cracked hillsides and half-buried houses as the government races to extend relief and seek fresh support from the International Monetary Fund, officials said, Dec. 11, 2025.
Survivors of the Sri Lankan cyclone Ditwah fear returning home.
In the central highlands village of Kithulbadde, residents shuttle between damaged homes and makeshift dormitories in schools and temples, saying deep fissures in the earth and cracked walls make it too risky to sleep in their own houses. Many of those displaced are tea pickers and small farmers who lost both homes and crops when Sri Lanka’s cyclone Ditwah sent torrents of mud crashing down steep slopes.
Nationwide, nearly 70,000 people are still living in temporary shelters, including classrooms now packed with families sleeping on mats and pushed-together desks, according to child-rights groups. One assessment by Save the Children estimates that more than 630 people were killed, at least 86,000 homes were damaged, and tens of thousands of children are entering a second week in crowded centers needing mental health support after the floods and landslides. Save the Children says the noise, heat, and uncertainty are compounding children’s trauma as they try to study for exams in camp conditions.
The World Health Organization has described a nationwide emergency, with more than 1.4 million people affected, over 230,000 displaced into roughly 1,400 active shelters, and hundreds still missing. Its early situation report warns that clean water, food security, and basic health services are under severe strain as Sri Lanka cyclone Ditwah’s floodwaters contaminate wells and damage clinics. WHO’s regional office says the human toll is heaviest in central and south-central districts, where landslides have repeatedly cut access for rescuers.
Scale of damage from Sri Lanka cyclone Ditwah strains fragile recovery
A new analysis for the United Nations Development Programme suggests Ditwah caused one of the largest flood events in Sri Lanka’s recent history, submerging about 1.1 million hectares — roughly one-fifth of the country’s land mass — and directly exposing some 2.3 million people to cyclone-driven flooding. The study, which combines satellite flood maps with vulnerability data, finds nearly 720,000 buildings exposed to floodwaters, including hundreds of schools and 243 health facilities. The UNDP-backed assessment warns that more than half of those living in inundated areas were already facing unstable incomes and high debts before the storm.
Researchers with the World Weather Attribution group say the heavy rains that powered Sri Lanka cyclone Ditwah and a companion storm in Indonesia were “supercharged” by warmer seas, with sea surface temperatures in the North Indian Ocean about 0.2 degrees Celsius above the recent average and likely around 1 degree cooler without human-driven warming. Their study, cited in a Reuters analysis, estimates Ditwah’s floods and landslides pushed Sri Lanka’s disaster losses to around $7 billion, with the death toll surpassing 600.
Those losses hit just as Sri Lanka was beginning to emerge from its worst economic crisis in decades. The country is already under a multiyear, $3 billion IMF bailout agreed in 2023 after mass protests, fuel queues, and sovereign default, detailed in a Reuters timeline of the 2022–23 crisis. That account traces how Sri Lanka’s public finances collapsed, forcing deep spending cuts and tax hikes that have left many households with little buffer against a shock like Ditwah.
Past disasters and IMF ties shape Sri Lanka’s response.
The catastrophe of the Sri Lankan cyclone Ditwah is part of a grim pattern. In 2017, monsoon floods and landslides linked to Cyclone Mora killed at least 208 people, displaced about 600,000, and destroyed thousands of homes, according to official tallies compiled in accounts of the 2017 Sri Lanka floods.
Just a year earlier, a relatively weak system, Tropical Storm Roanu, still triggered deadly landslides and flooding across 22 of Sri Lanka’s 25 districts, killing around 75 people and leaving thousands of homes inundated. A United Nations disaster-monitoring brief on Sri Lanka’s landslides and torrential rains due to Roanu warned even then that the island’s terrain and settlement patterns made it especially vulnerable to intense downpours.
Analysts say what sets Ditwah apart is that it struck a country already living under IMF fiscal targets and debt restructuring. The current Extended Fund Facility, approved in 2023 and reviewed again earlier this year, ties loan disbursements to tighter budgets, higher revenue collection, and social safety net reforms, leaving policymakers with limited room to ramp up spending even after a disaster.
IMF weighs urgent financing for Sri Lanka cyclone Ditwah recovery
In Washington, the IMF has confirmed that Sri Lanka has requested about $200 million in additional emergency financing under its Rapid Financing Instrument to address the damage from Cyclone Ditwah. In a statement issued by Mission Chief Evan Papageorgiou, the Fund said the request — worth roughly 26 percent of Sri Lanka’s IMF quota — is under consideration by its executive board and stressed that it “remains closely engaged” with Colombo as it recovers and rebuilds. The IMF statement on Sri Lanka frames the new aid as additional to the existing bailout program.
The government hopes rapid IMF approval will help unlock further concessional loans and grants from other lenders and give it space to finance cash aid, house rebuilding, and crop-replanting schemes for families hit hardest by Sri Lanka’s cyclone Ditwah. Economists, however, warn that even with fresh funds, the disaster is likely to slow growth and deepen poverty in districts that were only starting to recover from years of economic turmoil.
For now, life in the relief centers is measured in queuing for water, sharing school floors at night, and watching weather forecasts with dread. With climate scientists warning that warmer seas are making storms like Sri Lanka cyclone Ditwah sharper and wetter, the choices Sri Lanka and its creditors make in the coming weeks — about debt relief, reconstruction, and relocation from the riskiest slopes — will help decide whether this disaster becomes a turning point or another step in a worsening cycle of climate and debt shocks.
