Torrential rains triggered deadly floods and landslides across Southeast Asia, pushing the death toll to more than 900, while hundreds remain missing.

A rare tropical storm formed in the Malacca Strait and hit Indonesia, Thailand, and Malaysia, while another storm drenched Sri Lanka and pushed rain toward India’s southern coast.

Indonesia suffered the worst damage. Cyclone Senyar triggered massive landslides on Sumatra, killing 435 people and leaving 406 missing. Rescue teams are struggling to reach remote villages as helicopters drop food and water. More than 213,000 people remain displaced.

In Thailand, flooding killed 170 people, with Songkhla Province hit hardest. Hat Yai city recorded its heaviest rainfall in 300 years, affecting nearly 3 million people.

Sri Lanka reported 334 deaths after Cyclone Ditwah triggered mudslides that impacted more than 1.1 million people—thousands who lost their homes and are now staying in temporary shelters set up in schools.

Malaysia reported three deaths and continues to shelter around 18,700 evacuees. The government lifted storm warnings but urged citizens in Indonesia’s West Sumatra to register for assistance.

Experts warn that climate change is making extreme weather more frequent across Southeast Asia.
