Since mid-November, seasonal monsoon rains and Tropical Storm (TS) Senyar have triggered widespread floods and landslides across parts of southern Thailand, Peninsular Malaysia and Indonesia’s Sumatra region. The impact has been particularly devastating on Indonesia: at least 753 people have been killed and 2,600 others injured. 570,000 people have been displaced across Aceh, North Sumatra and West Sumatra provinces.
In southern Thailand, which has been impacted by seasonal heavy rainfall, at least 145 people have been killed. A state of emergency was declared in Songkhla, which alone recorded 104 fatalities. One of the worst-hit areas within the province was Hat Yai, where many tourists were stranded in partially submerged buildings.
In neighbouring Peninsular Malaysia, at least one person was killed in Kelantan state. Two others died in Perlis state due to the impact of the monsoons and TS Senyar in late November.
At least 13,662 people remained at relief centres across the states of Perak, Selangor, Perlis, Terengganu, Kelantan, Pahang, Kedah and Negeri Sembilan.
What to Expect:
Further seasonal heavy rainfall is possible over southern Thailand until the end of December and is likely over Peninsular Malaysia and Indonesia’s Sumatra region through January 2026.
