Urgent Flood Warning Issued for Koh Samui
Authorities have issued an urgent alert for Koh Samui due to heavy rainfall and high tides, warning residents and visitors of potential flash floods and landslides.
On November 12, 2026, Thailand's Department of Disaster Prevention and Mitigation (DDPM) issued an urgent warning for Koh Samui, Surat Thani province, following persistent heavy rainfall. The combination of continuous rain and high sea tides has created a significant risk of flash floods, forest runoff, and landslides in the area. Residents and tourists in low-lying regions or near mountain slopes are advised to move belongings to higher ground and exercise extreme caution regarding electrical hazards. The DDPM, in coordination with major mobile network operators, has utilized the Cell Broadcast system to disseminate emergency alerts directly to mobile devices in the affected area. Authorities emphasize the importance of monitoring official government updates closely. For those requiring assistance, reports can be made to local administrative leaders or via the 1784 emergency hotline. Additionally, the DDPM has established a dedicated Line account, 'ปภ.รับแจ้งเหตุ 1784', for reporting incidents. While the immediate focus is on preparedness and safety, the duration of the severe weather conditions remains to be confirmed. Travelers currently on the island should maintain contact with their accommodation providers and follow all instructions issued by local officials to ensure their safety during this period of heightened environmental risk.
