Thailand Weather Dept Issues Heavy Rain Warning Oct 11-13
Thailand’s Meteorological Department issued a heavy rain warning for October 11‑13, forecasting thunderstorms, strong winds, hail, and possible lightning across much of the country. The alert specifies affected regions each day, with the South facing rain on all three days and the North, Central, and East affected on the first day. Authorities urged the public to prepare for flash floods, landslides, and rough seas, and to monitor official updates.
On October 11, 2026, the Thai Meteorological Department announced Warning No. 9, stating that from October 11 to 13 the country will experience unstable weather characterized by thunderstorms, strong gusts, hail, and localized heavy to very heavy rain, with possible lightning. The impacts are expected in the lower North, Central region including Bangkok and its vicinity, the East, and the South on October 11; limited to the South on October 12; and again only the South on October 13. The pattern results from a cold high-pressure system moving down from China, easterly winds carrying moisture from the South China Sea, and the ongoing southwest monsoon over the Andaman Sea, with a monsoon trough extending across the south. The department warned that 39 provinces could see heavy rainfall, raising risks of sudden flash floods and overflowing streams, especially in hilly and low-lying areas, and advised people to avoid open spaces, large trees, and insecure billboards; mariners in the Gulf of Thailand and the Andaman Sea should expect waves over two meters and steer clear of thunderstorm zones, checking routes and proceeding with caution. The public is urged to follow updates via the department’s website or hotline, with a follow‑up bulletin scheduled for the same day at 17:00.
