TMD Warns Heavy Rain, High Waves for Southern Thailand
TMD warns of heavy to very heavy rain across Southern Thailand from Nov 9–13, with flash flood and mudslide risks, and Andaman Sea waves exceeding two meters.
The Thai Meteorological Department warns of heavy to very heavy rain in Southern Thailand effective November 9–13, 2026 (Announcement No. 3, dated November 9, 2026). During this period, the South will continue to experience persistent rain with heavy downpours in many areas and very heavy rain in some locations. The public is cautioned against the dangers of accumulated rainfall, which may trigger flash floods and mudslides, especially in foothill areas near waterways and low-lying basins. In the Andaman Sea and Gulf of Thailand, waves in thunderstorm areas will exceed two meters. Mariners in the Gulf and Andaman should navigate with caution and avoid sailing in thunderstorm zones. For upper Thailand, cooler weather with strong winds is forecast. Temperatures in the North and Northeast will drop 3–5°C, while the Central region, Bangkok and its vicinity, and the East will see a 1–3°C decrease as a high-pressure system or cold air mass from China spreads over the country. The public should look after their health in the cooler conditions, and farmers should protect crops from potential damage. The strong high-pressure system from China covering upper Thailand and the South China Sea will intensify the northeast monsoon over Thailand and the Gulf. For safety and to minimize impacts, the public is urged to plan daily activities and travel carefully during this period and to follow TMD announcements continuously. Information is available at tmd.go.th or the 24-hour hotlines 0-2399-4012-13 and 1182. Announced November 9, 2026 at 17:00. Next announcement: November 10, 2026 at 05:00.
