Heavy Rain Alert for South; Temperature Drop Up to 5°C in Upper Thailand
The Thai Meteorological Department has warned of heavy to very heavy rainfall across Southern Thailand from November 9-13, with flash flood and mudslide risks in multiple provinces. Simultaneously, a cold front from China will drop temperatures by up to 5°C in the Northeast and bring strong winds and high waves to the Andaman coast and Gulf of Thailand. Authorities urge the public, mariners, and farmers to take precautions and monitor updates.
The Thai Meteorological Department (TMD) issued Announcement No. 2 on November 9, 2026, warning of heavy to very heavy rain in Southern Thailand from November 9-13. Continuous downpours are expected across many southern provinces, with isolated very heavy rainfall. Residents are warned of dangers from accumulated rain that could trigger flash floods and mudslides, especially in foothill areas near waterways and low-lying zones.
In the Andaman Sea and Gulf of Thailand, waves are forecast to exceed two meters in areas with thunderstorms. Boat operators in both bodies of water should navigate with caution and avoid sailing in thunderstorm areas.
For upper Thailand, cooler weather and strong winds are expected. The Northeast will see temperatures drop 3-5°C, while the North, Central, Bangkok metropolitan area, and East will drop 1-3°C due to a strong high-pressure system from China extending over upper Thailand and the South China Sea. This will strengthen the easterly winds over Thailand and the Gulf.
The public is advised to take care of their health in the cooler conditions, and farmers should protect crops from potential damage. People should plan daily activities and travel carefully during this period. Continuous updates can be followed on the TMD website (https://www.tmd.go.th) or via hotlines 0-2399-4012-13 and 1182, available 24 hours. The next announcement will be issued at 5:00 PM on November 9, 2026.
