TMD Warns of Heavy Rain, Flood Risk in South Thailand Nov 10-13

The Thai Meteorological Department issued Announcement No. 5 warning of heavy to very heavy rain in Southern Thailand, listing affected provinces and urging the public to beware of flash floods and mudslides. On November 10, 2026, the department announced heavy to very heavy rain in the South effective November 10-13, 2026 (Announcement No. 5, 303/2026). During November 10-13, 2026, Southern Thailand will experience heavy to very heavy rain in some areas. Residents are warned of dangers from continuous accumulated rainfall which may cause flash floods and mudslides, especially in foothill areas near waterways and lowlands. For wind waves in the Andaman Sea and Gulf of Thailand, conditions will strengthen. The lower Gulf will see waves 2-3 meters high, while areas with thundershowers will have waves exceeding 3 meters. Mariners in the Gulf and Andaman Sea should navigate with caution and avoid thundershower areas. Small boats in the lower Gulf should refrain from leaving shore during this period. Nationwide, temperatures will drop with strong winds, except the upper North which will see thundershowers and strong gusts in some areas due to a high-pressure system or cold air mass from China spreading over Thailand. People should maintain their health due to the colder weather, and farmers should prevent potential damage to agricultural crops. This is because a fairly strong high-pressure system or cold air mass from China is spreading over upper Thailand and the South China Sea, combined with a westerly wind wave moving through Myanmar and northern Thailand, while the northeast monsoon prevails over the Gulf, South, and Andaman Sea. For safety and to reduce potential impacts, the public is asked to plan daily activities and travel carefully during this period. The public should continuously monitor announcements from the Thai Meteorological Department, with information available at the TMD website https://tmd.go.th or at 0-2399-4012-13 and 1182, 24 hours a day.
