TMD Warns Heavy Rain, Flash Floods for Southern Thailand
The Thai Meteorological Department has issued a severe weather warning for heavy to very heavy rainfall across Southern Thailand from November 10-13, with specific provinces listed for each day. The alert includes risks of flash floods, mudslides, and waves exceeding two meters in the Andaman Sea and Gulf of Thailand. Residents and mariners are urged to exercise caution, while upper Thailand faces cooler temperatures and strong winds from a Chinese high-pressure system.
The Thai Meteorological Department (TMD) issued Announcement No. 4 on November 10, 2026, at 05:00, warning of heavy to very heavy rain in Southern Thailand from November 10-13, 2026 (Announcement 302/2569). During this period, Southern Thailand will experience heavy to very heavy rainfall in some areas. The public is warned of dangers from continuous accumulated rainfall, which may cause flash floods and mudslides, particularly in foothill areas near waterways and low-lying zones.
For wind-driven waves in the Andaman Sea and Gulf of Thailand, areas with thundershowers will see waves higher than two meters. Mariners in the Gulf of Thailand and Andaman Sea should navigate with caution and avoid areas with thunderstorms.
In upper Thailand, there will be isolated rain with cooler temperatures and strong winds. However, the upper North will see thundershowers and gusty winds in some areas due to a high-pressure system or cold air mass from China spreading to cover Thailand. The public is advised to maintain 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 covering upper Thailand and the South China Sea, combined with a westerly wind wave moving through Myanmar and upper Thailand, while the moderate northeast monsoon prevails over the Gulf of Thailand, Southern Thailand, and the Andaman Sea.
For safety and to reduce potential impacts, the public is asked to plan daily life and travel during this period carefully. The public is urged to continuously follow announcements from the Thai Meteorological Department. Information can be tracked at the TMD website https://tmd.go.th or by calling 0-2399-4012-13 and 1182, available 24 hours.
The next announcement will be issued on November 10, 2026, at 17:00.
