"Meteorological Department" (Thai Meteorological Department) Issued the 5th warning of heavy to very heavy rain in Southern Thailand, advising the public to beware of dangers from continuous accumulated rainfall that may cause flash floods and flash flooding.
At 17:00 on 10 November 2026 GMT+7 Meteorological Department Issued an announcement regarding"Heavy to very heavy rain in Southern Thailand (effective from 10-13 November 2026)"The 5th announcement states that from 10 to 13 November 2026, Southern Thailand will experience heavy to very heavy rain in some areas. The public is advised to be cautious of continuous accumulated rainfall, which could cause flash floods and flash flooding, especially in hilly areas near waterways and lowlands.
Sea waves in the Andaman Sea and the Gulf of Thailand will strengthen, with waves reaching 2-3 meters in the lower Gulf of Thailand and over 3 meters in areas with thunderstorms. Fishermen in the Gulf of Thailand and Andaman Sea should navigate carefully and avoid sailing in thunderstorm areas. Small boats in the lower Gulf of Thailand are advised to stay ashore during this period.
Meanwhile, Thailand will experience cooler weather and strong winds, except in the upper northern region where thunderstorms and strong gusty winds may occur in some areas. This is due to a high-pressure area or fairly strong cold air mass from China spreading over Thailand. Residents are advised to take care of their health amid the cooler conditions, and farmers should protect their crops from potential damage.
This situation arises because a fairly strong high-pressure area or cold air mass from China is covering upper Thailand and the South China Sea, combined with a west wind wave moving across Myanmar and Northern Thailand, while a moderate northeast monsoon is prevailing over the Gulf of Thailand, Southern Thailand, and the Andaman Sea.
For safety and to minimize potential impacts, the public is urged to plan their activities and travel carefully during this period. Residents should continuously monitor announcements from the Meteorological Department and can access information at https://tmd.go.th or contact 0-2399-4012-13 and 1182, available 24 hours.
