The Meteorological Department has issued its second warning for 24-28 October, forecasting heavy to very heavy rain in southern Thailand with risks of flash floods. Meanwhile, from 25-27 October, upper Thailand will experience unstable weather conditions.

At 05:00 on 24 October 2026 GMT+7Meteorological DepartmentIssued its second announcement titled “Heavy to Very Heavy Rain in Southern Thailand and Unstable Weather in Upper Thailand” (effective from 24-28 October 2026).

From 24–28 October 2026, southern Thailand will experience continuous rainfall, with heavy rain in many areas and very heavy rain in some locations. The public should be cautious of accumulated rainfall that may cause flash floods and flash floods, especially in foothill areas near waterways and low-lying areas prone to waterlogging.

From 25–27 October 2026, upper Thailand will face unstable weather characterized by thunderstorms, strong gusty winds, and heavy rain in some places. This will initially affect the northeast region first, then spread.

The central region, including Bangkok and its vicinity, and the eastern region will be affected subsequently. People should beware of dangers from thunderstorms and strong winds, and avoid staying in open areas, under large trees, or near unstable billboards.

This is due to a high-pressure system or cold air mass from China spreading over upper Thailand and the South China Sea, causing easterly winds over Thailand and the Gulf of Thailand, while the monsoon trough passing through the south strengthens.

Waves in the Andaman Sea and the Gulf of Thailand in areas with thunderstorms will exceed 2 meters high. Fishermen in these waters should navigate with caution and avoid sailing in stormy areas.

For safety and to minimize impacts, the public is advised to plan their activities and travel cautiously during this period. Continuous monitoring of announcements from the Meteorological Department is recommended, with updates available on their website.http://www.tmd.go.thOr by calling 0-2399-4012-13 and 1182, available 24 hours.
