Thailand Issues Final Warning for Heavy Rainfall and Storms Through October 25

The Thai Meteorological Department (TMD) has released its 13th and final weather advisory regarding severe weather conditions across Thailand. From October 23 to 25, 2026, the eastern and southern regions are expected to experience continuous heavy to very heavy rainfall. Meanwhile, the lower northern, lower northeastern, and central regions, including Bangkok and its surrounding areas, remain under a warning for thunderstorms and gusty winds.

This weather pattern is driven by a monsoon trough passing through the south, combined with a southwest monsoon over the lower Andaman Sea and high-pressure systems from China. Residents and travelers in these areas are advised to exercise extreme caution due to the risk of flash floods and forest runoff, particularly in low-lying areas and near mountain slopes.

Maritime conditions are also affected; the Andaman Sea and the Gulf of Thailand may see waves exceeding 3 meters in areas experiencing thunderstorms. Mariners are urged to navigate with caution and avoid sailing in storm-affected zones.

As this is the final advisory, the public is encouraged to monitor official updates via the TMD website (http://www.tmd.go.th) for any localized changes. Travelers should plan their itineraries carefully, as severe weather may disrupt transportation and outdoor activities. It remains to be confirmed how long the residual effects of these weather systems will persist beyond the October 25 deadline.
