Meteorology Bureau Issues Final Heavy Rain Warning

The Thai Meteorology Department issued its 18th warning on 28 September regarding heavy to very heavy rainfall across Thailand, stating this is the final bulletin for this event. The western and lower northern regions, western central areas, and the northeast will continue to experience heavy downpours, while other regions will see reduced rainfall but isolated heavy showers remain possible. A low-pressure system has moved into the Mataban Gulf while a moderately strong southwest monsoon continues to blanket the Andaman Sea, southern Thailand, and the Gulf of Thailand.

Residents of the north, central, and northeast regions are urged to exercise caution against heavy rain and accumulated rainfall over the next day, which may cause flash flooding particularly in foothill areas near water channels and in low-lying zones. Residents should avoid routes prone to repeated flooding, especially in low-lying areas that may experience brief inundation. The department has identified 40 provinces with heavy rain.

Waves in the Andaman Sea and Gulf of Thailand are moderately strong, with the upper gulf and northern Andaman reaching 2-3 metres, or higher than 3 metres during thunderstorms. The lower gulf and southern Andaman are seeing approximately 2-metre waves, or higher than 2 metres in thunderstorm areas. Fishermen should navigate with caution and avoid thunderstorm zones. Small boats in the upper gulf and northern Andaman should remain ashore until 28 September 2026.

The public is advised to plan activities and travel carefully during this period. Updates are available at the Meteorology Department website (http://www.tmd.go.th) or by telephone at 0-2399-4012-13 and 1182 around the clock. This is the final bulletin for this weather event.
