Thai Meteorological Department: Heavy Continuous Rain Today in 2 Regions Affecting 70% of Areas, Bangkok 60% Coverage—Flood and Flash Flood Warnings Issued
Heavy rainfall is expected today across western and eastern Thailand with 70% area coverage, while Bangkok faces 60% thunderstorm potential. Flash flood warnings are in effect for foothill areas and low-lying zones as the southwest monsoon
The Thai Meteorological Department warns of heavy continuous rainfall today affecting 70% of areas across two regions, with Bangkok experiencing 60% coverage. The 24-hour forecast from today at 6:00 AM to tomorrow at 6:00 AM shows nationwide rainfall will decrease, though heavy showers will continue mainly in western and eastern Thailand due to the weakening southwest monsoon combined with a low-pressure system over northern Vietnam.
Public warnings are in place for dangers from heavy rainfall and accumulated precipitation, which may cause flash flooding and runoff—particularly in foothill areas near waterways and low-lying zones. People are advised to monitor their health during weather changes. Wave conditions in the Andaman Sea and Gulf of Thailand are weakening, with the upper Andaman Sea at approximately 2 meters, while the lower Andaman and upper Gulf show waves of 1-2 meters. Areas with thunderstorms may experience waves exceeding 2 meters. Mariners are urged to exercise caution and avoid thunderstorm zones.
