BANGKOK, Thailand – The Meteorological Department reports heavy rain in parts of Northern, Upper Northeastern, and Southern Thailand, with potential flash floods and landslides. In Bangkok and surrounding areas, thunderstorms are expected in 60% of the region.
The Meteorological Department forecasts for the next 24 hours show a monsoon trough extending over the upper northern region of Thailand and upper Laos, connected to a low-pressure area over northern Vietnam. This, combined with southeasterly and southwesterly winds affecting the upper northern and northeastern regions, and the southwest monsoon continuing to cover the Andaman Sea, Thailand, and the Gulf of Thailand, will lead to heavy rainfall in some parts of the north, upper northeast, and southern regions.
Residents in these areas are advised to be cautious of heavy rain and accumulated rainfall, which may cause flash floods and landslides, particularly in foothills, near waterways, and in low-lying areas.
For the upper Andaman Sea, waves will reach heights of 1-2 meters, and in areas experiencing thunderstorms, waves may exceed 2 meters. Seafarers are advised to avoid sailing in stormy regions.
