Severe weather warning issued for Thailand: Heavy rain forecast across 44 provinces including 80% of Bangkok

Thailand Meteorological Department (TMD) issued a severe weather warning for heavy rainfall across 44 provinces, including an 80% area of Bangkok. The public is advised to remain alert for sudden flash floods and forest runoff, particularly in low-lying and mountainous regions close to waterways.

This severe weather warning comes due to the Monsoon trough passing over the central, lower northeastern, and eastern parts of the country, moving into a low-pressure area along the central Vietnamese coast.

Coupled with the southwestern monsoon prevailing over the Andaman Sea, Thailand, and the Gulf of Thailand, these conditions have resulted in severe weather warnings.

The TMD advised residents in the affected areas to be wary of accumulated rainfall that could potentially trigger flash floods and forest runoff, particularly in hillside areas near waterways and low-lying regions.

Extra precautions should be taken when travelling through areas with thunderstorms, and open areas, beneath large trees, and weak advertising signs should be avoided.

For the Andaman Sea and the Gulf of Thailand, waves are expected to reach heights of 1 to 2 metres, with areas experiencing thunderstorms seeing waves higher than 2 metres. Mariners are advised to proceed with caution and avoid areas affected by thunderstorms.
