Heavy rain warning issued for North, East and South

Thailand’s weather office has warned of heavy rain in the North, East and South, with Bangkok forecast to see thunderstorms over 60% of the area

The Thai Meteorological Department has warned people in the North, East and South to prepare for heavy rain in some areas over the next 24 hours, while Bangkok and surrounding provinces are forecast to see thunderstorms across 60% of the area.

The forecast, issued at 5pm on Saturday, June 13, said a moderate southwesterly monsoon was covering the Andaman Sea, Thailand and the Gulf of Thailand. A low-pressure cell was also covering upper Myanmar.

The department said these conditions would bring heavy rain to parts of the North, East and South. People in affected areas were advised to watch for danger from heavy rainfall and accumulated rain, which could cause flash floods and forest run-off, particularly in risk areas near waterways and in low-lying communities.
