Incoming monsoon triggers warnings for torrential rainfalls in 33 Thai provinces, including Bangkok

The Meteorological Department today warns of relentless storms resulting in heavy rainfall mainly affecting northern Thailand. Thirty-three provinces, including Bangkok, where 60% of the area has been heavily afflicted calls for residents to be cautious in these areas. The phenomenon could result in flash floods and outlandish forest water flows.

The monsoon winds blowing heavily from the southwest continue to blanket the upper Andaman Sea and upper Thailand, combined with a low-pressure trough covering upper Vietnam. In effect, the sea waves in the upper Andaman Sea rise to about 2 metres in height, while it varies between 1 to 2 metres in the northern Gulf of Thailand. Maritime dwellers are thus urged to navigate with caution and avoid areas with thunderstorms at this time.
