Heavy rainfall warning issued for 37 Thai provinces: Public urged to remain vigilant

The Thailand Meteorological Department issued a warning for heavy rainfall across 37 provinces today, with the southern region experiencing heavy rain across 60% of its area. The public is urged to be cautious of potential dangers.

The weather forecast for the next 24 hours indicates a high pressure or cold air mass covering the upper part of Thailand and the South China Sea, which is starting to weaken. This condition is causing thunderstorms and heavy rainfall in the north of the country.

Meanwhile, the monsoon trough is passing over the southern region, coupled with a southwest monsoon still blowing over the Andaman Sea, the lower southern region, and the lower Gulf of Thailand, causing heavy rainfall in some areas in the south.

The public in the southern region is advised to be mindful of heavy and persistent rainfall, which could lead to flash floods and forest runoff, especially in areas near slopes, waterways, and low-lying areas. The Andaman Sea and the Gulf of Thailand are seeing waves of about 1 metre.

In stormy areas, the waves may be higher than 2 metres. Boat operators are advised to navigate with caution and avoid areas with thunderstorms.

The deep depression in the Bay of Bengal has strengthened into a cyclone Hamoon. It is expected to move into the upper Bay of Bengal and hit the coast of Bangladesh between October 25 and 26. This storm will not affect Thailand.
