Heavy rains and flash floods warning for the South

Hot weather with isolated thundershowers and gusty winds are forecast for the North and the Central regions

An easterly wave moving pass the Gulf of Thailand and the South will bring more rainfall, gusty winds, and isolated heavy to very heavy rains to the South on Thursday, the Thai Meteorological Department said this morning.

It urged people in the South to be cautious of rain accumulation, which could cause flash floods and overflows, particularly along waterways, near foothills, and in lowland areas.

Waves in the lower Gulf and the Andaman Sea could rise to over 2 meters high in thundershowers, the department said, urging all ships to proceed with caution and avoid thundershowers.

In the upper country, hot weather with isolated thundershowers and gusty winds are forecast for the North and the Central regions, due to the influence of the moderate high-pressure system over the Northeast and the South China Sea and the prevailing southerly and southeasterly winds. 

The weather forecast for the next 24 hours is as follows:
