Heavy rain warning across 25 provinces in Thailand, southern region hit hardest

The Thailand Meteorological Department (TMD) issued a warning for continued heavy rain across 25 provinces today. Southern Thailand is being hit hardest, with 70% of the region experiencing heavy rainfall.

The public has been cautioned to be alert for dangers, including flash floods and forest runoff, particularly in areas on hill slopes near waterways and lowlands.

The high air pressure covering the upper part of Thailand is weakening, and easterly winds are pervading the country, the Gulf of Thailand, and the Andaman Sea. This pattern is causing fog in the morning in the upper part of Thailand and an increase in rain.

As the South continues to receive heavy rain in some areas, residents in the southern region are advised to beware of heavy rainfall and accumulated rain, which can cause sudden flash floods and forest runoff, especially in areas near hill slopes, lowland areas, and areas where water flows through.

Additionally, precautions need to be taken when travelling through areas with thunderstorms. In the Gulf of Thailand and the Andaman Sea, waves are about 1 metre high, and in areas with thunderstorms, the waves are more than 2 metres high. Boaters are urged to navigate with caution and avoid sailing in thunderstorm areas.
