Rainfall hits 33 provinces: Southern Thailand in deep water

Heavy rainfall is expected in 33 provinces today, with the eastern and Andaman coast regions of southern Thailand experiencing particularly intense downpours. Other regions will continue to see rain, while Typhoon Yagi has made landfall in Vietnam and is expected to weaken.

The Meteorological Department of Thailand (TMD) forecasted severe weather conditions over the next 24 hours and heavy rain is predicted for the eastern and southern western coastal regions.

Additionally, the northeastern, eastern, and southern eastern coastal regions will see significant rainfall in some areas. Residents in these regions should be cautious of potential hazards such as flash floods and overflowing streams from accumulated rainfall.

Low-lying areas and slopes near watercourses are at particular risk, and there is also a warning for potential strong winds. This weather pattern is attributed to a relatively strong southwesterly monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand.

The Andaman Sea and the upper Gulf of Thailand will experience strong waves, with heights reaching 2 to 3 metres, and over 3 metres during thunderstorms. In the lower Gulf of Thailand, wave heights will range from 1 to 2 metres, exceeding 2 metres during storms.

Mariners in these areas should exercise caution and avoid sailing in stormy conditions, while small boats in the Andaman Sea and upper Gulf of Thailand are advised to stay ashore until tomorrow.
