Monsoon mayhem: TMD forecasts heavy rains for 51 provinces, including Bangkok

The Thai Meteorological Department issued a warning for heavy rains caused by monsoons affecting 51 provinces across the country, including Bangkok, with 70% of the areas expected to be hit hard. The warning, issued today, September 18, forecasts continuous rain for the next 24 hours due to a moderate monsoon trough passing through the northern and upper northeastern regions.

The monsoon is entering a low-pressure area along the coast of northern Vietnam combined with a moderate southwest monsoon that is covering the Andaman Sea, the lower northeastern region, the central region, the eastern region, the southern region, and the Gulf of Thailand. This will result in continuous rainfall, with heavy rainfalls in some areas of the northern, northeastern and central regions including Bangkok and its vicinity.

The public is urged to be cautious of heavy rainfall and accumulated rain which could lead to flash floods and forest runoff, particularly in areas near mountain slopes, waterways, and low-lying areas. Also, precautions should be taken when travelling through areas with thunderstorms.

In the Andaman Sea and the Gulf of Thailand, the sea is moderate. For the Andaman Sea from the provinces of Ranong upwards, waves are 1 to 2 metres high and more than 2 metres high in areas with thunderstorms. For the Andaman Sea from Phang Nga downwards and the Gulf of Thailand, waves are about 1 metre high and 1 to 2 metres high in areas with thunderstorms. It is advised that sailors in these areas navigate with caution and avoid sailing in areas with thunderstorms.
