Thailand braces for heavy rain across 35 provinces

The Thai Meteorological Department (TMD) issued a weather warning for 35 provinces across Thailand, advising residents to brace for continuous heavy rainfall. Bangkok is expected to experience intense showers covering 60% of the area.

Citizens are urged to be cautious of accumulated rainfall and potential hazards. The sea is reported to have waves exceeding 2 metres.

The TMD forecasts weather conditions for the next 24 hours, indicating that the southwest monsoon is sweeping over the Andaman Sea, Thailand, and the Gulf of Thailand. This weather pattern, combined with a low-pressure system over northern Vietnam, is expected to bring thunderstorms across the country, with particularly heavy rain in the upper northeastern region and the western coast of the southern region.

Residents in these areas should exercise caution due to the heavy and accumulated rainfall and be extra careful when travelling through thunderstorm-prone zones.

The sea conditions in the Andaman Sea and the Gulf of Thailand are reported to be moderate. The upper Andaman Sea will experience waves 1 to 2 metres high, and areas with thunderstorms will see waves exceeding 2 metres.

The lower Andaman Sea and the Gulf of Thailand will have waves about 1 metre high, with higher waves in thunderstorm areas. Mariners are advised to navigate with care and avoid sailing in regions affected by thunderstorms.
