Thunderstorms and heavy rain forecast for 50 Thai provinces

The Meteorological Department of Thailand (TMD) issued a weather forecast warning for thunderstorms across 50 provinces, with heavy rain expected in Bangkok from afternoon to evening. Citizens are urged to be cautious of flash floods and sudden water surges.

The weather forecast for the next 24 hours predicts a medium-strength monsoon trough over the upper northern and northeastern regions, extending into a low-pressure area over northern Vietnam and the Gulf of Tonkin.

Additionally, the southwest monsoon continues to cover the Andaman Sea, Thailand, and the Gulf of Thailand. This weather pattern causes heavy rainfall in the northern, upper northeastern, and central regions, including Bangkok and its vicinity, the eastern, and the southern regions.

The TMD today warned that 49 provinces across four regions, including Bangkok, would experience severe weather conditions, with 70% of the area expected to receive heavy rain.

Residents in these regions should be wary of accumulated rainfall, which could lead to flash floods and water surges, especially in hilly areas, near water flow routes, and low-lying areas.

In the Andaman Sea and the Gulf of Thailand, waves are expected to reach about 1 metre and over 2 metres in areas with thunderstorms. Mariners should avoid navigating in stormy regions.

Meanwhile, Typhoon Ompil is centred east of Japan and will not affect Thailand’s weather. Travellers to the affected areas should check the weather forecast before their journey.

The northern region will experience thunderstorms in 70% of the area, with heavy rainfall in Mae Hong Son, Chiang Mai, Chiang Rai, Lampang, Phayao, Nan, Phrae, Tak, Uttaradit, Phitsanulok, and Phetchabun. Temperatures will range from 23 to 26°C to 32 to 35°C, with southwest winds at 5 to 15 kilometres per hour.
