Thai weather warnings: 26 provinces face heavy rain, southern coast sees 2 metre waves

Rainfall is lessening nationwide today, but the Thai Meteorological Department warns that 26 provinces still face heavy rain and thunderstorm, affecting 40% of the area. The southern coastal region will experience waves higher than 2 metres during this time.

The department forecasted that a moderate southwesterly monsoon will cover the Andaman Sea in Thailand and the Gulf of Thailand, combined with a low-pressure area over Vietnam. This causes rainfall to decrease, but heavy downpours persist in some eastern regions of the country.

For the Andaman Sea and upper Gulf of Thailand, wind-induced waves stand at 1 to 2 metres, with thunderstorm locations experiencing over 2-metre high waves. The lower Andaman Sea and Gulf of Thailand have 1-metre high waves and 1 to 2 metre-high waves in thunderstorm areas. The coastal populace must take caution and avoid travelling in areas affected by thunderstorms, reported KhaoSod.

The northern region will experience 40% rain coverage, mainly in Mae Hong Son, Chiang Mai, Nan, Uttaradit, Tak, Phitsanulok, and Phetchabun provinces.
