Heavy rain forecast for Sunday as strong monsoon persists: TMD

Isolated heavy rain is likely in the Northeast, Central, Eastern, and Southern regions of Thailand, with very heavy rainfall expected in parts of the North on Sunday, according to the Thai Meteorological Department (TMD).

The monsoon trough lies across the upper North, Laos, and northern Vietnam, while a low-pressure cell covers the upper North. Meanwhile, a rather strong southwesterly monsoon continues to prevail over the Andaman Sea, Thailand, and the Gulf.

Residents in affected areas are advised to be cautious of heavy to very heavy rainfall, which may cause flash floods and overflowing, particularly near foothills and low-lying areas.Winds over the upper Andaman Sea are expected to generate waves of two to three metres, rising above three metres in areas experiencing thunderstorms. In the lower Andaman Sea, waves will reach about two metres, and exceed this during thunderstorms.

All vessels in the Andaman Sea and the Gulf should proceed with caution and avoid thunderstorms. Small boats in the upper Andaman Sea are advised to remain ashore.Today’s weather forecast
