Heavy rainfall forecast for 45 Thai provinces, flash flood alert
Heavy rainfall warnings have been issued for 45 provinces in Thailand, with potential hazards including flash floods and runoff. The Meteorological Department of Thailand (TMD) advises caution, particularly in hilly areas and near waterways, and urges sailors to avoid stormy seas.
The TMD forecasted the weather for the next 24 hours, predicting heavy rainfall in the northern, northeastern, and eastern regions. Residents in these areas are advised to remain vigilant due to the risk of flash floods and water runoff, especially in hilly terrains and low-lying regions.
A moderate monsoon trough is currently passing through the upper northern region of Thailand and northern Laos, extending into a low-pressure area over northern Vietnam and the Gulf of Tonkin. This, combined with a moderate southwesterly monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand, is expected to cause significant rainfall and strong winds.
The Andaman Sea and the Gulf of Thailand will experience waves approximately 1 metre high, with stormy areas seeing waves between 1 and 2 metres high. The TMD advises sailors to avoid navigating through stormy conditions.
Meanwhile, Typhoon Omphul is centred southeast of Japan. Travellers to this region are urged to check weather conditions before departure.
