Heavy rainfall and flash flood warnings across Thailand

[webfact]

 

Heavy rainfall is expected across Thailand today, with over 60% coverage in all regions, including Bangkok. The Meteorological Department of Thailand (TMD) warned of potential flash floods and forest runoff due to the intense weather conditions.

 

The TMD forecasted that the southwest monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand is relatively strong. This, combined with a monsoon trough passing through northern Thailand and upper Laos, leading to a low-pressure area over northern Vietnam, is causing significant rainfall in many areas of the country.

 

Thailand will experience heavy to very heavy rainfall in several regions, particularly in the north, northeast, east, and western parts of the south.

Residents in these areas are advised to be cautious of the dangers posed by heavy and accumulated rainfall, which could result in sudden flooding and flash floods, especially in foothill areas near waterways and lowland regions. Additionally, caution while travelling in areas with thunderstorms is advised.

The upper Andaman Sea and upper Gulf of Thailand will have relatively strong wind waves, with waves expected to reach heights of 2 to 3 metres. In areas with thunderstorms, waves could exceed 3 metres.

 

The upper Gulf of Thailand will have waves of about 2 metres, and in areas with thunderstorms, waves will be higher than two metres. Mariners should exercise caution and avoid sailing in areas with thunderstorms, and it is recommended that small boats in the upper Andaman Sea remain ashore.
