The Thai Meteorological Department (TMD) issued a severe weather warning for the entire country today, with heavy rain and thunderstorms expected in 32 provinces. Bangkok could see a chance of 70% rainfall from the afternoon till dusk, posing a potential risk of flash floods. The department also advises boat operators to exercise caution, especially in the Andaman Sea and Gulf of Thailand, where storms can result in waves rising to 1 to 2 metres.
The weather system is being driven by a monsoon trough passing through Myanmar and Laos, creating a low-pressure area over northern Vietnam. Meanwhile, the southwest monsoon continues to prevail over the Andaman Sea, Thailand and the Gulf of Thailand. In such conditions, Thailand is likely to experience scattered thunderstorms, with heavy rain in some areas of the northeastern, eastern and southern regions. Residents in these areas are advised to remain vigilant for potential threats from heavy and accumulated rainfall, which may lead to flash floods.
In the Andaman Sea and the Gulf of Thailand, the wind-generated waves are expected to reach an average height of 1 metre. However, in areas with thunderstorms, waves could reach heights between 1 to 2 metres. Mariners are urged to navigate with caution and avoid entering storm-affected areas.
