The Meteorological Department reports increased rainfall across Thailand, with heavy rain in some areas. The eastern region may experience very heavy rainfall in certain areas, so residents are advised to be cautious of sudden flooding and flash floods. In Bangkok and its vicinity, thunderstorms are expected in 70% of the area, with heavy rain in some places.
The 24-hour weather forecast indicates that the monsoon trough will shift over the upper northern region and upper Laos, moving into a low-pressure area over northern Vietnam and the Gulf of Tonkin. This, combined with moderate southwest monsoon winds covering the Andaman Sea, Thailand, and the Gulf of Thailand, will result in increased rainfall and heavy rain in some areas. In particular, very heavy rain is expected in parts of the eastern region. Residents in these areas should be cautious of heavy to very heavy rain and accumulated rainfall, which may lead to flash floods and water runoff, especially in mountainous areas near waterways and low-lying areas. Additionally, travelers should exercise caution when passing through areas experiencing thunderstorms.
In the upper Andaman Sea and upper Gulf of Thailand, waves are about 2 meters high. In the lower Andaman Sea and lower Gulf of Thailand, waves are 1-2 meters high, with waves over 2 meters high in areas with thunderstorms. Mariners in these areas are advised to navigate with caution and avoid sailing in areas with thunderstorms.
