The Meteorological Department forecasts for the next 24 hours that rainfall across Thailand will decrease, though heavy rain will persist in parts of the northeastern and eastern regions due to moderate southwest monsoon winds covering the Andaman Sea, Thailand, and the Gulf of Thailand. A low-pressure system sits over northern Vietnam.
Residents across Thailand's upper regions should be alert to dangers from heavy and accumulated rainfall, which may trigger sudden flooding and flash floods, especially in foothill areas near water channels and low-lying zones.
Wave conditions in the upper Andaman Sea and upper Gulf of Thailand are moderate, with waves 1-2 meters high. The lower Andaman Sea has waves around 1 meter, but thunderstorm areas may see waves exceeding 2 meters. Fishermen should exercise caution and avoid thunderstorm zones.
