Thailand Braces for Heavy Rain Across 47 Provinces
Heavy rain is expected across 47 Thai provinces over the next 24 hours, with risks of flash floods, river flooding, and landslides in hillside and low-lying areas, while waves in the Andaman Sea exceed 3 meters in thunderstorm zones.
The Thai Meteorological Department on September 20, 2024, forecasted heavy rain across Thailand for the next 24 hours. Residents must watch for dangers from heavy and accumulated rainfall that could cause sudden flash floods, river flooding, and landslides, especially in hillside and low-lying areas near water channels. Avoid routes prone to recurring flooding, particularly low-lying zones at risk of sudden waterlogging.
A high-pressure system from China covers the upper North and upper Northeast, while monsoon troughs cross the lower Central, upper South, and East regions. The southwest monsoon is moderately strong over the Andaman Sea, South, and Gulf of Thailand. Waves in the upper Andaman Sea are 2-3 meters high, exceeding 3 meters in thunderstorm zones. The lower Andaman Sea and upper Gulf see approximately 2-meter waves, exceeding 2 meters during thunderstorms. Boaters should exercise caution and avoid thunderstorm areas; small boats in the upper Andaman should stay ashore another day.
