Thailand's Meteorological Department issued a heavy rain alert for 32 provinces on August 3, warning of flash floods and dangerous sea conditions across the country as monsoon troughs and a low-pressure system bring widespread thunderstorms
The Thai Meteorological Department issued a weather alert on August 3, 2025, forecasting continued heavy rain across northern Thailand over the next 24 hours due to monsoon troughs passing over the northern region and northern Laos, combined with a low-pressure system near the Vietnamese coast and moderate southwest monsoon winds affecting the Andaman Sea, Thailand, and the Gulf of Thailand.
The department warned the public to be cautious of heavy rainfall and accumulated water that may cause flash floods and flash floods, particularly in sloped areas near waterways and low-lying areas. The Andaman Sea's northern region is expected to see waves 1–2 meters high, while the southern Andaman Sea and Gulf of Thailand will experience approximately 1-meter waves, with thunderstorm areas seeing waves exceeding 2 meters. Fishermen are urged to exercise caution and avoid sailing in thunderstorm zones.
