Meteorological Department Forecasts Heavy Rain in Two Regions Tomorrow, Lists 45 At-Risk Provinces for Thunderstorms and Strong Winds
Thailand's Meteorological Department forecasts scattered thunderstorms and strong winds across 45 at-risk provinces through May 8, with the southern region expecting heavy rainfall and potential flooding.
On May 3, 2025, the Thai Meteorological Department issued a 24-hour weather forecast for upper Thailand, predicting hot afternoons with severe heat in parts of the northern and central regions. Thunderstorms and strong wind gusts are expected in some areas due to a heat-induced low-pressure system covering upper Thailand, combined with southwest and southeast winds bringing moisture. The public is advised to take health precautions by avoiding prolonged outdoor activities and remaining alert to dangers from thunderstorms and strong winds.
The southern region will experience scattered thunderstorms from easterly and southeast winds affecting the Gulf of Thailand, southern region, and Andaman Sea. Between May 6-8, rainfall will increase across the south with heavy rain in some areas caused by an easterly wind wave affecting the lower southern region. Residents are warned to prepare for potential flooding. Sea conditions in the Gulf and Andaman Sea show waves around 1 meter high, exceeding 2 meters in thunderstorm areas. Fishermen should exercise extra caution and avoid thunderstorm zones.
Air quality in upper Thailand remains good to moderate due to rainfall in scattered areas.
