Severe weather alert: Heavy rain and strong winds expected nationwide, with flash floods in the South
Thailand's Meteorological Department warns of heavy rain, gusty winds, and flash floods, especially in the South, due to a weather disturbance
The Thai Meteorological Department has issued a weather warning, "Severe weather expected across Thailand" (No. 9, 58/2569), regarding unsettled weather conditions that will affect the country. The disturbance is expected to cause heavy rain, strong winds, and flash floods, especially in the South. These conditions will continue until May 10, 2026.
Weather Situation:
The current weather disturbance is caused by a high-pressure system or cold air mass from China, which is spreading across Northeast Thailand and the South China Sea. This, combined with southerly winds bringing moisture from the Gulf of Thailand and the South China Sea, is causing widespread rainfall and gusty winds across the country. The unsettled weather will bring some relief from the hot temperatures, but it will also create hazardous conditions.
