TMD warns summer storms to hit 47 provinces; Bangkok stays hot
Upper Thailand faces thunderstorms, strong gusty winds and hail, with heavy downpours and lightning possible in some areas, while dust and haze build up at moderate to high levels across several regions.
- The Thai Meteorological Department (TMD) has issued a warning for summer storms in upper Thailand, which will bring thunderstorms, strong winds, hail, and heavy rain to many provinces.
- The severe weather is caused by a high-pressure system from China meeting moisture-carrying winds from the South China Sea and the Gulf of Thailand.
- Despite the storms in other regions, Bangkok is forecast to remain hot and hazy, with maximum temperatures reaching 35-37°C, though there is a 20% chance of thunderstorms.
- Residents in affected areas are advised to take precautions by avoiding open spaces and unstable structures, while farmers are urged to protect crops and livestock.
The Thai Meteorological Department (TMD) forecasts that, over the next 24 hours, summer storms will affect upper Thailand, bringing thunderstorms, strong gusty winds, hail, and heavy rain in some areas, with possible lightning in some locations.
This is due to a high-pressure area or cool air mass from China covering the eastern part of the Northeast and the South China Sea, generating southerly and southeasterly winds that carry moisture from the South China Sea and the Gulf of Thailand over upper Thailand.
Meanwhile, hot weather persists across Thailand, and a westerly wind trough from Myanmar is moving in to cover the upper North.
People in affected areas are advised to beware of summer storms and to avoid staying in open areas, under large trees, near buildings, and under unstable billboards.
Farmers should reinforce fruit trees and prepare to prevent potential damage to agricultural produce and livestock.
Dust and haze across the North, Central region (including Bangkok and surrounding areas), and the East are at moderate to relatively high levels due to weak to moderate ventilation.
In the South, isolated thunderstorms are expected, as westerly winds cover the Andaman Sea and the South, while easterly winds cover the lower Gulf of Thailand.
In the lower Gulf of Thailand and the Andaman Sea, waves are around 1 metre, rising to over 2 metres in thunderstorm areas.
Mariners in the Gulf of Thailand and the Andaman Sea should avoid sailing in areas with thunderstorms.
Warning: Summer storms hit upper Thailand; thunderstorms, strong gusty winds, hail
Thai Meteorological Department Announcement No. 6 on summer storms in upper Thailand will remain in effect through March 6, 2026.
Upper Thailand will experience summer storms, characterised by thunderstorms, strong gusty winds, hail, and heavy rain in some areas, with possible lightning in some locations.
This is due to a high-pressure area or cool air mass from China covering the Northeast and the South China Sea, resulting in southerly and southeasterly winds bringing moisture from the South China Sea over the Northeast, the East, and the upper Gulf of Thailand.
At the same time, hot weather persists over upper Thailand, and a westerly wind trough from Myanmar is moving in to cover the upper North.
People in affected areas should beware of summer storms and avoid staying in open areas, under large trees, near buildings, and under unstable billboards.
Farmers should reinforce fruit trees and prepare to prevent potential damage to agricultural produce and livestock, and take care of their health during changing weather conditions.
The public is advised to follow updates from the Thai Meteorological Department.
