TMD warns summer storms across 41 provinces; Bangkok rain chance 20%
Thailand’s Meteorological Department warns upper Thailand will see summer storms over the next 24 hours, bringing thunderstorms, gusty winds and possible lightning. The South will see more rain and stronger winds, with waves up to 1-2m in the lower Gulf.
The Thai Meteorological Department (TMD) forecast that over the next 24 hours, upper Thailand will experience summer storms, characterised by thunderstorms and strong, gusty winds in some areas, as well as possible lightning in certain locations. This is due to a high-pressure area or cold air mass from China covering the Northeast and the South China Sea, bringing southerly and south-easterly winds that carry moisture from the South China Sea and the Gulf of Thailand across upper Thailand. At the same time, upper Thailand remains hot, and a convergence line between south-westerly and south-easterly winds is affecting the lower Central region, the East, and the lower Northeast.
People in affected areas are advised to beware of summer storms and to avoid open spaces, staying under large trees, near buildings and unstable billboards. Farmers are advised to reinforce fruit trees and prepare to prevent damage to crops and livestock.
In the South, rainfall is expected to increase, with gusty winds in some places. This is because easterly and south-easterly winds over the Gulf of Thailand and the South are strengthening, while westerly winds are affecting the Andaman Sea. In the lower Gulf of Thailand, waves are expected at 1-2 metres, rising to more than 2 metres in thunderstorm areas. Mariners in the Gulf of Thailand and the Andaman Sea are advised to avoid sailing in areas with thunderstorms.
Dust and haze accumulation across the North, the Central region including Bangkok and surrounding areas, and the East is expected to be moderate to relatively high, due to weak-to-moderate ventilation.
