Thailand issues alert for 43C heatwave and severe summer storms
As Thailand grapples with a scorching heatwave, the Thai Meteorological Department (TMD) today issued an alert for extreme temperatures reaching up to 43 degrees Celsius, accompanied by summer storms, strong winds, and hail in some areas. The warning covers 45 provinces and advises the public to brace for potentially hazardous weather conditions.
The entire upper part of Thailand is experiencing a heatwave due to a low-pressure system caused by intense heat covering the area. This weather pattern is expected to result in generally hot to very hot conditions across the country, with partly cloudy skies during the daytime.
Residents are advised to take care of their health by avoiding prolonged outdoor activities during this hot period. Meanwhile, the southwestern and southeastern winds affecting the northern and northeastern regions could lead to summer storms in some areas, characterised by thunderstorms, strong winds, and occasional hail along with lightning strikes.
People in these regions are cautioned to stay clear of open fields, large trees, weak structures, and billboards, and to be vigilant when travelling through storm-hit areas. Farmers should prepare to protect their crops and livestock from potential damage during this period.
The southwestern and southeastern winds also affect the Andaman Sea, the southern region, and the Gulf of Thailand, bringing some thunderstorms to the south. Sea waves in the Andaman Sea are expected to be around 1 metre high, increasing beyond 1 metre in thunderstorm areas. Fishermen are advised to avoid sailing in these conditions. In the northern, northeastern, and central regions, moderate to high levels of dust particles and smoke haze are expected due to weak winds and poor air circulation.
For the 24-hour forecast from 6am today to 6am tomorrow, the northern region will generally experience hot to very hot weather with a 20% chance of thunderstorms, particularly in Mae Hong Son, Chiang Mai, Chiang Rai, Lampang, Phayao, Nan, Phrae, Uttaradit, Kamphaeng Phet, Tak, and Phetchabun.
