Summer storm hits Thailand with heavy rain and hail
The Thai Meteorological Department (TMD) issued a forecast warning of a summer storm affecting 58 provinces with heavy rain, strong winds, hail, and possible lightning. The announcement yesterday, April 28, to Thursday, May 1, with regions in northern and northeastern Thailand expected to be affected.
The TMD’s 24-hour forecast indicates that upper Thailand will experience summer storms, characterised by thunderstorms, gusty winds, hail, and heavy rain in some areas. Residents in affected areas are advised to stay cautious and avoid open spaces, large trees, unstable structures, and billboards.
Farmers are urged to reinforce fruit trees and prepare to mitigate potential damage to crops and livestock. Additionally, attention to health during these changing weather conditions is recommended. A 15-day rain forecast indicates the need for vigilance due to the summer storm.
This weather phenomenon results from a moderate high-pressure system from China that covers Vietnam and the South China Sea, causing southeasterly and southwesterly winds to affect upper Thailand. While the region is experiencing hot to very hot weather, a western wind wave from Myanmar is moving into northern Thailand.
Meanwhile, the southern region will have heavy rain due to southeasterly winds over the Gulf of Thailand, the southern region, and the Andaman Sea. Mariners are advised to avoid sailing in areas with thunderstorms, where waves can exceed 2 metres.
Air quality, affected by dust and haze in northern and northeastern Thailand, remains moderate to high, with a tendency to stabilise or decrease due to possible rainfall.
In northern Thailand, 60% of the area will have thunderstorms with gusty winds, hail, and heavy rain, including Mae Hong Son, Chiang Mai, and Chiang Rai. Temperatures range from 20-24°C minimum to 33-39°C maximum, with southwesterly winds at 5-15 km/h.
In the northeast, similar conditions are expected with thunderstorms covering 60% of the area, especially in Loei, Nong Khai, and Bueng Kan, with temperatures ranging from 21-25°C minimum to 37-39°C maximum. Southeasterly winds will prevail at 10-20 km/h.
The central region will see hot to very hot weather with thunderstorms in 60% of the area, including Nakhon Sawan and Uthai Thani. Temperatures will be 24-26°C minimum to 38-40°C maximum, with southerly winds at 10-20 km/h.
Eastern provinces will experience thunderstorms in 30% of the area, notably Nakhon Nayok and Prachin Buri, with temperatures between 25-27°C minimum and 34-38°C maximum. Southeasterly winds at 10-30 km/h will occur, with sea waves below 1 metre and exceeding 2 metres during storms.
The southern region (east coast) will have thunderstorms in 40% of the area, mainly in Chumphon and Surat Thani. Temperatures will range from 23-26°C minimum to 33-37°C maximum, and southeasterly winds will be 10-30 km/h. Sea conditions will be similar to the east.
