(Bangkok, 19th) – The Thai Meteorological Department has issued a weather forecast for April 19 to 24, indicating that many areas nationwide will experience severe convective weather, accompanied by high temperatures, thunderstorms, and localized hail. The public is urged to remain vigilant and take precautionary measures.
The forecast shows that from April 19 to 20, upper regions such as northern, northeastern, and central Thailand will be affected by summer storms, bringing thunderstorms, strong winds, and localized hail, with some regions also experiencing lightning strikes. The Meteorological Department stated that this weather pattern is mainly due to a high pressure system or cold air mass descending from China. As it extends to the South China Sea, it strengthens the southerly and southeasterly winds over the upper regions, intensifying weather instability. Local temperatures will remain hot to extremely hot.
From April 21 to 22, rainfall in the upper regions will decrease significantly, with thunderstorms only in some areas, while daytime temperatures will still remain high. The department explained that this is because the southerly and southeasterly winds affecting the northeast and eastern regions will gradually weaken.
However, from April 23 to 24, another high pressure system or cold air mass from China will again move southward, spreading to the South China Sea and northeastern Thailand. The upper regions will once again face summer storms, including thunderstorms, strong winds, and localized hail, which may be accompanied by lightning. The weather will remain hot.
As for the southern region, from April 19 to 22, with the strengthening of the southeasterly winds, rain in the Gulf of Thailand and southern regions will become more frequent. By April 23 to 24, as the wind weakens, rainfall will decrease.
Sea conditions: Waves will reach about 1 meter high in the Gulf of Thailand and Andaman Sea, possibly exceeding 2 meters during thunderstorms.
The Meteorological Department advises that, with the current hot weather, everyone nationwide should take care to prevent heatstroke and avoid extended outdoor activities. Those working at sea should steer clear of thunderstorm areas from April 19 to 20 and April 23 to 24.
In addition, residents in the upper regions should be wary of sudden storms and avoid staying in open areas, under large trees, or near unstable structures. Farmers are advised to reinforce fruit trees and take protective measures in advance to minimize damage to crops and livestock, and pay attention to the health effects of changing weather.
