Cold air brings storms and cooler weather to Thailand
A new cold air mass is spreading across Thailand, bringing thunderstorms and cooler temperatures. The Thai Meteorological Department (TMD) warns of adverse conditions affecting 32 provinces, with the central region, including Bangkok, expected to experience the most severe impact.
A fresh, moderately strong high-pressure system from China has reached Vietnam’s northern region and the South China Sea. This weather pattern is anticipated to extend further into northeastern Thailand today.
The initial effect will be thunderstorms in upper Thailand, followed by a temperature drop, resulting in cool and windy conditions. In the northeast, temperatures are expected to decrease by 2 to 4 degrees Celsius, while the northern, central, eastern regions, and Bangkok will see a reduction of 1 to 3 degrees Celsius.
TMD advises residents in affected areas to take care of their health due to the changing weather conditions. Caution is also recommended when travelling in foggy areas, and farmers are advised to prepare for potential agricultural damage due to the expected rainfall.
The prevailing northeast monsoon, though weak, is affecting the Gulf of Thailand and the southern region, causing thunderstorms, with some areas experiencing heavy rain.
In the Gulf of Thailand and the Andaman Sea, waves are generally low at under 1 metre, but can exceed 2 metres during thunderstorms. Mariners are advised to avoid sailing in stormy areas.
