Thailand braces for a cold snap as a mass of cool air spreads across the country, bringing a drop in temperatures and strong winds. The Thai Meteorological Department (TMD) forecasts a temperature decrease of 1 to 3 degrees Celsius, with frost expected in some mountainous areas.
The latest weather forecast from the TMD reveals that a moderate high-pressure system from China has reached Thailand’s northeastern region. This system is expected to extend further, impacting the entire upper part of the country.
As a result, the northern and northeastern regions will experience cool to cold weather with strong winds, while the central region, including Bangkok, the eastern region, and upper southern region, will have cool mornings.
In the mountainous regions, the weather is anticipated to be very cold with some areas seeing frost. Locals are advised to take precautionary measures to protect their health due to the cold conditions. Moreover, the dry weather combined with strong winds could potentially lead to fire hazards, which should be watched out for.
The northeastern monsoon currently covering the Gulf of Thailand and the southern region is of moderate strength, resulting in scattered thunderstorms in the lower southern areas. The sea conditions in the Gulf of Thailand and the Andaman Sea are also moderate, with waves about 2 metres high in the lower Gulf and 1 to 2 metres high in the upper Gulf and Andaman Sea. In areas with thunderstorms, waves may exceed 2 metres. Mariners are advised to exercise caution and avoid sailing in areas experiencing thunderstorms.
In terms of air quality, the upper part of Thailand is experiencing moderate levels of PM2.5 dust particles. This is attributed to the current wind patterns and ventilation conditions, which are classified as moderate. Residents in these areas should remain cautious, particularly those with respiratory conditions.
