Weather update: Northern Thailand braces for chill as storms threaten the south

TheMeteorological Department of Thailand (TMD)forecasted another drop in temperatures across northern Thailand, with the weather ranging from cool to cold, particularly in the mountainous areas. Meanwhile, cloud cover has been observed in Bangkok.

In contrast, the southern region has been issued a warning for storm conditions affecting nine provinces.

A mass of cold air or high-pressure area continues to cover the northeastern region and the South China Sea, while westerly winds at higher altitudes sweep over the north. Consequently, the northern region experiences cool to cold weather in the mornings, with temperatures falling by 1-2 degrees Celsius. The northeastern, central, eastern and upper southern regions also experience cool mornings.

For the mountain peaks of the north, the weather ranges from cold to very cold, with the lowest temperatures between 6-11 degrees Celsius. Meanwhile, the peaks of the north-east experience cool to cold weather, with the lowest temperatures falling between 11-16 degrees Celsius. The public has been advised to maintain good health in the face of the continued cool weather during the mornings.

The northeastern monsoon over the lower Gulf of Thailand and the south has moderate strength, causing isolated thunderstorms in the lower southern region. Sea waves in the lower Gulf of Thailand are moderate with wave height about 1-2 metres.

In thunderstorm areas, wave height can be more than 2 metres. Boat operators are urged to proceed with caution and avoid sailing in thunderstorm areas.

Air quality

In terms of air quality, there is a moderate to rather high accumulation of dust particles/smoke fog in the lower northern region, central region including Bangkok and its vicinity, and the eastern region. This is due to weakened winds and poor ventilation.
