The upper part of Thailand will experience a temperature rise of 1-2 °C on Tuesday as the high-pressure system covering upper Thailand and the South China Sea weakens, the Thai Meteorological Department said on Tuesday.
Cool to cold weather is forecast in the North and the Northeast with possible frost on the mountaintops, while cool mornings will continue in the Central region, including the Bangkok metropolitan area, the East and the upper South, it said.
The department urged people to take care of their health due to cold weather and be cautious of fire hazards caused by dry air. Motorists should take more caution in areas with poor visibility.
Meanwhile, the northeast monsoon prevailing over the Gulf and the South is weakening, resulting in reduced rainfall and isolated thunderstorms in the lower South.
Waves in the Gulf of Thailand will rise to 1-2 metres in height and over 2 metres in thunderstorms. All ships should proceed with caution and avoid areas with storms, the department warned.
