The Thailand Meteorological Department said on Thursday (December 30) that the rather strong high-pressure system from China covers upper Thailand. Cool to cold weather and strong winds are forecast in the areas with a decrease in temperature by 1-2 °C.

Mountaintops in the North and the Northeast are cold to very cold with temperature ranging from 4 to 14 °C. Meanwhile, the westerly trough that moves pass the upper North brings isolated thundershowers to the region. People should take care of their health due to variable weather.
The Department also mentioned that the strengthening northeast monsoon prevails across the Gulf of Thailand and the South. Thundershowers and isolated heavy rains are possible for the lower South.
Waves in the Gulf are about 2 meters high and over 2 meters during thundershowers. People in the lower South should beware of the severe condition and rain accumulation that may cause flash flood and overflows. All ships should proceed with caution and keep off thundershowers.
