Rapid changes in weather, thundershowers, heavy rains and gusts have been forecast for 36 provinces from September 22-26 by the Thailand Meteorological Department on Sunday (September 22).
The department attributed the weather conditions to a monsoon trough sitting over the Central, the East and the lower Northeast and a low pressure system over the South China Sea, while a moderate high-pressure system from China hung over the Northeast and the lower North.
The department said the sharp fall in temperature from Monday to Thursday would be caused by a moderate high-pressure system from China.
Residents of these areas should be cautious about weather fluctuations and take regular care of their health, the department said.
The affected areas are as follows:
Sunday (September 22): thundershowers, heavy to very heavy rains, winds and strong gusts.
