The Thailand Meteorological Department has warned farmers in the North and the Northeast to beware of damage to crop from isolated thundershowers.


A weak high-pressure system covers upper Thailand and the South China Sea.

Mornings would be cool in the North and the Northeast, while the mountaintops would have cool to cold weather, the department said.

In the lower Northeast, the lower Central and the East, easterly winds prevail with humidity bringing isolated thundershowers.

In the South and the Gulf, the northeast monsoon becomes stronger with isolated heavy rain.

People in the South should beware of the severe weather conditions, the department said. On November 22-23, another moderate high-pressure system from China would extend to upper Thailand and the South China Sea. After isolated rain over the area initially, the temperature would start to fall.

In the South, the moderate northeast monsoon across the Gulf and the South will bring more rain and isolated heavy rain.
