The North and the Northeast regions will experience cool weather in the morning with less rain on Wednesday, the Thai Meteorological Department said this morning.
These conditions are due to the moderate to rather strong high-pressure system prevailing over the Northeast and the South China Sea while the easterly and southeasterly winds prevailing over the upper country are weakening, the department said.
It urged people in the upper country to take care of their health due to the changing weather, while farmers should take precautions to protect crops and animals from potential damage.
Meanwhile, northeast monsoon and easterly wind over the Gulf, the South and the Andaman Sea will bring isolated heavy rains to the South, the department said, urging residents to beware of flash floods and overflows, especially along the waterways, near foothills and lowlands.
Waves in the lower Gulf are 2-3 metres high and above 3 metres in thundershowers. All ships should proceed with caution and keep away from storms, the department warned.
