Cold to very cold are forecast on mountaintops of the North and Northeast. Morning cool is forecast in the Central, East and upper South, including Bangkok and surrounding areas.
“People in the upper country should keep healthy due to variable weathers and beware of fire due to strong winds and dry air,” the department said.
The strong northeast monsoon could bring isolated thundershowers in the South (East coast), with waves expected to rise to three metres in the Gulf. Waves in the Andaman Sea, meanwhile, could rise to two metres in thundershowers.
“All ships in the Gulf and the Andaman Sea should proceed with caution and keep off thundershowers. Small boats in the lower Gulf keep ashore,” the department added.
