The mountaintops in the North and the Northeast would experience cold to very cold conditions. The public in these regions should take care of their health due to the cold weather, the department advised.
The department also warned people in the North and the upper South to be cautious about fire hazards triggered by dry conditions and strong winds.
Isolated heavy rains are predicted for the lower South, with waves in the Gulf of Thailand expected to reach above four metres high, and three metres high in the Andaman Sea.
The department advised all ships to proceed with caution and keep off thundershower areas.
“People along the coast in the Gulf and the Andaman Sea should beware of inshore surges,” the department said, adding that boats should be kept ashore until Monday (January 13).
