Another strong high pressure has moved down and is expected to blanket upper Thailand until Dec 31, according to a forecast by the Meteorological Department.

This is likely to cause cold spells, as well as windy days, with a decrease of temperatures by 2-4°C. People should keep warm due to the change of weather conditions, it said.

A cold spell reportedly began to cover the upper North on Wednesday morning, causing the average minimum temperature to fall to about 15°C.

The cold weather is expected to extend to cover the North and lower Northeast from tomorrow.

As a strong northeast monsoon has prevailed over the Gulf and the South, more rain with some heavy rain is expected in the lower South.

The strong winds will cause high waves of up to 2-3 metres in the Gulf. All vessels should proceed with caution, and small boats keep ashore during Dec 28-31.

In Bangkok and nearby provinces, the temperatures will drop by 1-2°C from Wednesday, with a strong wind. The minimum temperature is expected to be 21°C and maximum temperature 32°C.
