Another strong high-pressure system from China covers upper Thailand, bringing temperatures down by 2-3 degrees Celsius, the Thailand Meteorological Department said on Sunday.

Cool to cold weather and strong winds are forecast for upper Thailand, including Bangkok. Mountaintops remain cold to very cold. People should watch their health due to the variable weather, the department said.

Meanwhile, the strong northeast monsoon prevails over the Gulf and the South. Isolated heavy rain is forecast in the lower South. People in the South should beware of the severe conditions, the department said. 

Strong winds and waves are likely in the upper Gulf, rising about 2-3 metres in the lower Gulf and above three metres during thundershowers. All ships should proceed with caution and small boats in the Gulf should stay ashore until December 23, the department said. 

A tropical depression covers the middle South China Sea. It is expected to downgrade on December 23-24.

The forecast for the next 24 hours:

Bangkok: Cool with strong winds and a 1-2 degrees Celsius drop in temperature; minimum temperature 21-23°C, maximum 30-33°C; northeasterly winds 10-30 kilometres per hour (kph).

North: Cool to cold with 2-3°C drop in temperature; minimum temperature 14-18°C, maximum 28-31°C; cold to very cold on mountaintops with frost in some places and minimum temperature of 3-14°C; northeasterly winds 10-20kph.

Northeast: Cool to cold with strong winds and 2-3°C drop in temperature; minimum temperature 11-16°C, maximum 25-28°C; cold on the mountaintops with minimum temperature 9-14°C; northeasterly winds 10-30kph.

Surat Thani northward: Northeasterly winds 20-35kph; waves about two metres high and above two metres in thundershowers. Nakhon Si Thammarat southwards: Northeasterly winds 20-40kph; waves 2-3 metres high and above three metres in thundershowers.

Seven-day forecast:

From December 19-23, another strong high pressure cell from China covers upper Thailand and the South China Sea. Cool to cold weather with strong winds and a 2-4°C drop in temperature is likely in the upper country while mountaintops will be cold to very cold. On December 24-25, the high pressure covering upper Thailand will weaken. Temperature will rise by 1-3°C with fog and cool to cold weather in the upper country. A strong northeast monsoon prevails over the Gulf and the South throughout the period, so isolated heavy to very heavy rain is likely. Strong winds and waves are likely over the Gulf of Thailand, about two metres in the upper Gulf and 2-3 metres in the lower Gulf, above three metres in thundershowers. Tropical depression over the middle South China Sea will intensify into a tropical storm. It is expected to downgrade on December 23-24, the department said.

From December 19-23, people in upper Thailand should be careful of their health due to the variable weather, the department said. People in the South should beware of heavy rain. All ships over the Gulf of Thailand should proceed with caution and small boats should stay ashore, the department said.
