A cold air mass is about to sweep down to our country, causing temperatures in the North to remain low, with severe cold and frost continuing, while the Central region is expecting heavy rainfall.
The National Center for Meteorological and Hydrological Forecasting has reported that a cold air mass is moving southward.
The North is about to welcome reinforced cold air.
It is forecasted that around the night of December 20, this cold air mass will affect the northern region, and later impact the North Central and Central regions. Northeastern winds on land will gradually strengthen to level 3, while coastal areas may experience level 4-5 winds, with gusts reaching level 6-7.
Due to the influence of the cold air, from December 21 to 23, the North and the provinces from Thanh Hoa to Thua Thien Hue will experience cold weather, with some mountainous areas in the North facing severe cold and frost; there may be instances of ice and hoarfrost in the northern mountainous regions.
During this cold spell, the lowest temperatures in the North and North Central regions are expected to range from 10-13 degrees Celsius, in the northern mountainous areas from 6-9 degrees Celsius, with some high mountainous areas dropping below 6 degrees Celsius. The region from Quang Binh to Thua Thien Hue is expected to see temperatures between 13-16 degrees Celsius.
Forecast for today, December 20: The North will continue to experience piercing cold weather at night, sunny weather during the day, and light fog in the early morning. The lowest temperatures in the lowland areas will range from 8-11 degrees Celsius, while in the mountainous regions, temperatures will be between 4-7 degrees Celsius, and in high mountainous areas, below 2 degrees Celsius. The highest daytime temperatures will range from 20-22 degrees Celsius.

The weather will remain extremely cold, with the lowest temperatures between 8-11 degrees Celsius and the highest temperatures from 20-22 degrees Celsius.
Forecast from now until the end of December: The North and North Central regions will continuously be affected by supplementary cold air, leading to prolonged cold weather.

The area from Quang Tri to Quang Ngai will have moderate rain, with some places experiencing heavy to very heavy rain. Thunderstorms may bring risks of lightning and strong gusty winds.
