Cold air moving down to the North will cause temperatures in mountainous areas to drop to freezing levels, while in the plains the lowest temperature will be 18-20 degrees Celsius.
The National Center for Hydro-Meteorological Forecasting said that around the afternoon and night of November 17, cold air will affect the Northeast region and then expand to the plains and Northwest.
The American website Accuweather predicts that tomorrow Hanoi will drop about 3 degrees compared to today, down to 21-30 degrees Celsius, and by mid-week the daily temperature will fluctuate between 19-28 degrees. High points over 1,500 meters above sea level such as Sa Pa (Lao Cai) will have 14-22 degrees at the beginning of the week, and by the end of the week it will drop to the freezing threshold (average daily temperature below 13 degrees) from 9-15 degrees Celsius.
The North Central provinces will also be affected by this cold air mass with common temperatures of 18-20 degrees, and in mountainous areas below 15 degrees.
In addition, the cold air will also cause strong northeast winds of level 3 on land and level 4 in coastal areas. At sea, from tomorrow, strong winds of level 6, gusts of level 7-8, waves 2-4 m high. In the North East Sea, strong winds of level 6-7, gusts of level 8-9, waves 3-5 m high.
Mr. Nguyen Van Huong, Head of Weather Forecasting Department, National Center for Hydro-Meteorological Forecasting, said the reason why the temperature in the North remains high after the beginning of winter is due to the weakening of cold air mass and the appearance of divergent wind fields, creating conditions for prolonged heat.
It is forecasted that in the main winter months, from December 2024 to February 2025, the average temperature across the country will generally be approximately the same as the average for the same period in many years. In December 2024, the Northwest, Central and South Central regions will be 0.5-1 degrees Celsius higher.
Cold air causing widespread severe cold in the North is likely to appear from the second half of December and be active until February 2025. The meteorological agency recommends that people should be on guard against the possibility of prolonged severe cold spells, especially in the northern mountainous areas, accompanied by frost and ice.
