The National Centre for Hydro-Meteorological Forecasting on January 25 warned that the temperature is predicted to fall to 10-14 degrees Celsius in the northern delta provinces and 7-10 degree Celsius in northern mountainous areas from January 29.
The northern region is also forecast to see showers, thunderstorms, hail and strong winds between January 28 and February 3, the centre said.
However, the weather will become warmer from February 3 in the region, with temperatures of 13-20 degrees Celsius in the delta provinces and 10-13 degrees Celsius in mountainous provinces, the centre said.
Temperatures in provinces from Thanh Hoa to Thua Thien-Hue are expected to be 13-23 degrees Celsius between January 29 and February 2.
The provinces are also forecast to see showers during this time, the centre said.
The temperatures in localities from Da Nang to Binh Thuan provinces are predicted to be 19-30 degrees Celsius between January 30 and February 3. Sunny weather is forecast in these localities.
The southern region will experience sunny days from February 1-6 with temperatures of 21-33 degrees Celsius, the centre added.
The centre also warned that a tropical low-pressure system south of the Philippines will enter the southern part of the East Sea and is likely to gain strength on February 2 or 3.
In response to the situation, the National Steering Committee for Natural Disaster Prevention and Control has ordered all relevant provinces and cities to closely monitor the weather’s developments to guide local people and prevent damage from severe cold weather, frost, heavy rain and thunderstorms during the Tet holiday.
The provinces and cities are told to make plans to respond to the situation, especially preparing equipment and materials as well as rescue forces that stand ready to help local people overcome the consequences quickly and effectively, the committee said.
They are ordered to implement measures to ensure safety for people, plants and animals in mountainous areas during the severe cold weather and install warning signs on roads that are likely to be icy and slippery to ensure safety for road users.
Localities are assigned to work with relevant agencies and local media outlets to provide local people with information so they can cope with the cold weather, such as reinforcing their roofs and protecting household items, vegetables, crops, and livestock in accordance with specific local conditions to minimise damage.
Coastal localities from Quang Ninh to Kien Giang have to inform offshore vessels about the weather developments so that they could have appropriate plans to cope with incidents, the committee said.
