According to Tran Quang Nang, the head of the Weather Forecasting Office under the National Centre for Hydro-Meteorological Forecasting, from the night of October 12, the Northern Mountains will feel the impact of the northeast monsoon, which could bring scattered thunderstorms to the area.
On October 13, the cold air will intensify, affecting the northern midland and delta areas, as well as reaching the northern parts of the Central region over the following days.
“It is a fairly strong monsoon so it can cause the temperature drop by around 6-10C in the mountains and by 3-6C in the plains,” said Nang, adding that the lowest temperature during this monsoon spell in the Northern Delta region (including Hanoi) is likely to decrease to 19-22C, while 15-18C could be recorded in the Northern Mountains region, even 12C in some places in the high mountainous areas such as Mau Son, Sa Pa, and Tam Dao.
Scattered thunderstorms are forecast in the northern region, while provinces and cities in the Central region between the provinces of Thanh Hoa to Quang Nam could suffer from heavy rains from October 13-16.
Not only will it cause heavy rainfall and reduced temperatures on the mainland, the monsoon will also bring strong winds to the waters of the Tonkin Gulf and the northern part of the East Sea from Sunday night and will last until 2-3 days later.
