HÀ NỘI The northeastern region of Việt Nam will experience heavy rainfall, with some regions receiving exceptionally heavy precipitation, from Saturday through Monday morning, warned the National Center for Hydro-Meteorological Forecasting.

Lào Cai, Yên Bái, and Sơn La are particularly at risk, with anticipated rainfall totals ranging from 150 to 300mm. In isolated areas, rainfall could exceed 400mm.

Currently, Bạch Long Vỹ Island has recorded strong winds reaching level 12, gusting to level 14. On Cô Tô Island, winds have reached level 7 with gusts of level 11, and they are expected to intensify in the coming hours. Wind speeds in these island districts are forecasted to reach levels 12-13, with gusts up to levels 14-15, posing significant danger to structures, especially civil buildings. Large waves may cause coastal erosion, damage seawalls, and impact docking areas for fishing vessels if they are not properly secured.

Marine conditions are expected to be hazardous, with large storm-induced waves posing a significant threat to coastal tourism zones, docking areas, and aquaculture farms, particularly in Quảng Ninh and Thái Bình. Coastal erosion is also a concern as the storm approaches.

Even though low tides are predicted to coincide with the storm's landfall, the combination of storm surges and large waves could still result in flooding in many low-lying coastal areas.

Strong winds of levels 10-12, with gusts up to level 14, are also a significant concern for Quảng Ninh, Hải Phòng, and Thái Bình. The winds can cause severe damage to construction projects, rip off weak roofs, and dislodge large advertising boards.

Heavy rain in the northern region is forecast to total between 150-350mm, with extreme rainfall of up to 500mm in certain areas. The heavy rain, concentrated over a short period on September 7 and 8, will likely lead to widespread flooding as water cannot drain quickly enough, particularly in urban areas, densely populated zones, open-pit coal mines, and underground mining operations in Quảng Ninh.

The National Centre for Hydro-Meteorological Forecasting has also issued warnings of a high risk of flash floods and landslides in the mountainous regions of the North, and in Thanh Hóa and Nghệ An provinces.

Smaller rivers and upper streams in northern mountainous provinces, particularly in Quảng Ninh, Lạng Sơn, Cao Bằng, Tuyên Quang, and Hòa Bình, may reach alert levels 2-3.

There is a warning of widespread flooding in the mountainous, midland, and delta regions of the North, particularly in Quảng Ninh, Hải Phòng, Lạng Sơn, Cao Bằng, Hà Giang, Yên Bái, Bắc Kạn, and Thái Nguyên.

From the night of September 6 to 8, special attention should be paid to the following high-risk districts: Đông Triều Town, Quảng Yên, Móng Cái City, Cẩm Phả, Uông Bí, Hạ Long, Ba Chẽ, Vân Đồn, Tiên Yên, Hải Hà, Đầm Hà, Bình Liêu in Quảng Ninh; and Hữu Lũng, Bình Gia, Lộc Bình, Văn Lãng, Cao Lộc, Văn Quan, Chi Lăng, Bắc Sơn, Đình Lập, Lạng Sơn City in Lạng Sơn.
