Rising water due to coastal storms:
The coastal areas of Quang Ninh-Hai Phong provinces will have storm surge of 0.5-1.0m high. High risk of landslides, sea embankments, destruction of aquaculture areas, ships and boats anchored along the coast due to strong winds, rising sea levels and big waves.
On land:
From early morning on September 25, coastal areas from Quang Ninh to Thanh Hoa will have winds gradually increasing to level 6-7, then increasing to level 8, near the storm center level 9-10, gusting to level 12; deep inland areas in the Northeast will have strong winds of level 6-7, gusting to level 8-9.
From the night of September 24 to September 26, in the Northern region, Thanh Hoa and Nghe An, there will be heavy to very heavy rain with common rainfall of 100-250mm, locally over 400mm. Beware of heavy rain causing urban flooding.
Heavy rain is likely to cause flooding in low-lying areas; flash floods on small rivers and streams, landslides on steep slopes.
Due to the influence of a wide storm circulation, it is necessary to be on guard against the risk of thunderstorms, tornadoes and strong gusts of wind both before and during the storm's landfall.
