Boat mooring areas, aquaculture areas, dykes and seawalls in the above-mentioned dangerous areas are all likely to be affected by strong winds, big waves and storm surges and ebbs. Low-lying coastal and estuary areas should be on guard against the risk of flooding due to surges and big waves.
From the night of September 6 to the morning of September 9, in the Northern region and Thanh Hoa, there is a possibility of heavy rain with total rainfall ranging from 100-350mm, in some places over 500mm (the heaviest rain in the Northeast region will be concentrated during the day and night of September 7; in the Northwest region from the evening of September 7 to the night of September 8).
Heavy rains can cause flooding in low-lying areas; flash floods in small rivers and streams, and landslides on steep slopes.
Due to the influence of the wide storm circulation, on September 6, in the Northeast region, the area from Thanh Hoa to Thua Thien Hue needs to be on guard against the risk of thunderstorms, tornadoes, and strong gusts of wind before the storm makes landfall.
