According to the new weather forecast from the National Center for Hydro-Meteorological Forecasting, on the night of October 20, the center of the storm was at about 18.5° North latitude - 114.0° East longitude, about 270 km northeast of the Hoang Sa archipelago.
The strongest wind near the storm center is level 9-10 (75-102 km/h), gusting to level 12. The storm is moving west-northwest at a speed of about 20 km/h.
It is forecasted that by the evening of October 21, the storm will move westward, then turn west-southwest at a speed of 10-15 km/h, in the area north of the Hoang Sa archipelago. The wind intensity increased to level 10-11, gusting to level 13.
The natural disaster risk level is determined at level 3 for the northern East Sea (including the Hoang Sa archipelago) and the southern sea of Quang Tri - Quang Ngai (including Ly Son island).
The northern East Sea area (including Hoang Sa archipelago) has strong winds of level 7-8, near the storm center strong winds of level 9-11, gusting to level 13. Waves are 3.0-5.0 m high, near the center of the storm there are waves 5.0-7.0 m high, the sea is very rough.
The sea area from southern Quang Tri to Quang Ngai (including Ly Son Island) will have strong winds of level 6, from the morning of October 22 increasing to level 7; the area near the storm center will have strong winds of level 8-9, gusting to level 11. Waves are 3.0-5.0 m high, the sea is very rough.
All ships and boats in the danger zone need to pay special attention because they are likely to be affected by thunderstorms, tornadoes, strong winds and large waves.
Due to the influence of the storm's circulation combined with cold air and winter wind disturbances, from the night of October 22 to October 26, the area from Ha Tinh to Quang Ngai will have widespread heavy rain.
Ha Tinh - northern Quang Tri and Quang Ngai areas will have common rainfall from 200-400 mm, some places over 500 mm.
The southern Quang Tri - Da Nang area will have very heavy rainfall, generally 500-700 mm, locally over 900 mm.
Heavy rain is likely to last until the end of October 2025, causing a high risk of flash floods, landslides in mountainous areas and flooding in low-lying areas and urban areas.
Localities need to proactively ensure the safety of reservoirs, and at the same time prepare flood response plans on rivers from Quang Tri to Quang Ngai that are likely to reach and exceed alert level 3. The risk level of natural disasters due to floods and inundation is assessed at level 3.
