According to the National Center for Hydro-Meteorological Forecasting, at 4:00 p.m. on October 21, the center of the storm was located at about 17.5 degrees North latitude; 111.9 degrees East longitude, in the sea north of Hoang Sa special zone, about 420 km East Northeast of Da Nang city. The strongest wind near the center of the storm was level 9 - 10 (75-102 km/h), gusting to level 12. Moving in the West Southwest direction, speed 10 - 15 km/h.

Forecast by 4:00 p.m. on October 22, the storm is about 125 km east-northeast of Da Nang city, with strong winds of level 8, gusts of level 10, moving in the West-Southwest direction at a speed of about 10 - 15 km/h and gradually weakening. The affected area is the sea area west of the North East Sea (including Hoang Sa special zone), the sea area from South Quang Tri to Quang Ngai (including Con Co special zones, Ly Son and Cu Lao Cham island), disaster risk level 3.

Then, at 4:00 p.m. on October 23, the storm in the Southern Laos area, with winds below level 6, moved in the West Southwest direction at a speed of about 10 - 15 km/h and was likely to gradually weaken into a tropical depression and then a low pressure area. The affected area is the sea area from Southern Quang Tri to Quang Ngai (including the special zones of Con Co, Ly Son and Cu Lao Cham island), the mainland coastal provinces and cities from Quang Tri to Da Nang.

Due to the impact of the storm, the western sea area of the North East Sea (including Hoang Sa special zone) has strong winds of level 7 - 8; the area near the storm's eye has strong winds of level 9 - 10, gusting to level 12; waves are 3 - 5m high, the area near the storm's eye is 5 - 7m high, the sea is very rough.

The sea area from Quang Tri to Quang Ngai (including Con Co special zone, Cu Lao Cham island and Ly Son special zone) has strong winds of level 6, increasing to level 7 from the morning of October 22, the area near the storm center has level 8, gusts of level 10, waves 3-5 high, rough seas.

Coastal areas of provinces and cities from Quang Tri to Da Nang have storm surges of 0.3 - 0.5m high.

All ships and boats operating in the above-mentioned dangerous areas are likely to be affected by storms, whirlwinds, strong winds, and large waves. Coastal areas from Quang Tri to Da Nang need to be on guard against large waves combined with high tides and rising water due to strong winds, flooding in low-lying areas, and coastal erosion.

On land, due to the influence of the circulation of typhoon No. 12 combined with a strong surge of cold air, from the afternoon of October 22nd, strong winds gradually increased to level 6, sometimes level 7, with gusts of level 8-9, along the coastal areas of provinces from Quang Tri to Da Nang.

Along with that, also due to the influence of storm circulation and cold air combined with East wind disturbances and terrain effects, from noon on October 22 to October 27, the area from Ha Tinh to Quang Ngai is likely to have widespread heavy rain (heavy rain concentrated from the afternoon of October 22 to the end of October 23).

The total rainfall in Ha Tinh to northern Quang Tri and Quang Ngai is generally around 200-400mm, with some areas exceeding 500mm. In the area from southern Quang Tri to Da Nang city, rainfall is generally 500-700mm, with some areas exceeding 900mm. A warning is issued for heavy rainfall exceeding 200mm/3 hours.

Heavy rains in the Central region are likely to last until the end of October 2025. There is a high risk of flash floods and landslides in mountainous areas, and flooding in low-lying and urban areas.

Associate Professor, Doctor, Director of the National Center for Hydro-Meteorological Forecasting Mai Van Khiem noted: "Localities need to pay attention to safely operating hydroelectric and irrigation reservoirs before, during and after the storm, and prepare response plans for flood scenarios on rivers from Quang Tri to Quang Ngai that may reach alert level 3 and exceed alert level 3. Beware of the risk of thunderstorms, tornadoes with strong gusts of wind in the storm circulation area, both before and during the storm's landfall. Forecast level 3 natural disaster risk due to floods and inundations".
