By 7 p.m. on the same day, the storm is expected to further weaken into a low-pressure system.
According to the National Center for Hydro-Meteorological and Hydrological Forecasting, at 7 a.m. on October 9, the storm's center was located at approximately 21.6 degrees North Latitude and 113.2 degrees East Longitude over the waters to the South of Guangdong Province in China. The strongest winds near the storm's center reached level 9 (75-88 km/h), gusting to level 12, and the storm was moving slowly in a westerly direction at a speed of about 5 km/h.
The forecast indicates that by 7 a.m. on October 10, the storm will track Southwestward at a speed of 10-15 km/h and diminish into a tropical depression, accompanied by strong winds at levels 6-7, occasionally gusting to level 9. By 7 p.m. on the same day, the storm is expected to further weaken into a low-pressure system.
Over the next 24 hours, the Northwestern waters of the North of the East Sea will encounter strong winds at levels 6-7. In the vicinity of the storm's center, very strong winds at levels 8-9, with gusts reaching level 12, will prevail, leading to very rough seas.
Additionally, as a result of the reinforced cold air mass, starting from the early hours of October 10, the waters in the Gulf of Tonkin will encounter strong northeasterly winds at level 6, gusting to level 8, leading to rough sea conditions.
Wave heights in the North of the East Sea are between 2-3 meters, while in the vicinity of the storm's center, wave heights reach 3-5 meters. Starting from the morning of October 10, the Gulf of Tonkin will experience wave heights between 2-3 meters.
