The strongest wind near the center of the storm was level 9 (75 - 88 km/h), gusting to level 11. Moving northwest at a speed of 15km/h.

At 7:00 a.m. on September 20, the storm moved westward at a speed of 10-15 km/hour, moving deep inland, gradually weakening into a tropical depression; on the mainland south of Guangdong province, the storm intensity was below level 6.
Due to the influence of the storm, the northern sea area of the North East Sea has strong winds of level 6 - 7, gusts of level 9; the area near the storm's center has strong winds of level 8 - 9, gusts of level 11, waves 3 - 5m high. The sea is very rough.
Vessels operating in the above mentioned dangerous areas are susceptible to the impact of storms, whirlwinds, strong winds and large waves.
Mr. Nguyen Van Huong, Head of Weather Forecast Department, National Center for Hydro-Meteorological Forecasting, said that in addition to the current storm, there is a tropical depression in the Northwest Pacific region that is likely to strengthen into a storm.
Around September 22, the storm is likely to move into the East Sea and directly affect the mainland of Vietnam from September 24 to 26. This is a strong storm, capable of causing strong winds and heavy rain in the Northern region and the Central provinces from Thanh Hoa to Hue.
It is forecasted that from now until the end of 2025, there will be about 5-7 storms and depressions active in the East Sea, of which about 2-4 storms and tropical depressions are likely to directly affect mainland Vietnam.
According to international meteorological agencies, on the evening of September 18 (Vietnam time), the tropical depression numbered 24W intensified into tropical storm Ragasa. The name Ragasa was nominated by the Philippines, meaning “quick”, “speed”, “lightning speed”.
Currently, the Joint Typhoon Warning Center (JTWC - USA) assesses that Ragasa storm is likely to increase in strength very quickly during the weekend (from September 20 to 22). This center believes that the storm may reach super typhoon level when entering the East Sea.
On social networks, some meteorological experts believe that Ragasa will become storm number 9 in the East Sea around September 23. According to the long-term trajectory forecast model provided by the European Center for Medium-Range Weather Forecasts (ECMWF), this storm is likely to pass through the Leizhou Peninsula (China), then directly affect the North Central region and the Northern Delta of Vietnam, especially the Thanh Hoa - Ninh Binh region.
