New tropical depression likely to strengthen into storm in the East Sea
This afternoon, September 23, the Department of Hydrometeorology (Ministry of Agriculture and Environment) said that a tropical depression has just appeared in the eastern part of the Philippines. It is forecasted that September 24 will likely strengthen into a storm, September 27 is likely to move into the East Sea to become storm No. 10.
Currently, forecasts for the development of storm No. 10 are still very dispersed. European and Japanese forecasts predict that Typhoon No. 10 will move north, towards the north of China or the southern part of China. However, the US forecast predicts that the storm will move into the Central region (focusing on the provinces from Ha Tinh - Quang Ngai).
The assessment of the Vietnam Meteorological Agency believes that the possibility of the storm moving into the Central region is the most likely scenario because at this stage, according to the climate law, the storm will move into the Central region. The possibility of this storm strengthening to super typhoon or a storm stronger than level 13 is not high. The Department of Hydrometeorology continued to monitor and around September 25, issued a storm warning near the East Sea.
