The location of the storm's formation is in the northern area of the East Sea, however, the point of storm formation is quite high, in the northern area of the North East Sea and the direction of movement is much higher than the north. The time when typhoons typically hit the North and have begun to shift south and affect the Central region, but this typhoon makes landfall in China.
"Although it will make landfall in China, after making landfall, storm No. 7 will quickly weaken into a low pressure area, then drift westward, towards our country. It is likely that from the afternoon and night of September 9 to 11, the post-storm No. 7 circulation will cause a large-scale heavy rain in the North, focusing on the midlands and mountainous areas of the Northeast" - Mr. Khiem commented.
