Storm No. 13 will be strong when it reaches shore
Sir, when is the forecast for storm No. 13 to make landfall and landfall in which areas?
- At 5:00 a.m. on November 5, storm Kalmaegi entered the eastern sea of the central East Sea, becoming storm No. 13, level 13 intensity, gusting to level 16.
It is forecasted that around the afternoon of November 6, the storm will enter the sea area of Da Nang - Khanh Hoa city. Around the night of November 6 (after 9:00 p.m. on November 6) to early morning of November 7, the storm will make landfall in the provinces from Quang Ngai to Dak Lak, then move to Laos, weaken into a tropical depression and gradually dissipate.
Due to the influence of a wide storm circulation, it is necessary to be on guard against the risk of thunderstorms, tornadoes and strong gusts of wind both before and during the storm's landfall.
What are the notable characteristics of this storm, is the storm likely to strengthen or not, sir?
- The storm is very strong, moving quickly, with a wide storm circulation, operating on the tropical convergence zone, high sea surface temperatures, humid atmosphere, and weak cold air. Therefore, it is likely that the storm will strengthen after entering the East Sea.
International and Vietnamese forecasts are relatively consistent in trajectory and intensity.
