Regarding the special factors of storm No. 5 Kajiki, the reporter discussed with Mr. Hoang Phuc Lam - Deputy Director of the National Center for Hydro-Meteorological Forecasting to clarify.
Sir, storm No. 5 is expected to move rapidly, increasing to level 7 in just 2 days and forecasting dangerous impacts. So what is the cause of the impact on the trajectory and intensity of this storm that has caused it to continuously intensify like this?
- Environmental factors that can affect the trajectory and intensity of storm No. 5 can be mentioned as from the time of entering the East Sea, the environment for the storm to form and develop is quite favorable. The sea surface temperature along the path of storm No. 5 is approximately and above 30 degrees Celsius.
Secondly, the current specific approach is the subtropical high pressure encroaching quite deeply to the west. Therefore, the storm moves relatively steadily and at a fast pace.
Another favorable factor that makes the intensity of storms continuously maintain and even increase is that the storm has little interaction with the islands. Like other storms, it could pass through Hainan Island (China), for example, which could weaken the storm slightly. But this storm No. 5 is all about the trajectory of moving at sea, so there is no process for the storm to weaken.
Therefore, we believe that the current high risk is that the storm intensity could increase to level 14. And there are also some scenarios that show that the storm could reach Category 15. However, the scenario of reaching level 15 is not as high as the forecast for level 14.
The storm is forecast to make landfall in Thanh Hoa to Quang Tri and this will be the area most affected. More specifically, which provinces are forecast to be the focus of heavy rain and strong winds, sir?
- Due to the wide circulation of storm No. 5, the rain will extend from Thanh Hoa to the north of Quang Tri, the old Quang Binh. The focus will be on the three provinces of Nghe An, Ha Tinh and the north of Quang Tri, the old Quang Binh.
These are three provinces that focus on both rain and wind, waves and rising water.
As for flash floods and landslides, they will move slightly north, that is, the mountainous areas of Thanh Hoa, Nghe An and Ha Tinh.
So when will storm No. 5 start affecting and when will it be the peak, Mr. and Mr. have any recommendations for the people?
- The rain has started but it is not the time of the heaviest rain. From tonight, August 24, the wind will start to get stronger. Tomorrow morning, August 25, the forecast is to start with winds of level 9 - 10, making it very difficult for people in the affected area to move.
Therefore, all response activities of localities on building houses, reinforcing works, harvesting crops or evacuation will have to end before 10:00 p.m. today, August 24.
The peak of heavy rain and strong winds from Thanh Hoa to the north of Quang Tri will be concentrated tomorrow, August 25. This storm is characterized by fast travel, so the impact of strong winds and heavy rain will pass quickly, and may only last for about 24 hours.
It is worth noting that the rain and wind after the storm will extend to the mountainous areas of Thanh Hoa, Nghe An, Ha Tinh and to both the Central and Upper Laos, the Northern Delta region.
Sincerely thank you!
