How strong is Doksuri?

Typhoon Doksuri is forecasted to be strongest from 2014 up to now, 11-12 wind level, heavy rain from North to Central Central and a part of Central Highlands.

According to the latest news at 11:00 noon on September 14, in just three hours this morning, Typhoon Doksuri (storm No. 10) was up to one level, into level 11 with maximum wind power (100 to 115 km / h). Around noon to late afternoon (September 15), the storm will enter the provinces from Nghe An to Quang Tri, causing strong winds of level 11-12, level 15 jerks, then weakening.

Meteorological agency rated Doksuri as a strong storm, disaster risk level 4, the highest since 2014 up to now. This level is given with strong typhoon level 10-11 operating on land in Southern Vietnam; 12-15 typhoons operate in coastal waters, North and Central mainland and super typhoons from level 16 or higher in the East Sea (including the Paracel and Spratly Islands).

Mr. Le Thanh Hai, Deputy Director of the National Center for Meteorological and Hydrology, said that according to this level, in 2013, Vietnam had two storms reaching the level of disaster risk 4 (Typhoon Wutip and Nari) and one Level 5. The time of Haiyan storm going through the Philippines and approaching the Vietnamese mainland (November 2013), the storm reached level 5.

Compared to super typhoon Harvey, Irma in the US, Hai said that these two storms reached Cat 4-5 (maximum winds of 209km / h or more) according to the American forecast, while Doksuri reached Cat. 3.

"So Doksuri is a very strong storm, the wind level is 12-13, level 15 is jerky, and the ability to reach as Harvey or Irma is not available," Hai said.

Four points of interest in Typhoon Doksuri

First , strong wind level level 11-12, level 15 jerky, extremely destructive power, many buildings fail.
Secondly , the storm lies in the range of tropical convergence so the size is very large. Range of strong wind level 6 from Quang Ninh to Quang Ngai; Grade 10 wind from Thanh Hoa to Thua Thien Hue and level 10-11 Ha Tinh - Quang Binh.

The storm will cause widespread rain, stretching from the southern part of the Northern Delta, a part of the North West to all the provinces of Thanh Hoa - Thua Thien Hue and spread to both Central Central and Northern Central Highlands.

Third , ocean waves in the center of the storm can be 10m high, coastal areas 5-6m. Typhoons hit at the right time of the tide, so the coast from Hai Phong to Quang Binh can rise 1m high, along the coast of Thanh Hoa to Ha Tinh about 2m.
Finally , meteorological and sea forecasters are concerned about the phenomenon of sprinting in storms . In the coastal area from Nghe An to Quang Tri, when there are strong storms near the mainland, the wind zone from the mainland to the center of the storm can push coastal water out to the sea, creating a phenomenon of sprinting.

After that, when the typhoon landed, the water surged again, so the level of destruction would be very large.

Formed from a tropical depression in the east of the Philippines, Doksuri stormed this archipelago on 13 September, becoming the 10th storm in the South China Sea, strong at level 8 (maximum 75km / h).

Previously 9 storms were mostly formed right on the East Sea, weak intensity; or originating from the eastern Philippines and heading to China.

Wind storm levels:

Level 10 storm causes strong winds of 89-102km / h, spilling trees, houses and electric poles. The sea was fierce, sinking ships.
Level 11 storm causes strong winds of 103-117km / h, heavy rain, causing flooding, landslides with flash floods and flooding in highland and low-lying areas.
Level 12 hurricane causes 118-133km / h, creating the risk of an unstable dyke.
