Typhoon 5 is considered to be the strongest storm since the start of the storm season in 2020 with a strong impact level of level 12 14. The storm will directly affect Ha Tinh to Quang Ngai.
Lao Dong newspaper reporter had an interview with Mr. Nguyen Van Huong – Head of the Weather Forecast Department, National Hydrometeorological Forecast Center forecasting the direction of the movement, the intensity of storm No. 5 when landing in the instant land.
Sir, are you currently forecasting typhoon n. 5 how?
– At 10 o’clock on September 17, the location of the center of Storm No. 5 was approximately 14.6 north latitude; 113.5 degrees east longitude, about 340 km from the Hoang Sa archipelago to the southeast. The strongest wind near the center of a heavy storm level 10, impact level 12.
The typhoon was most powerful when it was 100 kilometers from the coast. At this time the storm can be strong at level 12, reaching levels 14-15. Currently, the storm is affected by cold air descending from the north.
The interaction of cold air and storms will cause storms to have a very complex road behavior. We estimate that the storm will have a direct impact from Ha Tinh to Quang Ngai and the focus area of the storm is from Quang Binh to Quang Ngai.
However, it is not ruled out that the storm descends and affects the south. With such storm developments, the range of rain and strong winds will be very wide across most of the South China Sea.
At magnitude 12 and intensity level 14, is Hurricane 5 the strongest storm since early 2020, sir?
– That is absolutely correct! The first 4 storms of the season are not too strong and this storm that we forecast can reach level 12. Due to such a strong intensity, in the hydrometeorological forecasts, we give the scene. Report the risk level as level 4. That represents the strongest storm level since the start of the 2020 storm season until now.
The intensity of the storm is strongest when it is 100 km from the mainland, but the intensity when the storm arrives is still relatively strong, around 10-11 in the coastal zone and the deep interior is level 8 level 9.
So what objective conditions are responsible for Hurricane No. 5 moving so fast and intensely, sir?
– This storm has a characteristic when it comes to the East Sea, the sea surface temperature is quite high, around 29-31 degrees. These are very favorable conditions for the formation of storms. Meanwhile, at the height of 3000-5000m, the structure has the east wind invading, causing strong storm activity. Also, the southwest monsoon is active during this period. The interaction between these forms is the condition for the storm to move fast and hard.
In addition to concerns about high winds and rising sea levels, rain after storms is always a dangerous form. So what about this storm, will it cause prolonged rain or not sir?
– We estimate that the rainfall in this phase in the Central region ranges between 200-300 mm / wave, in some places more than 400 mm / hour. However, there was no winter wind, so the rain after the storm quickly ended. Rainfall before and during the storm is affected, that is, from September 17 to 18, less rain after the storm. Since the morning of September 19, the rain has decreased rapidly in central Vietnam.
Thank you sincerely!
