In the next 12 hours, this form will barely move, then slowly move to the northwest at a speed of 5 km/h and weaken into a low pressure area.
Regarding the weakening tropical depression from storm No. 5/Hurricane Conson, on social media this afternoon, an article has been shared regarding the assessment that this low pressure when entering the mainland provinces from Da Nang to Quang Ninh Ngai will have a strong tendency to become a storm again. It is known that this forecast was made after the monitoring results of Ly Son island (Quang Ngai), specifically, the wind strength in this area in the past hours has increased to level 7, level 9.
Regarding this statement, Deputy Director of the National Center for Hydro-Meteorological Forecasting Hoang Phuc Lam, said that the above possibility cannot happen. As Mr. Lam said, the convection clouds near the center of the tropical depression are very weak, so the energy source that can power the tropical depression is limited. Therefore, this form will gradually weaken.
In addition, the sudden change in wind speed or direction over a small area in the center of the tropical depression is very large, so if there is a source of energy, it will not be concentrated near the center but will be scattered. away. Therefore, it is unlikely that this strong tropical depression will turn into a hurricane once it makes landfall.
Talking about the reason that during the past hours, the tropical depression has remained at sea but has not yet reached land, Director of the National Center for Hydro-Meteorological Forecasting Mai Van Khiem said it was because there was no current leading to the pressure. tropical low to shore.
According to this expert, 3 subtropical high pressure systems to the north, east and west are dominating the tropical depression. And the tropical depression in the past few hours has moved less due to the weakening of the high pressure in the north, while the other two high pressures are still operating stably.
The National Center for Hydro-Meteorological Forecasting said that at 4 pm this afternoon, September 12, the center of the tropical depression was located right on the sea from Da Nang to Quang Ngai, with strong winds near the center of level 6-7. , level 9 jerk.
It is forecasted that in the next 12 hours, this pattern will move very little, then slow down at a speed of 5 km/h, in the northwest direction and weaken into a low pressure area. At dawn tomorrow, September 13, the central position of the low pressure area is located on the mainland from Da Nang – Quang Nam, the wind strength near the center drops below level 6.
The meteorological agency warned tonight (September 12), due to the circulation of tropical depression, the area from Da Nang to the north of Quang Ngai will continue to rain heavily. Rainfall is over 150 mm in some places.
The area from Quang Tri to Thua Thien Hue, due to the influence of the circulation of heavy rain storms, will appear continuously until the end of September 13 with an amount of over 200 mm in some places.
From this afternoon of September 12 to September 14, due to the influence of storm circulation, the heavy rain area will expand to provinces from Quang Binh to Thanh Hoa, some places with more than 150 mm of rain.
