Experts from the National Center for Meteorology and Hydrology (Centro Nacional de Hidrometeorología) assessed Typhoon No. 9 (international name Molave) as the strongest storm since early 2020 until now.
The north central coast was also affected by the storm
Typhoon No. 9 has three characteristics: fast movement, strong intensity, wide range of influence in the East Sea. Due to the rapidly moving storms, it is possible to directly affect the marine waters as of October 27 in the afternoon. On the night of October 27, the storms have the ability to directly affect the central and south central continent.

Mr. Nguyen Ba Thuy, Deputy Director of the National Hydrometeorology Center, said that from the beginning of 2020 until now, Typhoon No. 9 is considered the strongest storm, entering the East Sea with a magnitude of 12-13, it predicts that the waves will be more than 10 m high.
“This is a rare case in the East Sea, where a storm occurs with such high waves,” Thuy said.
When the storm enters the Central Sea, this is an open and deep sea, so the possibility of attenuation of the waves is negligible. Therefore, the sea area from Da Nang to Binh Dinh is likely to have waves 6 to 7 m high.
Thuy recalled: “In the experience of Typhoon Damrey in 2017 when it landed in Phu Yen – Khanh Hoa, Binh Dinh province was hundreds of kilometers away, but six large transport ships in Quy Nhon port also sank. 13 people missing. “
With the analysis above, meteorological experts are concerned that when the storm hits, not only the storm’s focus area but also the central north shore will be affected.
Typhoon number 9 is at “hurricane” level, concerned about rising sea levels
As for the rise in water, meteorological experts also noted that two storms were recorded in this area. Typhoon Xangsane touched down in Vietnam in September 2006 and Typhoon Ketsana made landfall in September 2009, causing the water at the Son Tra (Da Nang) hydrological station to rise to 1.5 m, just at the time of tide high. extensive flooding, especially in the lagoon area in the Hoi An Sea.

“With this storm No. 9, we are also concerned about the possibility of rising sea levels, especially in the case of storms that fall at night, at high tide. This is an issue that we will recommend to prevention agencies. natural disasters “- said Mr. Thuy.
Regarding issues of specific impacts on the sea and coastal areas, especially maritime routes, seaports such as the port of Quy Nhon – Binh Dinh, meteorological experts are concerned that even in the protected area, it is due to the spread and wave resonance in seaports also present a very high risk of waves.
In 2017, when Typhoon Damrey hit Khanh Hoa, it caused great damage to aquaculture areas.
In addition, experts are also concerned about the destruction of embankments, coastal works and estuaries. Normally, strong northeast monsoons often destroy embankments and estuaries in the central region, but this storm alone can cause several times more impacts than a northeast monsoon.
“My last concern is that it has been a long time since there was a strong storm that can cause flooding in the area from Thua Thien – Hue to Da Nang, where there is no marine levee system, Some areas are relatively low,” shared the Mr. Thuy.
The night of October 27 began to have heavy rains with thunderstorms
Mr. Hoang Phuc Lam, Deputy Director of the National Center for Hydrometeorology, also said that the wind level from 12 to 15 is the wind level called hurricane. With hurricane number 9, the current wind level is 12-13, so it can also be called a hurricane. From level 16 it becomes a super storm.

Further information, Mr. Lam said that Storm No. 9 was completely different from Storm No. 8 above. Because storm number 9 was combined with cold air, heavy post-storm rains were concentrated in the north and central center. From October 28 to October 31, rainfall can reach 500 mm and although this area is far from the storm, the impact of the rain after the storm is greater.
“Most of the storms in the south will bring very strong convection clouds. According to the forecast on the 28th, new storms will arrive near the coast, but as of October 27 there have been heavy rains with thunderstorms and gusts of wind, so migration works are expected. The resistance of the house must be completed before October 27 “- emphasized Mr. Lam.
According to the Central Steering Committee for the Prevention and Control of Natural Disasters, Storm No. 9 was as strong as Storm Damrey in 2017, causing serious damage to people, property and infrastructure, with more than 100 deaths and tens of billions of dong …
(OLP) – Before tonight, October 27, about 600,000 people in the provinces from Thua Thien Hue to Phu Yen are expected to be evacuated to avoid damage from Typhoon 9.
