This year's typhoon has formed three successive attacks, which has a great impact on China's coastal areas. The 16th typhoon of this year, Marva, was upgraded to the level of strong tropical storm yesterday afternoon. But this time the route map of typhoon Marva is a little weird!
At 7:00 this morning, its center is located in the northeast of the South China Sea, about 135 kilometers east by south of Huilai, Guangdong Province, and will land in Guangdong from this afternoon to evening. It is expected that Guangdong and Fujian coastal areas will encounter strong storm and rain. In addition, there will be strong rainfall in Huanghuai, Jianghuai and other places.
It is predicted that 'Marwa' will move to the northwest at a speed of 5-10km per hour, and will land in the coastal area from Shanwei to Shantou in Guangdong Province (tropical storm or strong tropical storm, 8-10, 20-25m / s) from this afternoon to the evening. After landing, the intensity will decrease rapidly.
When will Marva land?
According to the information released by the Central Meteorological Station in the morning, 'Marva' is expected to land in the coastal area from Shanwei to Shantou this evening (tropical storm or strong tropical storm, 20-25m / s, 8-10). (editor's note: due to the strange position of 'Marwa', the news was released at 4:00 p.m. of 'Guangdong weather'. It is expected that 'Marwa' will land in the coastal area from Shanwei to Huilai this evening. )
'Marva' is weird, pay attention to defense!!
This afternoon, the official microblog of "Guangdong weather" said that we must not take lightly the defense of Typhoon "Marwa". Compared with the first two typhoons, Marwa's temperament is very strange, as follows:
Marva belongs to the South China Sea typhoon in the meteorological industry, famous for its complexity and changefulness, and she is walking in the legendary snake like pace!
Marwa is very asymmetric. Don't just look at the typhoon center. At present, the strong convective weather + heavy rainfall are mainly concentrated in the southwest of the typhoon center, not the landing point.
Previously, Marva was very slow, but she began to speed up.
The typhoon is very close. We should be alert to the impact of landing as soon as it strides. Therefore, we must take measures to prevent it.
How to do the defense? At what pace? Refer to the defense guidelines corresponding to the local meteorological warning signal level
Defense 'Marva', pay attention to these aspects!
In recent years, typhoons affect our city more frequently. Shortly after the "Pigeon" Paka, typhoon "Marwa" will bring heavy rain to Dongguan.
The city's third prevention Office reminded the general public to pay attention to safety in typhoon days. In case of extreme weather such as strong storm and rain, they should try to stay indoors and avoid going out.
The frequent and high intensity typhoons in the near future have caused severe rainstorms, storm surges and other natural disasters, which have brought severe challenges and tests to the city's defense work.
2. The storm surge brought by the "Pigeon" Paka "has intensified the damage to the water conservancy engineering facilities in the city, such as the river levees and sea dikes. Some damaged facilities have yet to be fully repaired in the future, and they are also vulnerable to the attack of new storms, which is prone to produce superimposed disasters.
3. Large outdoor billboards, tower cranes, scaffolds and other high-altitude equipment on construction sites have been attacked by strong wind for many times, which may have been damaged imperceptibly and may have potential safety hazards of collapse.
The 4-stage concentrated rainstorm is easy to cause loose soil and water, high river water level, and the risk of flood, mountain flood, debris flow and landslide geological disaster in mountainous area, hilly area and Shima River Basin is greatly increased.
