Impact of Typhoon Sura on Shenzhen
In 223, the ninth typhoon Sura had a serious wind and rain impact on Shenzhen.
Sura moved to the north-north direction at a speed of 1-15 kilometers per hour on September 1st, with little change in intensity. It is expected that Sura will attack Shenzhen directly from tonight to tomorrow morning, or move close within 1 kilometers of Shenzhen.
under the influence of Sura, strong winds and heavy rains occurred in Shenzhen. The maximum wind force near the center of Typhoon Sura reached 16 (55 m/s), and the lowest pressure in the center was 93 hectopascals. This strong wind has caused great damage to the traffic, buildings and trees in Shenzhen. Some roads were blocked, trees were blown down and some buildings were damaged.
In addition, Typhoon Sura brought a lot of rain to Shenzhen. Heavy rainfall in a short period of time led to disasters such as water accumulation and waterlogging in Shenzhen city. Some low-lying areas have serious water accumulation, which affects the normal travel of citizens. In this regard, the Shenzhen Municipal Government promptly launched an emergency plan for flood control and drainage, and made every effort to carry out rescue work to ensure the safety of citizens' lives and property.
Impact of typhoon:
1. Strong wind: Typhoon with strong wind may reach instantaneous gust or even exceed hurricane level. Strong winds may cause trees to fall, buildings to be damaged, telephone poles to collapse, etc., resulting in property losses and personal safety threats.
2. Heavy rain: Typhoons are usually accompanied by heavy rainfall, which leads to intense heavy rain and persistent rainfall. Heavy rain may cause floods, resulting in water accumulation in rivers, roads and low-lying areas, which has a serious impact on traffic and residents' lives.
3. Storm surge and waves: Typhoon may cause strong storm surge and high waves when landing. Storm surge may lead to seawater intrusion in coastal areas, causing serious damage to coastline and coastal buildings. The rising waves may also cause potential safety hazards in maritime navigation, affecting ports and maritime traffic.
4. Soil liquefaction: Earthquake activity or heavy rainfall during typhoon may lead to soil liquefaction, which will affect the stability of land and may lead to geological disasters, such as landslides and land collapse.
5. Power outage: Strong wind and rainstorm may cause power facilities problems such as power line outage and transformer damage, which may lead to power outage. Power failure will have a serious impact on residents' life, transportation, communication and water supply infrastructure.
6. Farmland and crops are affected: Typhoon may also have a significant impact on farmland and crops. In particular, the destruction of crops such as fruit trees, vegetables and rice fields may lead to the reduction of agricultural output and the loss of farmers' income.
