What weather hazards affect Zhejiang during late summer and early autumn?

During late summer and early autumn, the coastal regions of Zhejiang are frequently affected by devastating typhoons, which are tropical cyclones.1

These weather systems are a significant hazard for the province, as the southeastern coast of China experiences a high frequency of typhoon strikes between May and November, with the period from July through September being the most active. In Zhejiang specifically, these storms are a recurring threat during the late summer and early autumn months.21
