市三防专家表示 “桦加沙”将带来三重主要风险

Core Viewpoint - The article discusses the potential risks posed by Typhoon "Haikashan" to Shenzhen, highlighting extreme winds, tidal surges, and heavy rainfall as the main concerns [1] Group 1: Extreme Wind Impact - The typhoon could make landfall with a strength of level 16, leading to significant wind damage over a larger area, particularly threatening high-rise buildings, glass facades, cranes, outdoor billboards, and street trees [1] Group 2: Tidal Surge Risk - The timing of the typhoon coincides with the lunar calendar's third day, which may result in astronomical tides. The combination of the typhoon and high tides could elevate sea levels, increasing the risk of coastal flooding in low-lying areas [1] Group 3: Heavy Rainfall Impact - It is expected that Typhoon "Haikashan" will bring approximately 300 millimeters of rainfall to Shenzhen. This, combined with storm surges, may lead to drainage issues in rivers such as the Shenzhen River, Maozhou River, and the Pearl River estuary, potentially causing flooding in coastal low-lying regions [1]
