Typhoon Bavi generated a powerful storm surge that slammed into windows and buildings in Taizhou city on Saturday [1].
The event highlights the vulnerability of China's eastern coastline to sudden surges, even as storm systems lose peak intensity before making landfall.
The storm hit Taizhou, located in the Zhejiang province on the eastern coast of China, on July 12 [1], [2]. Low pressure and strong winds pushed large waves onto the shoreline, causing significant damage to coastal structures [3]. Video footage showed the surge crashing directly into windows of buildings along the coast [4].
Reports on the storm's strength varied at the time of the impact. Some descriptions characterized the system as possibly the most powerful storm in years [5]. However, other reports indicated that Typhoon Bavi had weakened to a tropical storm by the time it reached the coast [6].
The storm surge occurred as part of a broader weather system that threatened the region with several days of heavy rain [2]. Local authorities in Zhejiang province monitored the shoreline as the surge impacted the urban infrastructure of Taizhou [1], [2].
Despite the weakening of the wind speeds, the displacement of water remained a primary threat to the city's waterfront. The combination of high tides, and storm-driven waves created the conditions that breached residential and commercial windows [3], [4].

The discrepancy between the storm's classification as a tropical storm and its destructive surge demonstrates that wind speed is not the only metric for danger. Storm surges can cause catastrophic structural damage regardless of whether a system maintains typhoon-strength winds, posing a persistent risk to densely populated coastal hubs like Taizhou.
