Floodwaters from Typhoon Bavi swept cars through the streets of Chengde City in Hebei province on July 12 [1].

The storm's impact underscores the vulnerability of northern China's urban infrastructure to extreme weather events. As torrential rains continue to batter the region, the risk of landslides and further urban flooding remains high.

Authorities in Chengde and surrounding areas issued a red alert as the storm brought heavy rain and strong winds [2]. Officials said residents should stay indoors to avoid the rising flood risks [2]. Video footage from the region showed floodwaters surging through neighborhoods, burying some areas in debris, and carrying vehicles away in the current [1].

The scale of the emergency response has been significant, though reports on the total number of displaced residents vary. Some reports indicate that more than 260,000 people were evacuated [3]. Other estimates suggest the number of evacuees exceeded 1 million [4], while some sources said nearly 3 million people were moved to safety [3].

Typhoon Bavi has threatened eastern China with several days of continuous heavy precipitation [5]. The storm's path has created a critical situation in Hebei province, where the combination of saturated soil and intense rainfall has overwhelmed local drainage systems. Local authorities continue to monitor water levels in reservoirs and river basins to prevent further catastrophic failures.

Emergency crews remain deployed in Chengde to assist stranded residents and clear debris from primary roadways. The red alert remains in effect as the storm system moves through the region, with meteorologists saying that the most dangerous period of rainfall may not yet have passed [2].

The wide discrepancy in evacuation numbers—ranging from 260,000 to nearly 3 million—suggests a chaotic early reporting phase or a massive, tiered evacuation effort spanning multiple provinces. The severity of the flooding in Chengde highlights the persistent challenge China faces in managing 'urban flooding' despite significant investments in drainage infrastructure.
