More than two million people were evacuated from China's financial hub, Shanghai, before a powerful typhoon barrelled into the country's east coast early on Wednesday.
Residents from the city's exposed areas were moved to safety ahead of Typhoon Wipha's arrival.
Families and children waited anxiously in temporary disaster shelters, preparing to sit out the storm.
Schools and some offices in the city of 17 million people were closed while flights were grounded as Shanghai braced itself.
Experts labelled Wipha a "super typhoon" and warned it could bring 200mm of rain and winds of 200km/h.
Fears the storm could ravage Shanghai have disrupted the Women's World Cup, which the city is hosting.
Experts warn that it could be the worst storm to hit China since 1997, when Typhoon Winnie claimed 236 lives.
