Typhoon Haikui has hit eastern China, the third such storm to make landfall there in a week.
The storm came ashore in Zhejiang province early Wednesday bringing heavy rains and winds of up to 150 kilometers per hour.
Zhejiang officials have evacuated more than 130,000 people, while in Shanghai, just to the north, about 200,000 of the city's 23 million residents have been moved.
Some 30,000 boats have been at port since Sunday in anticipation of the storm. All outdoor group activities have been banned. City parks and summer classes are cancelled, and outdoor construction has stopped.
The two earlier storms, typhoons Damrey and Saola, also hit Zhejiang, causing flooding and landslides. Authorities say 23 people were killed and nine were missing.
The typhoons not only affected China, but other countries surrounding the South China Sea. This week, the Philippine capital of Manila experienced landslides and flooding in the wake of Typhoon Saola. Thousands have had to leave their homes, and at least 50 people in the region have been killed.
