Typhoon Soulik has made landfall in Taiwan, bringing strong winds and torrential rain to the island.
So far one person is reported to have died while 21 have been injured in the extreme weather.
More than 8,500 people have been evacuated from mountainous and other dangerous areas and thousands of soldiers have been deployed.
Soulik is set to arrive in mainland China's eastern provinces of Fujian and Zhejiang later on Saturday.
Local authorities there have been asked to implement emergency response plans, China's state-run news agency Xinhua reported, after recent torrential rain across large parts of the country reportedly left 200 people dead or missing.
Typhoon Soulik, a medium-force typhoon, had wind speeds of around 173 km/h on Saturday morning.
A police officer was killed by falling bricks but other people suffered mostly light injuries, including from fallen trees or being blown off their scooters.
The strong winds and heavy rain have caused electricity disruptions, a run on food and essential supplies in supermarkets, and uprooted trees and signs in some areas.
There had been fears of major damage because the island was the first place it made landfall, reports the BBC's Cindy Sui in the capital Taipei.
Nearly 50,000 soldiers have been put on standby, she says.
Schools and offices in Taipei and several other cities had closed on Friday afternoon as the tropical storm neared.
