Tropical Storm Trami struck Taiwan yesterday after battering the Philippines earlier this week.
More than 1,000 tourists have been evacuated from the surrounding islands and some flights were suspended in preparation for the storm.
The centre of the storm was offshore, 100km northeast of the capital, Taipei. The storm was expected to head westward to the Chinese province of Fujian.
Nine injuries were reported and 5,000 homes were left without power.
Earlier this week Trami hit Manila, leaving 15 dead, 41 injured and affecting more than one million people as floodwater swamped the region.
Heavy rains are expected to continue today. The high speed rail system, which links Taipei to the southern city of Kaohsiung, has been suspended.
