At least 14 people have been killed in China as Typhoon Soudelor hits the country, state media says.
At least four others went missing as some parts of the country were hit by the heaviest rains in a century, the Xinhua news agency said on Sunday.
Most of the casualties, 12 of them, were reported in and around Wenzhou city in the eastern coastal province of Zhejiang, where downpours caused mudslides and several houses collapsed.
Local disaster relief officials have told local media that the dead and missing may have been washed away by floods or buried under ruined homes.
Packing winds of up to 230 kilometers (roughly 143 miles) an hour, the typhoon was called the biggest of the year by the government.
About 1.58 million people in the city were affected with state officials estimating that the direct economic losses stood at 4 billion yuan ($644 million).
Two people were also killed not too far off Wenzhou, in the neighboring city of Lishui.
The Wencheng county, also in the same province, saw downpours of 645 millimeters (25.4 inches) in 24 hours after the typhoon made landfall on Saturday night.
The storm first landed in Fujian province and initially cut power to more than three million homes there, but more than a third had electricity restored by Sunday morning.
China's National Meteorological Center forecast the typhoon would be downgraded to a tropical depression by Sunday night as it moved further inland.
Before making landfall in China, Soudelor left six people dead in Taiwan, where it ripped up trees and triggered landslides, damaged electricity lines, and knocked out power to a record four million households.
Almost half a million homes were still without power Sunday as blocked roads hampered efforts to restore supplies in some areas, Taiwanese authorities said.
Some 379 people were injured by the storm in Taiwan, which saw rivers break their banks under torrential rain and towering waves pound the coastline.
