A powerful typhoon has caused at least 15 deaths in China and Taiwan just days before a second storm is expected to batter the region.

Chinese authorities say 13 people have died in the eastern provinces of Fujian and Zhejiang since Typhoon Meranti made landfall early Thursday, with another 14 people still missing. Taiwanese officials have reported two dead. A second typhoon, Malakas, is expected to hit Taiwan on Saturday before moving on to China.

Meranti this week lashed a vast swath of China's seaboard, including Shanghai, with heavy rain and winds of up to 280 kilometers per hour (175 miles per hour).

The typhoon made landfall in China's southeastern Fujian province, where media reports showed power lines toppled and streets submerged in water.
