It was the fourth and most powerful typhoon to hit Taiwan this year.

An 82-year-old man was killed when he fell into a flooded rice paddy, and an 18-year-old girl was killed by a fallen electric wire in central Taiwan, the Disaster Relief Centre said.

Typhoons frequently hit Taiwan between July and October, causing flash floods and deadly landslides. Two weeks ago Typhoon Sinlaku killed 12 people and left 10 others missing and presumed dead.
