West Virginia's worst flooding in a century has killed at least 24 people.
West Virginia's death toll from flooding is the highest for any US state this year, with 15 deaths reported in Greenbrier County in southeast West Virginia, where the heaviest rain fell, and six in Kanahwa County, officials said.
The death toll in West Virginia is the highest in any American state from flooding this year.
At least 16 people, including nine US soldiers, were killed in flooding in Texas earlier in June.
Up to 25.4cm of rain fell on Thursday (local time) in the mountainous state, sending torrents of water from rivers and streams through homes causing widespread devastation.
A state of emergency has been declared in 44 of 55 counties and deployed 200 members of the West Virginia National Guard on Friday to help rescue efforts. About 32,000 homes and businesses remained without power on Saturday.
Hundreds of people have been rescued and search and rescue teams were looking for more people on Saturday, officials said.
Some towns were completely surrounded by water and hundreds of houses and buildings have been lost.
