At least eight people were confirmed dead Thursday after heavy rains caused massive flooding across eastern Kentucky, leaving people stranded on rooftops and others without power or water as forecasts call for even more rain. 

Kentucky Gov. Andy Beshear said he expects deaths to rise into the double digits, calling it one of “the worst, most devastating flooding events” in state history. He said forecasted storms Thursday evening and into the weekend mean the impacts could worsen, potentially hindering both rescue efforts and work to restore power and water.

“This is an ongoing disaster that continues to put people in danger,” Beshear said Thursday evening. “Our death toll is growing, … and a lot of families out there have lost absolutely everything.”

Beshear declared a state of emergency for all of Kentucky, and the National Guard has been mobilized. 

“We probably have not seen the worst of it,” Beshear said. “Sadly, we believe that we will lose Kentuckians and a lot of Kentuckians will probably lose most of what they have.”

Gen. Hal Lamberton of the Kentucky National Guard said crews were working to rescue people stranded on the roofs of homes. Staff at a school were also stranded, he said. 

More than 6 inches of rain fell overnight heading into Thursday morning, leaving streets underwater. Several inches were expected Friday and forecasters with the National Weather Service warned heavy rains and flooding could continue throughout the weekend. 

In Perry County, 20 people were unaccounted for early Thursday, said Deputy Sheriff Scott Sandlin. The region had been hit with major flooding, with several bridges and roads covered in water and other structures destroyed, he said. 

An 81-year-old woman from Perry County was one of those who died in the flooding, Beshear said. Information on the seven other victims was not immediately available.
