Kentucky is combating washed out roads, destroyed homes and flooded schools, according to the governor.

Thousands of residents are expected to lose their homes, he said.

More than 294 people have been rescued from floodwaters in eastern Kentucky so far and that number will likely rise, Beshear said.

The rain may return to Kentucky late Sunday through early next week, but significant rainfall isn't expected.

"While rain totals are not expected to be as high, flooding still remains a concern due to saturated grounds," the governor tweeted.

President Joe Biden approved a disaster declaration and is receiving updates "very regularly," White House press secretary Karine Jean-Pierre said Friday.

"Our hearts break for the families of those who have lost their lives or are missing, and to all those who have been impacted," she said.
