Here is how to help victims of the flooding in Kentucky.

Search-and-rescue efforts continued across much of southeastern Kentucky on Friday after what Gov. Andy Beshear said was “one of the worst, most devastating flooding events” ever to hit the state.

Mr. Beshear warned that the death toll would rise and would include children. The flooding caused power outages, made many roads impassible and knocked houses off their foundations.

“The people impacted by this are going to lose just about everything,” Mr. Beshear said at a news conference on Friday, adding that officials believed that thousands of people had been affected by the flooding.

Here are some ways to help the victims.

The Team Eastern Kentucky Flood Relief Fund, which was established by Mr. Beshear, is accepting tax-deductible donations online and by mail to help people who were affected by the floods.

The American Red Cross in Kentucky said it was working with local emergency management officials to assess needs in about nine counties. The organization is taking donations to help in the recovery.

The Kentucky Department of Agriculture is accepting donations of bottled water, toiletries and nonperishable food. The collection site is 105 Corporate Drive, Suite A, in Frankfort, the state capital. The department is accepting donations from 8 a.m. to 4:30 p.m. on weekdays through Aug. 5.

The Appalachian Regional Healthcare Foundation Flood Relief Fund is accepting monetary donations online to help provide victims with generators, transportation, food, water and access to health care and medicine. The organization is also accepting donations of cleaning supplies, nonperishable food and water at its office at 2260 Executive Drive in Lexington.

The Foundation for Appalachian Kentucky, a nonprofit community group in Hazard, Ky., said it was accepting donations through its Crisis Aid Fund.
