Nearly a week has passed since flooding devastated eastern Kentucky, and residents are readying to face a new hurdle: Forecasted heat and humidity is set to hit affected areas and impact those who still don’t have electricity, running water or permanent housing.

What happened: At least 37 people have died in what the governor called “one of the worst, most devastating flooding events in Kentucky’s history.” Many people are still unaccounted for after nearly a foot of rain last week led to intense flash floods, sweeping away houses and stranding residents on roofs.

“It’s absolutely devastating out there, it’s going to take years to rebuild,” Gov. Beshear said Tuesday morning. “People left with absolutely nothing, homes that we don’t know where they are … just gone.”

What the forecast means: The weather stayed largely dry overnight from Monday into Tuesday, and the possibility of new storms is diminishing, Beshear said at a Tuesday morning news conference. But high temperatures and humid conditions forecasted for Wednesday and Thursday are creating new obstacles for thousands of residents who no longer have power or water or who are in temporary housing.

Here’s what we know.

Cooling centers set up amid forecasted heat

Temperatures are expected to range from the mid 80s to 90 degrees Wednesday and Thursday, but a mass of humid air is likely to make it feel even hotter, according to the National Weather Service. Heat indices, meaning how the temperature feels to a person, could peak just over 100 degrees in some areas.

“It’s going to get really, really hot, and that is our new weather challenge,” Beshear said.

Beshear said the state was creating eight cooling centers for those in need, including the 9,686 customers still without power.
