Kentucky Gov. Andy Beshear braced the commonwealth’s residents for some somber news overnight as emergency responders continued work following tornado destruction.

Beshear said it’s likely that western Kentucky’s death toll may exceed 50 people.

The governor shared the disturbing estimate during a phone interview with WLKY-TV of Louisville.

Beshear said a single tornado tore across the state in a sustained way for more than 200 miles.

Other nearby towns were also hit, he said.

“We know that we’re likely to have more than 50 deaths, if not significantly north of that, from this event,” Beshear told the station.
