Kentucky on watch for more tornadoes

Just three weeks after deadly tornadoes, a state of emergency has been declared in Kentucky as powerful storms ripped through the state causing flash floods, power outages and property damage.

The tornadoes in December tore through the region, killing more than 90 people in five states, including 77 in Kentucky.

As of Saturday afternoon, much of Kentucky was under a flood warning. Portions of eastern Kentucky, as well as swathes of Tennessee, Arkansas, Louisiana, Mississippi and Alabama were under a tornado watch.

The Kentucky governor's office reported flash flooding had caused water rescues and many road closures in the southern and central portions of the state.

In the southwestern town of Hopkinsville, several downtown businesses were damaged by a possible tornado. Local TV reported a store had been largely destroyed and the roof of a gas station had blown into a park across the street. Other nearby buildings had roof damage and there were many downed power lines, the station reported.

Another possible tornado touchdown occurred in Taylor County, in the middle of the state, where a number of homes were damaged, according to the governor's office.

Heavy rains were expected to continue throughout the day in much of Kentucky, followed by a cold front, which could complicate emergency response efforts.
