LOUISVILLE, Ky. (WDRB) -- A wintry mix of freezing rain and snow overnight left streets and vehicles in Kentucky and Indiana covered with snow and ice early Thursday. 

As sleet and freezing rain began falling late Wednesday afternoon, extra crews were out in force in Kentuckiana to treat the roads. In Louisville about 200 crew members worked overnight to treat more than 100 roadways throughout the city. In Crescent Hill, about a half-inch of freezing rain fell, and Bardstown had about three-tenths to fourth-tenths of an inch.

The winter storm dumped significant amounts of freezing rain, sleet, snow and ice to Kentucky and Indiana. Kentucky Gov. Andy Beshear announced a state of emergency Thursday morning, a move that lets agencies better coordinate their responses. 

No storm-related deaths or injuries had been reported as of around 10:30 EST Thursday morning. The Kentucky National Guard has been put on alert but not activated, Michael Dossett, the state's emergency management director, told reporters at a press conference. 

About 7,500 homes and businesses in Kentucky were without power as of mid-morning, with a larger share of outages in the central and eastern parts of the state. In eight counties in northeastern Kentucky, more than 20 percent of customers were waiting for power to be restored. 

Dossett said winds expected to gust up to 25 miles per hour later Thursday could cause more downed tree limbs and power lines, worsening the outages in some areas. 

About 2,000 state workers and contractors are clearing roads, Kentucky Transportation Secretary Jim Gray said, but he added that routes in general are hazardous. 

In Christian County in southern Kentucky, I-24 West was closed Thursday morning and numerous other roads have been blocked, Gray said. He urged people who need to travel to "please, please be cautious."
