LOUISVILLE, Ky. (WDRB) -- Wind chills around 0 degrees will arrive in Louisville early Friday morning behind the snow, John Gordon, a meteorologist with the National Weather Service, said Thursday.

Around 2 inches fell at Louisville Muhammad Ali International Airport, but areas south of the city received more. Many portions of Interstate 65 in Bullitt County experienced traffic issues Thursday afternoon as the roads got slick after as much as 7 inches of snow fell.

"Slow down," said Vanessa Burns, director of Louisville Metro Public Works. "We saw a number of people today that are still driving like the middle of summer."

Louisville Mayor Greg Fischer said city crews sprayed brine on major roads Tuesday and Wednesday in preparation for the storm. Crews began salting city roads Thursday morning before the snow fell, and Fischer said they'll treat the roads as long as necessary and there's plenty of salt to do so. The city said it started the year with 38,000 tons of salt, more than half of which is stored underground in the Louisville Mega Cavern.

“... I’m asking residents to stay off the roads and for essential workers to take extra precautions if they must travel,” Fischer said in a news release. “With colder temperatures like those expected in the coming days, there’s great potential for dangerous slick spots and black ice on roadways.”

Burns added that public works crews will put brine and calcium chloride on roads in an effort to prevent precipitation from freezing. To get a real-time look at what roads have been treated in Louisville, click here.

Fischer said 62 of the authorized 450 Public Works staff are either out because of a positive COVID-19 case or quarantine. That amounts to about 14% of the force, but they will be rolling back as available, he said.

Louisville Metro Police said there were 24 injury crashes and 120 non-injury crashes between 10 a.m. and 4 p.m. Thursday. 

Fischer said his administration is in talks with the Coalition for the Homeless and other city agencies to keep the homeless community safe. He said Operation White Flag, which kicks in when the temperature drops below 35 degrees, is in effect at Wayside Christian Mission, St. Vincent de Paul and the Salvation Army Center.

Participating shelters will fly a white flag outside of their doors to indicate that White Flag is occurring," the city says on its website. "You may remain inside of the shelter as long as the flag is flying outside."
