LOUISVILLE, Ky. — Following this week's historic winter storm, crews from Louisville Metro's Snow Team remain hard at work, with more snow expected in the next 24 to 36 hours, said Mayor Craig Greenberg, D-Louisville. 

During a Thursday afternoon news conference, Greenberg said the Snow Team has operated 24 hours a day since Sunday, working 12-hour shifts. Cleanup continues on the 110 primary snow routes, and most are complete; however, Greenberg acknowledged some aren't yet in perfect shape. Crews are also prioritizing Jefferson County Public Schools routes and those near the University of Louisville. 

"Use caution because there are still some areas with the freezing cold temperatures that we have that are not perfect," he said. 

He urged those who see a snow route that isn't in great condition to call Metro311. This follows what Greenberg said was the largest snowstorm to hit Louisville in more than 25 years. 

"Most of them are complete, but there are some that are needing attention and are getting attention," Greenberg said.

Greenberg said Louisville Metro plans to reevaluate its snow routes after this week. He said while English Station Road in eastern Jefferson County isn't part of a snow route, it should be, along with Bluegrass Avenue in the South End. 

Louisville Metro has used more than 30 million pounds of salt this week, Greenberg said. Crews have spent the last day moving salt from underground storage to snow domes so they can be prepared for tomorrow's snow. They are not using brine on the streets as temperatures are too low for that to be effective. 

Greenberg said he expects the snow to start in the morning, with the heaviest falling between 3 p.m. and midnight. Spectrum News 1 meteorologists said much of Kentucky will receive 2 to 5 inches of snow, with higher amounts likely in the southern part of the state. A Winter Storm Warning goes into effect on Friday at 4 a.m. eastern and expires Saturday at 7 a.m. eastern. 

The mayor added he has activated an emergency contractor for additional snow assistance starting Friday morning, and there will be 12 additional crews on top of Metro snow teams. Cars parked on emergency snow routes should be removed by midnight. Greenberg also urged Louisvillians to clear their sidewalks.

"If you are the property owner, it is your responsibility to maintain and shovel your sidewalks," Greenberg said. 

As for JCPS, Greenberg said he expects the district to decide on whether classes will be back in session “later this afternoon or evening.” The Transit Authority of River City will also continue operating on reduced routes through Sunday, Jan. 12.
