PennDOT officials are telling drivers to stay off the roads unless it’s absolutely necessary.

State crews are prioritizing high traffic routes and those leading to health care facilities.

If you have to be on the roads -- slow down and give all vehicles on the road extra space.

The Pennsylvania Emergency Management Agency says they’re concerned about shipments of the COVID-19 vaccine that will be traveling through the state during the storm. And they’re planning to monitor shipments to help make sure the vaccines make it to their destination, which is just one more reason why they want you to stay off the roads.

UPDATE (4:45 PM):

Officials are becoming concerned about icy conditions going into the evening commute.

Jason Winters, Hempfield Township manager, said ice is always a concern.

“And making sure we have enough material on the road to combat the ice and making sure any late night commutes are okay, but we should be fine for morning commute tomorrow.”

Overall about 3-5 inches of snow have fallen in eastern Westmoreland and Fayette counties

UPDATE (4:30 PM):

Slick roads are the big concern for PennDOT crews this evening as more snow could come in the next few hours. Crews have been working 12 hour shifts since this morning, and don’t plan to stop anytime soon.

“We are anticipating more snow today and tonight. So our crews will be out in force, maximum effort plenty of material, our operators in trucks are in good shape,” Jay Ofsanik with PennDOT said. “Our plow drivers will be out there throughout the day throughout the evening and into the early morning hours until this event is over.

UPDATE (11:00 AM): Cars in Pittsburgh neighborhood get stuck while waiting for plow truck

Some people in the Overbook section of Pittsburgh have been stuck in snow, waiting for a plow or salt truck to come through.

A Channel 11 News crew spent most of Monday morning on Line Street after they were stuck while checking road conditions in the area.

Linda Chardello also became stuck sideways on a hill. She sat in her car for nearly two hours waiting for a plow truck to come around, but it never did.

After getting tired of waiting, she left her car and the Channel 11 crew helped her up the hill.

“Terrible. That’s like that all the time,” said Chardello.

“Forty-five years and this has always been a mess here for some reason,” said resident Richard Matthews.

One resident didn’t even try to drive to work. Instead, he decided to walk to the T station.

UPDATE (10:40 AM): Two-man crew works to clear roads in Alleppo Township

Alleppo Township only has two salt trucks, so their two-man crew has been working around the clock since yesterday to clear the roads.
