Local officials are also reminding drivers to be careful during their morning and evening commutes Wednesday.

Tina Gibbs, spokeswoman for PennDoT District 10, said anyone who doesn’t need to drive should avoid it, but those who encounter extreme difficulty while driving should consider additional precautions.

“Drivers just need to use some caution, drop their speeds a little bit, be aware of the conditions around them. If it’s bad and they need to pull off, do it in a safe area where you won’t be in the way of any cars or plows,” Gibbs said. “As always, we encourage, if (drivers) can stay home, stay home.”
