PennDOT has reduced the speed limit on several highways in the Philadelphia region due to the winter storm.

Speed has been reduced to 45mph on:

-Interstates 76, 95, 295, 476, 676.

-U.S. Routes 1, 30, 202, 422.

Pennsylvania Governor Josh Shapiro has signed a disaster emergency proclamation due to Sunday's major winter storm.

"Stay off the roads if you can, be safe, and follow instructions from PEMA and your local authorities," said Shapiro on Friday.

The disaster declaration allows the Commonwealth to quickly draw down funding and provide state agencies with the resources needed to assist counties and municipalities as with response efforts.

The snow began pre-dawn on Sunday, with the heaviest falling from sunrise until midday. This then transitions to sleet for the afternoon hours, as the sleet line marches northward from the Jersey shore to the Pa. Turnpike. Get the latest forecast at 6abc.com/weather.
