PHILADELPHIA (CBS) — All Philadelphia public and archdiocesan schools, as well as administrative offices, will be closed tomorrow and transportation officials are urging you not to drive if you don’t have to.

Philadelphia plows and salting trucks are mounting a snow removal operation that is expected to last well into Thursday.

A snow emergency is in effect until 7 a.m. Thursday in most places in the Philadelphia area. That means no parking on snow emergency routes overnight so crews can be sure to clear those major arteries. Philadelphia alone has 450 vehicles on duty.

It will be another week of long overtime for city streets department crews, and Mayor Nutter says they’ll keep at it until all city streets, including the side streets, are cleared:

“We’re in the business of fighting snowstorms. We’ll do whatever it takes to make sure the streets are as clear as possible and the citizens are as safe as possible.”

Septa says the Broad Street and Market Frankford lines will work through the night too but service is suspended on most suburban routes and many city routes.

“The city will work hard through the night and into the morning to make sure streets are plowed and they’re safe for folks to drive on,” said Deputy Managing Director Liam O’Keefe.

At the airport, spokesperson Victoria Lupica says crews are at work too.
