PHILADELPHIA (CBS)–From Spring Garden to the Parkway, most streets were deserted Tuesday night and the cleanup has started.

Seven-hundred city workers are out clearing streets and sidewalks and after hours of heavy snow some SEPTA buses were still running, but cars and cabs were making a slow go of city’s streets.

At a press conference Mayor Nutter said, “We want to strongly encourage folks to not be out unless you have to. This is a very serious storm, plummeting temps high winds makes this a dangerous storm.”

A city wide a snow emergency is in effect and emergency calls have been higher than normal, forcing the city to prioritize life threatening calls first.

Nutter said, “Please 911 is for an emergency only. We’re up 22 runs per hour over normal time.”

Non-essential city offices and city schools are closed Wednesday and Eyewitness News found plenty of kids and parents not wasting any time, celebrating the snow day with a bumpy ride down the art museum steps.

Dougherty says, “Twenty-five of us came down South Philly. We usually do it every big snow storm so we haven’t been able to do it in a couple years.”

What better way to celebrate a snow day than a bumpy ride down the Art Museum steps?
