PHILADELPHIA -- As efforts continue to dig out after a storm dumped 22.4 inches of snow on the city, Mayor Jim Kenney vowed that the city would be open for business come Monday morning, according to a report from CBS3.

"Mother nature threw us this curve ball, she does that now and then, and I think we responded quite well," Kenney declared in a Sunday morning press conference on the city's response to the powerful storm.

The snowfall is the fourth largest in city history. The 22.4-inch reading was recorded at the airport, according to the National Weather Service.

The city typically receives 22.4 inches of snow in an entire season.

A snow emergency declaration remains in effect for Philadelphia. Any cars parked on snow emergency routes will be towed, city officials noted.

Philadelphia International Airport is gradually resuming operations, according to 6ABC.

SEPTA has restored some services, but regional rail remains shut down as track clearing continues.
