A nor’easter packing strong winds, plenty of snow (more than a foot is possible in some neighborhoods) and potential flooding is set to pound the Philadelphia region Tuesday.

A Winter Storm Warning is in effect for most of the region while a Blizzard Warning is in effect for Berks, Chester, Lehigh, Montgomery, Northampton and Hunterdon counties.

In New Jersey and Delaware, a Coastal Flood Warning is in effect for Atlantic, Burlington, Cape May, Ocean and Kent counties while a High Wind Warning is in effect for Atlantic, Burlington and Cape May counties.

Governor Tom Wolf declared a state of emergency for Pennsylvania while Governor Chris Christie declared a state of emergency for New Jersey. All state offices will be closed in Pennsylvania and New Jersey Tuesday.

All School District of Philadelphia schools, administrative offices and after school activities as well as all Philadelphia Archdiocesan high schools and parochial elementary schools will be closed Tuesday due to the storm.

Most of the area should see snow with occasional rain and sleet possibly mixing in as the storm intensifies after moving in before midnight. The snow begins south and west quickly moves north and east.

The heaviest snow should fall in the morning with the far northern and western suburbs, the Lehigh Valley and Berks County getting the most snow – most likely 1 foot or more – with the Delaware Beaches and Jersey Shore likely seeing mostly rain, wind and possible flooding.

In Philadelphia and the immediate suburbs snow could turn to sleet then to rain and back to snow again during the storm.

Wind (gusts could break 40 mph) and the heavy snow could combine to bring down budding tree limbs and power lines. Beach erosion and coastal flooding are also concerns, especially during high tide.

Ahead of the storm municipalities declared states of emergency and made “Code Blue” declarations.

Much of the region is under a Winter Storm Warning through Tuesday afternoon with Ocean County facing a Blizzard Warning.

9 to 10 p.m. Monday: snow begins
10 p.m. Monday to 3 a.m.: snow begins to pick up
3 a.m. to 11 a.m.: heaviest accumulation
