PHILADELPHIA (CBS) – Low pressure over southern Virginia continues to intensify this afternoon proving rain, snow and wind across the mid-Atlantic.

For the Delaware Valley, periods of rain will continue this afternoon into the evening along with very windy conditions.

Later this evening, a changeover to snow is expected from west to east and that will be the best chance for snow accumulations of around 2-4 inches, with the highest amounts west of Philly. These amounts could change either way depending on the temperatures, snowfall rates and time of changeover.

Winter storm warnings and winter weather advisories have been issued for parts of the region.

As the storm continues to intensify tonight, strong east to northeast winds will continue, gusting to near 60 mph along the coast and 50 mph inland.

This onshore wind flow will start to pile up water along the coast later tonight into Thursday.

A coastal flood warning is in effect for Delaware and New Jersey for possible moderate coastal flooding late tonight & Thursday morning.

High wind warnings are also in effect for coastal areas and wind advisories are in effect for inland locations. There are already numerous reports of trees and power lines down.
