The entirety of Delaware is under a winter storm watch and the National Weather Service is warning of the possibility of significant snowfall Friday into Saturday.
The main threats are anticipated to include high winds which may lead to downed trees and power lines, extreme cold, snow, and minor coastal flooding.
A gale warning is also in effect for coastal areas and the Delaware Bay.
According to a report from NWS Mount Holly, significant snow accumulations of 6 inches or more are probable Friday night through Saturday afternoon. Strong winds may result in blowing and drifting snow and very low visibility. Dangerous travel is probable. Accumulating snow may be heavy enough to result in hazardous travel along the I-95 corridor including Wilmington, Philadelphia,
Trenton, and the suburbs.
Minor coastal flooding is possible along the Atlantic coast of Delaware and along the Delaware Bay Saturday morning.
Northeast to north winds 20 to 25 mph with gusts 40 to 50 mph are possible, which may result in some tree damage and power outages. Low wind chills on Saturday night will bring potential for rapid onset of frostbite on exposed skin in New Jersey and Delaware, as well as the southern Poconos and far northwest New Jersey Friday night through Saturday night.
Gale force wind gusts along with dangerous seas are probable in Atlantic coastal waters including the Delaware Bay Friday night through Saturday night.
According to the National Weather Service station at Mount Holly, a winter storm is forecast to affect much of the region Friday night and Saturday. Confidence in the storm total snow forecast is very low, owing to continued large uncertainty with the track of the associated surface low. There remains potential for significant snow accumulations of 6 inches or more across portions of the region. The highest snow totals are expected south and east of the I-95 corridor, with a sharp gradient to lower amounts near and north/west of there. Strong winds will be possible from Friday night through Saturday night. The strong winds may cause blowing and drifting snow and very low visibilities, especially near the New Jersey and Delaware coasts. Wind chills will be well below zero Saturday night, with values below -15 possible in the southern Poconos and far northwest New Jersey. Minor coastal flooding is possible Saturday morning along portions of the NJ and D coasts, including Delaware Bay. Marine hazards include gale-force wind gusts along with dangerous seas Friday night through Saturday night.
