248 WWUS41 KPHI 052040 WSWPHI URGENT - WINTER WEATHER MESSAGE National Weather Service Mount Holly NJ 340 PM EST Mon Mar 5 2018 ...A major snowstorm is on the way for portions of our area on Wednesday... .Unfortunately, a major nor'easter will be intensifying rapidly Wednesday afternoon along the New Jersey coast. It is expected to produce heavy wet snow for eastern Pennsylvania and portions New Jersey Wednesday. Highest amounts should be in the hilly areas. While this storm is still in watch phase, we recommend everyone with activities in eastern Pennsylvania and New Jersey to have contingency plans for altering travel and how to handle possible power related impacts. These plans can then be applied once warnings are issued, which will express more confidence in this oncoming probable very high impact event. Wednesday may be a good day to just stay home and be safe.
