Even though our nor’easter has departed from the East Coast, that doesn’t mean we’re fully out of the woods from the storm. Onshore winds coming from the north or northeast will continue to push water into the Northeast and Mid-Atlantic coasts through Sunday, making for a prolonged flood threat.

In the Mid-Atlantic, the worst flooding is still to come. That will occur during the Saturday morning high tide cycle from New Jersey southward through the Outer Banks of North Carolina. On the Outer Banks, minor flooding is forecast to occur through Sunday night whereas the flooding on the ocean-side of the DelMarVa up through New Jersey will experience several cycles of moderate flooding Saturday into Saturday night to then minor flooding Sunday into Sunday night. Thankfully, record flooding will not happen at any stations, but prone areas will likely flood during the high tide cycles this weekend. For the latest graph below, click here.

Now on Long Island and into New England, the coastal flooding situation will be worse than the situation in the Mid-Atlantic. Yes, there will be multiple high tide cycles that experience coastal flooding through Sunday night, but the inundation and storm surge will be more severe. Some areas along the eastern Massachusetts coast and on Cape Cod may experience more major flooding at the high tide cycle during the midday hours of Saturday. This is when three to six feet of storm surge is expected. On top of this surge will also be waves of up to 10 to 20 feet. Thankfully, the worst of the flooding in Boston occurred Friday and Friday night where a top three record crest of 14.67 feet was accomplished. Then for the next high tide cycles Saturday night through Sunday night, up to minor flood stage water levels will be reached as the winds taper off.
