Nor’easter Triggers Coastal Flood Warnings Across Northeast for Monday High Tides

Water levels will track the timing of a shift from northeast to north winds.

Overview

  • The National Weather Service issued a coastal flood warning for Hudson, Bergen, Essex and Union counties in New Jersey from 10 p.m. Sunday to 2 a.m. Monday, calling for 1 to 2 feet of inundation in vulnerable shoreline areas.
  • Suffolk and Nassau counties in New York are under a coastal flood advisory Monday from 11 a.m. to 6 p.m., with up to 1.5 feet of inundation expected in low-lying waterfront locations.
  • Forecasters note additional minor to locally moderate flooding is likely with the Monday afternoon high tide in parts of Long Island.
  • Massachusetts has coastal flood warnings through Tuesday morning for Plymouth, Barnstable, Martha’s Vineyard and Nantucket, where 2 to 3 feet of inundation is possible, while Essex, Suffolk and Norfolk counties have advisories for up to 1 foot.
  • An earlier wind shift to the north could lower water levels relative to forecasts, and ice in bays and harbors could worsen flooding and damage north- to northeast-facing shoreline structures.
