Officials warn of coastal flooding, high tides, and 20-foot waves in parts of Long Island and NYC

State officials said the greatest flooding risk will coincide with morning high tides and that the full moon could make tides higher than usual. "The worst flooding is expected to be during this morning's high tide along the Southshore and we're seeing that right now in real time cameras," the Governor said while describing shoreline impacts in New York Harbor and along the Long Island Sound.

Officials listed neighborhoods where residents should be especially cautious, naming Rockaways, Coney Island and Broad Channel in New York City and Atlantic Beach, Freeport and Lindenhurst on Long Island. The Governor described visible flooding at locations such as the Battery, where video feeds showed water on the boardwalk.
