Tuesday’s powerful nor’easter lived up to its billing of unpredictability, tracking west and sparing Long Island from high snow accumulations — but pushing concerns about wind damage, power outages, flooding and erosion to the forefront. The Long Island Rail Road was operating on a weekday schedule, with storm-related delays.

Coastal flood warning: A coastal flood warning is in effect along Atlantic Ocean beachfront and the south bays of western Long Island, with widespread flooding expected around the times of high tide, the weather service said. The weather service predicted tides of 2 1⁄2 to 3 1⁄2 feet above astronomical tides and localized flooding related to the height of the storm tide and wave action. Along Atlantic Ocean beaches, high surf of 6 feet to 10 feet was expected to cause significant dune erosion and some washovers.

Until 1:15 p.m.

Flood advisory: Minor flooding in poor drainage areas of southern Nassau County and western Suffolk County is expected because of the combination of rain and melting snow. The weather service said communities that could be affected include Baldwin, Freeport, Long Beach, Lynbrook, Massapequa, Oceanside, Valley Stream and Woodmere in Nassau, and Babylon and Lindenhurst in Suffolk.
