With ocean waters expected to produce waves of 5 feet or more through Wednesday, a small craft advisory is in effect for Long Island's South Shore, the National Weather Service said in its marine forecast.

The advisory runs from noon to midnight and includes New York Harbor, the service's Upton office said.

Winds over Long Island Sound and Peconic and Gardiners Bays should be slightly weaker, the service said, with those zones rating sub small craft advisory conditions.
