The advisory runs from noon to Thursday evening, covering Moriches Inlet to Montauk Point; Fire Island Inlet to Moriches Inlet; Sandy Hook, New Jersey, to Fire Island Inlet; Peconic and Gardiners bays and South Shore bays from Jones Inlet through Shinnecock Bay.

The advisory also includes Long Island Sound east of Port Jefferson, but starts a bit later at 2 p.m.

For beachgoers, there's a high risk of rip currents through Thursday evening for ocean beaches of Long Island and New York City, the service said.
