The National Weather Service has announced a Winter Weather Advisory for all of Long Island starting at midnight on Sunday and lasting until 6 a.m. Tuesday for what the NWS is referring to as a "long duration winter weather event" as a result of Winter Strom Marcus, which will include freezing rain and light snow of up to one inch.  Around a tenth of an inch of ice is expected, which will cause hazardous driving conditions.

A small craft advisory is in effect from 4 a.m. to 6 p.m. for the Long Island Sound east of Port Jefferson, and for Peconic and Gardiners Bays. A gale watch is also currently in effect for Monday evening through late Monday night.  Northeast winds of 15 to 20 knots are expected, with gusts of up to 25 knots earlier in the evening on Monday, but reaching up to 35 knots later in the night.  Western waters off of Long Island will also be affected - a small craft advisory has been announced from 11 a.m. Monday to 6 a.m. Tuesday for waters west of Port Jefferson and the South Shore bays from Jones inlet through Shinnecock Bay.  Gusts will similarly be 15 to 20 knots and gusts reach as high as 30 knots. Mariners are encouraged not to travel during these advisories.
