A small craft advisory is also in effect for rough conditions Saturday afternoon and Saturday night for L.I. Sound east of Port Jefferson, Peconic and Gardiners bays.

“A winter storm warning for heavy snow means severe winter weather
conditions are expected or occurring. Significant amounts of snow

emergency. If you must travel, keep an extra flashlight, food and water in your vehicle in case of an emergency.” the weather service said.
