A cold front moving across Long Island on Thursday and stalling slightly during the evening hours brings mostly sub small-craft advisory conditions, the National Weather Service said in its marine forecast.
Winds from the southwest at 5 to 10 knots and waves at 1 foot or less are likely for most waters, the service's Upton office said. Some gusts to 20 knots are possible Thursday afternoon.
Even as the cold front moves north and a warm front moves in, bringing a chance of showers and thunderstorms, conditions remain well below small-craft-advisory levels through Monday, the service said.
Coastal water temperatures run from 58 to 59 degrees on the South Shore to slightly cooler at Montauk Point, according to the service.
New York Harbor registered 64 degrees, Willets Point 63 and Kings Park 62.
