OSWEGO COUNTY – The National Weather Service has issued a Lakeshore Flood Warning and a Lake Effect Snow Warning for Oswego County beginning Thursday, Feb. 27.

Lakeshore Flood Warning 

The Lakeshore Flood Warning will be in effect for Oswego and Jefferson counties Thursday at 10 a.m. until Friday at 11 a.m.  The NWS said the combination of high water levels and high waves will result in lakeshore flooding along the immediate Lake Ontario shore, especially in bays, inlets and other low lying areas. Some shoreline erosion will occur.

It warned to stay off breakwaters, piers, rock outcroppings and beaches. Waves are often larger than they appear and can easily wash you away. They expect significant black erosion and debris, local road closures and extremely dangerous boating conditions.

Lake Effect Snow Warning

The Lake Effect Snow Warning will be in effect for the Eastern Lake Ontario Region, including the cities of Oswego, Watertown and Lowville, Thursday at 7 a.m. until Saturday at 6 p.m. It expects long duration of heavy lake effect snow.

Total snow accumulations of 2 to 3 feet with locally higher amounts are possible in the most persistent lake snows. Snowfall rates may exceed 2 inches per hour at times. Winds could gust as high as 45 to 50 mph resulting in significant blowing and drifting snow.

The NWS said travel will become very difficult to impossible with very poor visibility and deep snow cover on roads. The hazardous conditions will greatly impact the morning and evening commutes. Gusty winds could bring down tree branches as well.

*** Lake Effect Snow Warning has since been replaced by the Blizzard Warning ***
