...A BAND OF LAKE EFFECT SNOW WILL AFFECT LEWIS...FAR SOUTHERN
CENTRAL JEFFERSON...AND NORTHERN OSWEGO COUNTIES...

At 514 AM EST, A band of lake effect snow producing snow fall rate
of 4 inches per hour was located from Mannsville and Pulaski inland
across central and southern Lewis county. This band of heavy lake
effect snow will begin to drift south over the next 1 to 2 hours.

Winds in excess of 40 mph are expected with this band of lake effect
snow, producing significant blowing and drifting snow and whiteouts.

Locations impacted include...
Oswego, Sandy Island Beach State Park, Lowville, Pulaski, Adams,
Redfield, Selkirk Shores State Park, Highmarket, Barnes Corners and
Southwick Beach State Park.

This includes Interstate 81 between exits 34 and 41.

Use extra caution if you must travel into or through this dangerous
snow squall. The combination of very heavy snow and blowing snow
will create very dangerous travel conditions with near zero
visibility and deep snow cover on roads. Some roads are likely to
become impassable. Consider delaying travel until the squall passes
your location.
