...A BAND OF LAKE EFFECT SNOW WILL AFFECT CAYUGA AND OSWEGO
COUNTIES...

At 336 PM EST, a plume of heavy lake effect snow producing snow fall 
rates up to 2 inches per hour is located over far northern Cayuga 
county and the western half of Oswego County. 

As this area of snow moves eastward across Oswego County it will 
create poor visibilities and snow covered roads. If traveling be 
prepared for these greatly reduced visibilities as well as slippery 
spots on snow covered roads. 

Additional light to moderate snow is expected to continue into the 
evening hours southeast of Lake Ontario. 

Locations impacted include...
Oswego, Fulton, Fair Haven Beach State Park, Central Square, Mexico
Point State Park, Nine Mile Point, Battle Island State Park,
Hastings, Scriba, Volney, Constantia, West Monroe, Palermo, Sterling,
New Haven, Phoenix, Minetto, Mexico, Williamstown and Cleveland.

 This includes Interstate 81 between exits 32 and 35.
