...A BAND OF LAKE EFFECT SNOW WILL AFFECT SOUTHWESTERN LEWIS AND
NORTHERN OSWEGO COUNTIES...
At 1020 PM EST, A band of lake effect snow producing snow fall rates
of at least 1 to 2 inches per hour was located from Pulaski to
Constableville on the northern end and from Mexico to West Leyden on
the southern end. This band will remain nearly stationary or
oscillate a little to the south through midnight.
Winds up to 30 mph are possible with this band of lake effect snow
which will create blowing and drifting to the snow. A rumble of
thunder is possible within the most intense portions of the snowband.
Conditions will deteriorate rapidly under the more focused band of
snow with visibilities under a quarter of a mile at times. Travel
will be very difficult with deep snow covered roads. This includes
Interstate 81 between exits 33 and 37. Other routes impacted include
Route 3 between Mexico and Pulaski and Route 13 between Pulaski and
Williamstown.
Locations impacted include...
Oswego, Sandy Island Beach State Park, Pulaski, Redfield, Selkirk
Shores State Park, Highmarket, Mexico Point State Park, Nine Mile
Point, Scriba, Richland, New Haven, Mexico, Williamstown, Orwell,
Sandy Creek, Lacona, Parish, Altmar, Constableville and Osceola.
