...NEAR BLIZZARD CONDITIONS EXPECTED TONIGHT ALONG THE LAKE ERIE
SHORELINE OF SOUTHERN ERIE AND CHAUTAUQUA COUNTIES...

Near blizzard conditions are expected along the Lake Erie shoreline
tonight, with the worst conditions expected between 1000 PM and 400
AM. Snowfall rates are expected to peak between 1 and 2 inches per
hour, along with northerly winds gusting to 45 mph. This will likely
create very dangerous and near impossible travel conditions, with
near zero visibility and blowing and drifting snow.

This includes Interstate 90 between exits 61 and 57A, or between the
Pennsylvania State Line and Eden-Angola.

Locations impacted include...
Dunkirk, Fredonia, Evans, Eden, Westfield, Silver Creek, Angola,
North Collins, Lake Erie State Park and Derby.

Visibilities will drop quickly to near zero in this area of heavy
snow.

Conditions can deteriorate rapidly in winter weather situations. Be
prepared for snow covered roads. Slow down and allow extra time when
traveling.
