At 813 AM EST, a snow squall was located near Cato, or 13 miles
south of Fair Haven Beach State Park, moving south at 10 mph. This
squall will move south through 9 AM this morning, rapidly reducing

of snow is possible with this squall.
Locations impacted include...

Central Square, Weedsport, Cato, Brewerton, Hastings, Constantia,
West Monroe, Gorham, Palermo, Phoenix, Rose, Ira and Conquest.
This includes the following highways...

are likely to lead to accidents. Consider delaying travel until the
squall passes your location.
Conditions can deteriorate rapidly in winter weather situations. Be
prepared for snow or ice covered roads. Slow down and allow extra
time when traveling.
