In a special weather statement, the National Weather Service reports a heavy lake effect snow band is moving toward the western portion of Genesee County and could drop snow at a rate of three inches per hour as far east as Batavia.
Visibility will be near zero with winds gusting to 40 mph.
"Travel will be extremely difficult or even impossible due to a combination of snowfall and strong winds," warns the weather service.
UPDATE 6:17 p.m.: A medic with Mercy EMS informs dispatchers that conditions are so bad, "we won't be doing any transports to Buffalo until further notice."
