A winter storm warning has just been issued by the National Weather Service in Buffalo. (It upgrades yesterday's winter storm watch.)
It's in effect 10 a.m. Sunday through 4 a.m. Tuesday. Heavy snow is expected in Orleans, Genesee and Ontario counties.
Hazards include snow possibly mixed with sleet and freezing rain on Sunday south of the Thruway.
Accumulations of two to three inches of snow Sunday; three to five inches Sunday night; two to four inches Monday; and one to two inches Monday night. Storm total of nine to 13 inches.
Winds 10 to 20 mph. Visibility as low as half miles at times.
Long-lasting accumulated snow will produce difficult travel and hazardous driving conditions, with snow-covered roads and reduced visibility.
Severe weather is expected. Motorists in the warning area should use an alternative route if possible or use extreme caution if travel is unavoidable.
If you lose power and plan to run a generator, be sure it is located outdoors and is properly ventilated. Space heaters should also be properly ventilated and used only if operating properly. Make sure snow does not block exhausts and fresh air intakes for high efficiency furnaces and water heaters.
