The National Weather Service has issued a freezing rain advisory for Ontario, Wayne, Livingston and Wyoming counties from 6 p.m. Saturday to 10 a.m. Sunday.
There could be accumulations of up to a quarter-inch of ice, according to the weather service. Ice will vary considerably by location; northern portions of the counties and higher terrain will likely be more prone to icing. The main impacts could be icing on trees and elevated surfaces and some slick spots on roads. Icing may result in some isolated power outages.
A flood watch is also in effect from Saturday afternoon through Sunday evening for portions of central and western New York, including Ontario, Wayne, Monroe and Livingston counties. Heavy rain and melting snow could result in excessive runoff and significant rises on area rivers and creeks, according to the weather service. There is also a risk of flooding of small streams and urban and poor drainage areas.
The weather service has also issued an ice storm warning for much of western New York on Saturday. The warning is in effect starting at 4 p.m. and will affect Monroe, Orleans, Erie and Niagara counties. The warning will remain in effect until noon Sunday.
The weather service urges people to use extreme caution if traveling in that area. The storm could also result in power outages.
