UPDATE: At 8 a.m. Monday, Yates County Undersheriff Howard Davis issued a travel advisory for all of Yates County until this evening. Heavy snow and strong wind conditions have made travel very difficult and some roads impassable. Highway crews are out and plowing. However, strong winds are causing considerable drifting and occasional whiteout conditions.

Sheriff's officials recommend that unnecessary travel should be avoided until the advisory is canceled. 

The National Weather Service in Binghamton has issued a Lake Effect Snow Warning in effect until 7 p.m. Monday for an area that includes Yates County.

Hazards include lake effect snow and strong gusty winds with blowing and drifting snow. Total snow accumulations are expected to be between 8 and 12 inches by daybreak with locally higher amounts. With a nearly stationary heavy snow band, some additional accumulations are likely on Monday.

An oscillating band of heavy snow continues to extend from Yates County to Southern Seneca, Eastern Schuyler, Southern and Western Tompkins, Tioga, and into Southern and Western Broome Counties. Hourly snowfall rates have been 1/2 to 1 inch with this band with occasional rates of 2 inches per house.

The heavy snow will make travel very difficult and some roads impassable. Isolated power outages may also occur due to the heavy snow and strong winds.

A Lake Effect Snow Warning means significant amounts of lake effect snow showers typically align themselves in bands and will likely be intense enough to drop one to several inches of snow per hour for several hours. Visibilities vary greatly and can drop to zero within minutes. Travel is strongly discouraged. Commerce could be severely impacted. If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency.
