* WHAT…Heavy lake effect snow. Additional snow accumulations of 10
to 20 inches today. An additional 10 to 15 inches is possible
Sunday through Monday. This would bring the storm total snowfall
for this event to 4 to 6 feet, with highest values across the
northern portion of the county.
Additional snow accumulations up to 42 inches.
* WHERE…Northern Erie and Southern Erie Counties.
* WHEN…Until 7 AM EST Tuesday.
* IMPACTS…Roads, and especially bridges and overpasses, will
likely become slick and hazardous. Visibilities may drop below 1/4
mile due to falling and blowing snow. Whiteout conditions are
expected and will make travel treacherous and potentially
life-threatening. Travel is impossible and should be postponed.
The hazardous conditions could impact the Monday morning and
evening commutes, especially along I-90 and I-86.
* ADDITIONAL DETAILS…Heavy lake effect snow is expected to
continue into Tuesday with snowfall rates of 1 to 2 inches per
hour. The highest accumulations are expected along the I-90
corridor and north with totals quickly decreasing to the south.
There is a potential for a brief lull in snowfall this evening
into the overnight hours as the heaviest band pushes north over
Lake Erie before returning on Sunday. The warning will continue
through this lull to account for the ongoing significant impacts
and the likelihood of continued blowing snow. People should avoid
travel unless absolutely necessary.
