Nov 9, 7:00 PM Nov 11, 7:00 PM
WHAT: Heavy lake effect snow possible. Total snow accumulations
between 4 and 7 inches possible.

WHERE: Crawford, Northern Erie, and Southern Erie Counties.

WHEN: From 7 PM EST this evening through Tuesday evening.

IMPACTS: Visibilities may drop below 1/4 mile due to falling and
blowing snow. Snowfall rates may exceed 1 to 2 inches per hour
within well organized lake effect snow bands. The gusty winds and
weight of snow on tree limbs may down power lines and could cause
sporadic power outages. Travel could be difficult. The hazardous
conditions could impact both the Monday morning and evening
commutes as well as the Tuesday morning commute.

ADDITIONAL DETAILS: There may be an elevated risk for scattered
power outages due to trees in the local area still having most of
their leaves. The combination of leaves on trees and heavy wet
snow may bring down large branches on to power lines during this
early lake effect snow event.
