Forecasters say small amounts of snow and sleet will fall in the upper reaches of South Carolina Monday afternoon, but the weather will change to freezing rain by evening.
The National Weather Service does not expect much more than one inch of snow along the northern counties that border North Carolina: Oconee, Pickens, Greenville, Spartanburg, Cherokee, and York counties. Much of the Piedmont will get a wintry mix, but no accumulation is expected. The heaviest ice is expected to stick to trees and power lines in areas around Greenville, Spartanburg and Rock Hill and points north.
The winter weather warning is in effect until Tuesday morning.
Forecasters expect around a quarter-inch of ice. A half-inch is the threshold where widespread power outages can be expected.
Much of the Savannah River and Lakelands region was hit by a heavy ice storm last year that knocked out power for an estimated 348,000 customers and created an estimated 2.5 million cubic yards of debris from fallen tries and limbs.
According to the Associated Press, the Upstate’s last major ice storm was in December 2005.
