I-85 and I-26 near Greenville, South Carolina – Travel across the Upstate could become hazardous this weekend as a significant winter storm brings a mix of snow, sleet, and freezing rain to the region, with ice posing the greatest threat to road conditions.
According to the National Weather Service in Greenville–Spartanburg, a Winter Storm Watch remains in effect from 7 a.m. Saturday through 1 p.m. Monday for much of Upstate South Carolina, northeast Georgia, and western North Carolina. Forecasters warn that widespread winter weather impacts are likely, including hazardous driving and potential power outages.
Accumulation probability graphics show a 30–50% chance of at least 0.5 inches of ice across portions of the Upstate, including areas near Greenville and Spartanburg. Even smaller ice amounts can create slick, dangerous roads, especially on bridges, overpasses, and untreated surfaces. Snow and sleet accumulations of 4 inches or more remain possible farther north, while ice and sleet are more likely to dominate locally.
Major roadways including I-85, I-26, I-385, and U.S. 29 could see rapidly deteriorating conditions beginning Saturday, worsening Saturday night into Sunday as colder air deepens. The Weather Service cautions that moderate winter storm impacts may include road closures, traffic disruptions, and infrastructure issues, especially where ice accumulates.
Light rain is expected today ahead of the storm, but temperatures will remain above freezing until colder air arrives this weekend. Once freezing conditions set in, travel conditions may deteriorate quickly.
Drivers are urged to avoid unnecessary travel Saturday night through Sunday, prepare vehicles for winter conditions, and monitor forecast updates closely as precipitation type and amounts may change.
Commuters, students, and weekend travelers across the Greenville metro area should prepare for dangerous travel conditions and possible disruptions.
