Champaign, Illinois – Drivers across eastern Illinois are facing dangerous early-morning travel as dense freezing fog settles in, sharply reducing visibility and creating slick road conditions before sunrise.
According to the National Weather Service in Lincoln, dense freezing fog has developed across Champaign, Vermilion, Douglas, Coles, and Edgar counties, with visibility dropping below one-half mile at times. In some areas, visibility may briefly fall near zero, making travel especially hazardous on rural highways and less-traveled roads.
Temperatures below freezing are allowing moisture from the fog to freeze on contact, leading to icy patches on untreated roads, bridges, overpasses, parking lots, and sidewalks. Cities including Champaign, Urbana, Danville, Tuscola, Charleston, Mattoon, and Paris are all impacted. Drivers may encounter rapidly changing conditions over short distances, particularly near open fields and low-lying areas.
Illinois State Police and local emergency managers urge motorists to slow down, increase following distance, and use low-beam headlights when driving through fog. Sudden stops and lane changes should be avoided, as black ice may be difficult to see.
Conditions are expected to gradually improve later this morning as temperatures rise and fog dissipates, but officials warn that lingering slick spots could persist into the morning commute. Additional travel advisories may be issued if freezing fog redevelops.
