Freezing fog in the Charleston, S.C. Lowcountry early Friday created hazardous driving conditions on major highways like I-26, U.S. 17, and I-95 until 8 a.m. Bridges, overpasses, and untreated roads developed a thin ice glaze, with low visibility near waterways.
Affected Areas
The advisory covered Charleston metro and inland parts of Berkeley, Dorchester, Colleton, and Allendale counties. Key spots included I-26 from Summerville to downtown Charleston, U.S. 17 near Mount Pleasant and Walterboro, U.S. 52 near Moncks Corner, and I-95 ramps near Point South. Communities like Goose Creek, Moncks Corner, Walterboro, Allendale, and Beaufort faced risks on sidewalks and parking lots too.​
Safety Tips
Slow down, increase following distances, and avoid sudden braking on slick surfaces that ice first. Light ice could form on vehicles, trees, and guardrails where fog freezes on contact. Conditions improve post-sunrise as temperatures rise above freezing.​
Outlook
Fog dissipates after sunrise Friday with drier air arriving, ending further winter hazards that day. Isolated slick spots may linger briefly on shaded bridges.
