Winter weather update: Icy conditions remain for Lowcountry. Here’s how to stay safe on SC roads
While the snowfall is over and warmer temperatures are on the way, much of the coastal and Lowcountry areas of South Carolina are experiencing hazardous conditions following the wintry weather.
According to the National Weather Service, colder than usual temperatures will remain through Thursday and Friday.
The cold weather advisory will lift at 10 a.m. Thursday, with a daytime high of 38 degrees and a low of 23 degrees.
Temperatures will rise a bit higher on Friday and through the weekend, with highs in the mid to upper 40s and nighttime lows in the 20s and 30s.
Even though the storm has passed, the biggest concern now for local law enforcement and transportation agencies is the refreezing of snow and slush as temperatures dip during the night.
These conditions have created the risk of black ice on the roads, which is a thin, transparent coating of ice that is notorious for creating dangerous and slippery conditions for those out on the roads.
Both Beaufort and Jasper County Sheriff Offices have advised and warned residents to stay off the roadways during the evenings but even in the daytime, shady areas can stay frozen in the cooler temps.
The risk of refreezing and black ice forming is expected to remain over the weekend but if you must drive, here are some safety precautions to take before getting behind the wheel.
What is black ice?
Black ice is one of the most dangerous driving hazards in the area. It is often not easily spotted by drivers due to how it forms on the ground.
Typically, it freezes clear enough that the road surface below can be seen, thus leading to its name.
Since temperatures drop to their lowest during the night, black ice is most prevalent during the morning hours, when most are on their way to work.
According to the NWS, black ice is a concern for South Carolina drivers Thursday morning, then again Thursday night into Friday morning.
Advisory messages on Thursday morning from Beaufort and Jasper County state that even though roads are beginning to clear, black ice has developed in some areas.
Both Beaufort and Jasper County law enforcement offices are advising residents to use extreme caution.
What should I do if I see black ice?
If you have to drive over the next few days on any roads, here are some precautions to take before getting onto the road and what to do if you do drive over black ice.
Black ice often forms in smooth, glossy sheets. So, if you spot a shiny, glossy patch on an otherwise dull, black road, that’s an indication of black ice.
According to the United States Forest Service, if you do hit black ice, take your foot off the gas and let your car pass over it.
They state that you should not hit your brakes and keep the wheel straight. Steering in the opposite direction may risk you skidding or spinning out.

Other safety tips when driving in icy conditions
Wipe all ice and show off your car including the windows, the hood and the roof. There is a risk of it sliding off your vehicle when driving, which can cause damage to you and other drivers.
Defrost all windows before driving to avoid any sight issues and leave the defrosters on if you can.
Scrap ice off of any windows, if you don’t have an ice scraper you can use other tools like a rubber squeegee, soft bristle brush or even a credit card (just remember to scrub gently to avoid scratching or damaging your windows).
Follow all road closure signs. As conditions continue to change, follow all law enforcement signs and warnings.
Use your headlights in low visibility.
Prepare your vehicle for icy travel: This includes checking the tire pressure, battery, wiper blades and fluids. It is also advised to keep an emergency kit in the car that includes blankets, snacks, water and a battery just in case.
Drive slowly and cautiously by staying at a reduced speed and staying a safe distance away from other vehicles on the road.
Avoid sudden stops, sharp turns or using cruise control on icy roads.
