In the wake of the storm that brought snow and rain to the central Appalachians and areas east of the mountains Tuesday, colder air can lead to icy spots Wednesday morning.
As the snow diminished Tuesday afternoon and evening, a substantial amount of it melted on its own and made surfaces wet.
Early Wednesday morning, motorists and pedestrians should assume that any areas which appear wet may, in fact, be icy. Icy spots can form during the evening hours in some locations.
While in most cases roads will dry off due to traffic and treatment, there will be some exceptions. Not all surfaces, such as streets, secondary roads and sidewalks, may have be treated.
Clear ice, or black ice as it is often called, is transparent and causes the surface to appear wet.
Each year across the United States, there are hundreds of slip and fall incidents and auto accidents attributed all or in part by black ice, according to AccuWeather.com Forensics.
Light winds may prevent surfaces from drying. In some cases, ice can form with air temperatures above freezing.
No storms are forecast for the area during the balance of the week.
