The National Weather Service has issued a new Winter Weather Advisory from 6 p.m. today until noon Friday.

The main problem will be black ice and ice-covered secondary roads.

A Winter Weather Advisory for Black Ice means that refreezing of roads will occur, resulting in the development of widespread black ice. Be prepared for very slippery roadways. Some roads that appear clear may be covered by a thin layer of ice.

We already know the county is changing its Friday schedule: Rowan County Government offices will be on a 1-hour delay for Friday and will open at 9 a.m. See all alerts and sign up to be notified when alerts are added/updated at rowancountync.gov/AlertCenter.as
