North Carolina Department of Transportation leaders are also urging people to stay off the roads through Sunday. They say fewer vehicles on the roads makes their job easier and people safer as conditions are expected to get slippery.
"This is going to be really treacherous, very slippery conditions and the ice is not going to go away this weekend because it's going to be below freezing all weekend," said Steve Abbott, a spokesperson for the NCDOT.

"There's not a lot that we can do in terms of pre-treatment so it's a lot about getting our crews rested and ready," said Andrew Sawyer, spokesperson for RDU.
He said they have crews have been on standby, ready to clear snow from runways, taxiways and parking lots. As far as planes go, he said airlines routinely de-ice their planes throughout winter.
