Freezing rain is expected across central North Carolina starting overnight Wednesday. Duke Energy says the winter weather may cause nearly one quarter of its North and South Carolina customers to lose power.
Governor Roy Cooper has issued a state of emergency ahead of the storm. The order activates 40 members of the North Carolina National Guard to help with any tree or debris removal.

The governor's office says the state Department of Transportation has poured more than 30,000 gallons of brine on main roads throughout the state, but the agency is warning against driving in icy conditions.
The National Weather Service in Raleigh has issued a winter storm warning from the Triad to parts of the Triangle, including Durham, Guilford and Vance counties. A winter weather advisory is in effect for counties just south of I-85, including Wake and Chatham counties.
"Anything over a quarter of an inch of ice accumulation is enough to bring down a tree branch, which can cause significant damage to our infrastructure and our power lines," said Archie.
Forecasters expect a tenth of an inch to a quarter of an inch in the Triangle, and half an inch in the Triad. Weather.com says that a quarter-inch of ice can be disruptive to power lines, and a half-inch of ice accumulation can add 500 pounds of extra weight on power lines. National Weather Service meteorologist Nick Petro says ice accumulation could range from a tenth of an inch in Raleigh to half an inch in Greensboro.
“Half an inch of ice causes a lot of problems,” Petro said. “Imagine all the tree damage and power outages that occurred last week with three-tenths. In many places, this will be twice as much ice as we had last week.”
Petro says the Sandhills and coastal plain could get as many as three inches of rain, which could cause flooding along rivers that are already swollen from rain earlier this week.
Winter Storm Watch has been expanded and is in effect for Wednesday night through Thursday Evening for the northern Piedmont along and north of Interstate 85. Significant Ice Accumulations up to a quarter of an inch is possible. If possible, limit travel during this time. #NCwx pic.twitter.com/jQpom2Hv7d— NWS Raleigh (@NWSRaleigh) February 16, 2021
COVID Vaccine Delays
Winter storms making their way across the U.S. will likely delay the shipment of COVID-19 vaccine to North Carolina this week. State health officials got the alert from the Centers for Disease Control and Prevention on Tuesday.
Multiple news outlets are reporting that the state is working with providers to minimize disruptions to vaccination clinics. North Carolina had 3,167 new COVID-19 cases on Wednesday.
After the freezing rain eases, river flooding and localized flash flooding is expected. Some rivers are already in flood stages, including the Cape Fear and Lumber rivers.
The expected freezing rain comes after a tornado tore through Brunswick County late Monday night, killing three people, injuring 10 people and destroying several homes.
According to the National Weather Service, it’s supposed to be sunny during the day Wednesday, but temperatures will be about 10-15 degrees colder than it was on Tuesday. Weather.com predicts temperatures dropping to as low as 29 degrees in Durham by 5 a.m. Thursday.
