Raleigh, NC – North Carolina drivers traveling through the state's mountain communities can encounter dangerous highway conditions when fast moving snow squalls suddenly reduce visibility to near zero. As winter weather awareness efforts continue Wednesday, Oct. 28, motorists are being reminded that brief bursts of heavy snow and gusty winds can create hazardous travel conditions within minutes.
According to the National Weather Service NWS , snow squalls are short lived, intense bursts of snowfall accompanied by strong winds and rapidly deteriorating visibility. These conditions can quickly cover roadways, reduce traction and increase the risk of multivehicle crashes.
How Snow Squalls Threaten North Carolina Highways Unlike prolonged winter storms, snow squalls can arrive suddenly, leaving drivers little time to respond before visibility drops and pavement becomes slippery.
Interstate 40, Interstate 26, Interstate 77 and U.S. Route 421 are among the major travel corridors where sudden snowfall could create hazardous driving conditions during winter weather events.
Motorists traveling through Buncombe, Haywood, Watauga, Avery, Ashe and Alleghany counties may face additional risks along elevated highways, steep mountain grades and exposed roadways.
Western North Carolina is particularly vulnerable to rapidly changing winter conditions, especially across the Blue Ridge Mountains and higher elevations near Boone, Banner Elk and Asheville.
What Is a Snow Squall Warning? The NWS issues Snow Squall Warnings when dangerous snow squalls are occurring or expected to develop shortly.
These warnings generally last 30 to 60 minutes and may activate Wireless Emergency Alerts on compatible mobile phones.
A warning signals an immediate threat to motorists, particularly those traveling at highway speeds where sudden visibility loss can contribute to chain reaction crashes.
What North Carolina Drivers Should Do When a Snow Squall Warning is issued, the safest option is to delay travel until conditions improve.
Motorists already traveling should:
Reduce speed gradually and increase following distance. Turn on headlights to improve visibility. Avoid sudden braking or abrupt lane changes. Exit the highway safely before entering dangerous conditions when possible. Never stop in an active travel lane during a whiteout. Residents can monitor forecasts and official warnings through the NWS Greenville Spartanburg office , NWS Blacksburg office and NWS Raleigh office , which serve different portions of North Carolina.
Winter weather awareness messaging continues through Saturday, Oct. 31, as part of this preparedness series, emphasizing how quickly snow squalls can transform mountain highways into dangerous whiteout conditions.
