RALEIGH, N.C. (WTVD) -- During Thursday's severe weather, one passerby on I-440 witnessed a traffic sign fall on another car.
In the span of ten seconds, video shows rain blinding a driver along I-440. Then, panels of the Crabtree Valley/Glenwood Avenue exit sign get blown off the sign's stand by strong winds and hit a driver's car.
"It just came down like a torrential downpour," said Christopher Buchanan. "As it started getting worse, I noticed hail on the windshield and that's when I look up and saw the sign let loose into that BMW."
Gov. Roy Cooper issued an advisory Thursday afternoon.
"Everyone should remain alert to rapidly changing weather conditions and have a way to receive weather alerts from the National Weather Service," Cooper said in a written release. "Using a NOAA weather radio, or a smartphone app that provides emergency weather alerts for your location is a good way to stay informed."
