>>Photos: Fireworks storage containers go up in flames
Emergency crews were called around 5:45 a.m. to the fireworks storage containers near Davey Jones Fireworks along Carowinds Boulevard, just off Interstate 77.
Shells and rockets burst through the metal containers, sending colorful showers into the air above Davey Jones Fireworks and the House of Fireworks.
WSOC crews on the scene could see flames and smoke billowing from the area.
York County deputies said the fire was not actually at the fireworks store but started in containers just outside the store.
Viewer video sent to WSOC showed the fireworks shooting into the sky and exploding just before dawn.
