Pallets behind a Walmart in Imperial Beach caught fire Thursday afternoon causing a large fire that began spreading to vegetation.
The fire started at about 10:50 a.m. at the Walmart just off Interstate 5 and Palm Avenue.
Several crews responded to the scene, where a pile of pallets was sending up heavy flames. The fire was starting to burn vegetation behind the Walmart, but crews doused flames before they could spread, footage from SkyRanger 7 shows.
By about 11:30 a.m., the fire was nearly out and the pile of pallets was covered in white fire retardant.
