The large plume of smoke over Phoenix is coming from a big fire in an industrial area downtown.
The listed address, near the Interstate 10/Interstate 17 stack, is a distribution center for a company that sells electrical, welding, plumbing, and other industrial products.
The fire department has labeled the incident a hazmat situation, and according to one report, compressed gasses and other flammable materials were stored at this facility.
According to the Arizona Department of Transportation, I-10 westbound is closed at Seventh Avenue due to the fire.
Phoenix police are also restricting McDowell Road, west of Seventh Avenue.
