Two separate fires broke out near 43rd Avenue and Indian School Road in Phoenix and spread to multiple businesses Thursday night, reports azcentral.com.
Firefighters from across the Valley were helping to knock down the flames in what appeared to be an industrial area.
Motorists and pedestrians have been advised to avoid the area between 43rd and 36th avenues, Indian School Road and Clarendon Avenue.
Authorities deemed the area dangerous, in part, because of a large amount of burning tires and toxic smoke, said Mark Vanacore, a spokesman for the Phoenix Fire Department.
Vanacore said the entire block was affected by the blaze and numerous structures and businesses were lost.
A cause was not immediately available and Vanacore said he could not confirm if the fires were weather related.
As of 10 p.m., officials said no injuries were reported.
At the same time, the city was also experiencing heavy 911 call volume times due to multiple incidents across the Valley, according to a tweet by Sgt. Steve Martos, a spokesman for the Phoenix Police Department.
