At least six structures, including multiple homes, have been destroyed and mandatory evacuations have been ordered after a brush fire erupted in Weber Canyon Tuesday morning, authorities said. A helicopter crew with GPS surveyed the fire perimeter late Tuesday and found the fire has burned 619 acres. Earlier officials believed it had burned 1,200 acres. In addition to the homes, many other structures were being threatened, Layton Fire Marshal Douglas Bitton said. Video captured by KSL's Chopper 5 showed three homes heavily damaged or destroyed. Weber Fire District Fire Marshal Brandon Thueson said authorities have told residents east of U.S. 89 in Uintah to leave their homes. He estimated about 900 residents were evacuated. Streets in the evacuation zone include Bonneville Terrace Drive, Borg Circle, Bybee Drive, Combe Road and Karen Drive. "We anticipate the current evacuation orders for the Uintah Highlands area through the evening, possibly through the evening and into tomorrow," Thueson said. The fire also skipped I-84 and began threatening structures in South Weber, Bitton said. However, evacuations were lifted in South Weber and residents were allowed to return to their homes early Tuesday afternoon. Those impacted by the fire were told to report to the Dee Events Center, 4400 Harrison Blvd., in Ogden. The center was set to close at 8 p.m. Tuesday and reopen at 9:30 a.m. Wednesday, according to Weber State Police. Washington Heights Church, located at 1770 E. 6200 South in Ogden, said it also opened its doors to those affected by the fire.
