SUMMIT COUNTY — A massive aerial attack and targeted efforts by ground crews Wednesday helped prevent  the Flagstaff Fire from spreading toward Bouder’s western suburbs and enabled safety officials to lift pre-evacuation notices.

There has been no damage to any structures and no injuries from the fire.

The fire was held to about 230 acres with containment estimated at 30 percent. Thunderstorms also delivered some heavy rain to the area, raising the relative humidity in the vicinity of the fire.

Firefighters were able to establish secure fire lines to the west and south of the fire and using aerial drops of retardants to slow any potential advance.

Roving patrols are keeping an eye on the fire perimeter looking for spotfires.
