PRESCOTT, Ariz. – More than 70 homes are under and evacuation order 14 miles south of downtown Prescott. The Goodwin Fire has already scorched over 400 acres and is still zero-percent contained.

"The winds have been erratic all day long, so it's been difficult for the firefighters to get in to where they needed to get in,” Cheyenne Warner, a spokesperson for Prescott National Forest Fire says.

Five air tankers were in constant rotation carrying retardant from a runway at Prescott Fire Center to the blaze roughly 14 miles south.

"These things are incredibly effective in helping slow down that fire progression,” Warner says.

The fire spread quickly from the time officials first heard about a small blaze near Pine Flat.

"It was only a 20 by 20 square foot block and then within a couple hours it spread to about 50 acres,” says David Mcatee with Yavapai County.

About 24 hours after the first report of fire, the blaze spread to nearly 500 acres.

The American Red Cross has set up a shelter for evacuees at Mayer High School, but most families choosing to stay elsewhere. The evacuation order is currently a precautionary measure and the flames are burning in a rural area.

"We haven't lost any structures at this point, and we're going to keep a real close eye on it,” Mcatee says.

The cause of this fire is still under investigation.

Officials originally said the fire was burning 1,000 acres, but released an updated number after surveying the flames from the air.
