Fire fighting teams tackled a blaze on Wednesday in northern Arizona, a couple of hours' drive north of Phoenix.

The wildfire, which started Tuesday, has grown to about 5,000 acres and has forced the evacuation of hundreds of homes outside Prescott.

Authorities say the blaze was likely caused by someone, and is under investigation.

The forecast for the next few days calls for hot and windy conditions.

That's prompted concern the fire could encroach on residential homes in this valley.
