FLAGSTAFF, Ariz. (AP) -- Authorities in southeastern Arizona are putting residents on notice that they might have to evacuate because of a wildfire burning in the Huachuca Mountains.
The Brown Fire started Sunday and is burning in the upper elevations of the mountains overlooking Sierra Vista. There is no containment on the 366-acre blaze.
On Tuesday, authorities were handing out pre-evacuation fliers to residents in the area of Ramsey Canyon and encouraging them to pack a bag.
Firefighters are wrapping up containment on a 145-acre blaze outside of Flagstaff. The Fisher Fire was first reported Friday afternoon. It's confirmed as human-caused but a specific cause hasn't been determined as an investigation continues. Containment was at 90 percent Tuesday afternoon.
Officials in northern Arizona are preparing to enact fire restrictions in Flagstaff and on national forests. The restrictions go into effect Friday, about a month earlier than normal.
An ongoing drought has left the state even more vulnerable to wildfires. Nearly 270 wildfires have charred about 1,000 acres across Arizona this year. Most of those are small and human caused.
