Authorities in southeastern Arizona are putting residents on notice that they might have to evacuate because of a wildfire burning in the Huachuca Mountains.

Meanwhile, 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.

Firefighters are wrapping up containment on a 145-acre blaze outside of Flagstaff.

On the Huachuca Mountains, a 365-acre blaze is burning with no containment so far. Authorities were handing out pre-evacuation fliers to nearby residents Tuesday and encouraging them to pack a bag.
