Strong winds are hurting the fight against the Sawmill Fire and crews estimate the wildfire is between 17,000 and 20,000 acres wide. It's burning 10 miles southeast of Green Valley, which is south of Tucson.
About 100 residents have been evacuated and several more communities are under pre-evacuation orders.
State Route 83 is closed north of Sonoita, just south of Interstate 10.
Hundreds of firefighters are working to fight the flames on the ground, but air tankers have been grounded due to windy conditions.
