TUCSON, Ariz. — Hundreds of foothills homes on the outskirts of Tucson remained under an evacuation notice Friday as firefighters supported by helicopters worked to keep a wildfire from moving downhill from canyons and ridges in mountains in a national forest.
Most of the western United States is experiencing extreme dryness or drought, creating challenging conditions for wildfire season, Bryan Henry, meteorologist with the National Interagency Fire Center, said in a recent fire season outlook.
The Federal Emergency Management Agency granted Arizona’s request for money to help fight the fire, officials said Thursday.
Fire officials said the fire’s growth slowed overnight but that it remained a threat. Flames have been visible from Tucson at night, and smoke from the fire plumed over a suburb Friday morning.
Pima County officials on Thursday issued an evacuation notice for approximately 300 homes in a area south of the Coronado National Forest, and numerous other residents were told to prepare to evacuate.
Over 400 firefighters battled the week-old lightning-sparked fire that as of Friday had burned 11 square miles (29 square kilometers) of mostly brush and tall grass.
Fire officials said specialized crews were assessing potential threats to homes and other structures to identify access routes and develop contingency plans in the event of the fire spreading into neighborhoods.
In the neighborhoods closest to the fire, sheriff’s deputies checked IDs to confirm that people trying to enter were residents, as helicopters dropped water on hot spots.
Sheriff’s officials went door to door in neighborhoods on Thursday to notify residences of the evacuation notice, which a sheriff’s spokesman said Friday wasn’t mandatory.
“People are not required to leave, however we are telling people we may not be able to come back and assist if things start to burn,” said Deputy James Allerton.
No injuries or structural damage was reported, Allerton said.
Travis Mayberry, an operations section chief for the fire management team, said Friday much of the fire was burning in terrain too rugged for grounds crews to work safely, particularly if they needed to escape quickly.
“It’s not a great place for us to put people in to safely work,” he said. “It’s just too steep.””
Mayberry said crews continued to clear lines to keep the fire away from homes south of the forest and might set additional fires to burn vegetation to slow the wildfire by depriving it of potential fuel.
The fire, sparked June 5 by lightning, was only 10% contained as of Friday morning, and Mayberry said increasing the containment figure would be a slow process..
The dry, hot weather and the steep, rocky topography have been the main challenges in fighting the fire, fire management team Adam Jarrold said Thursday. Temperatures have pushed past 100 degrees (38 Celsius) and the humidity was in single digits.
