Crews assigned to the Bighorn Fire will continue their clean up work as they move toward significant increases in overall containment over the weekend, officials said Friday.

UPDATES: Bighorn Fire near Tucson, July 3: Here's what we know

The lightning-caused wildfire burning in the mountains north Tucson since June 5, had grown to 118,804 acres — about 185 square miles — according to a Friday morning update.

Though there has not been too much rain over the past two days, the significant rise in humidity has helped in firefighting efforts.

Despite being unable to get firefighters on the ground, the area south of Sabino is "ready for containment any day," Scott Schuster, an incident commander with the the Northern Rockies Incident Management Team, said Friday.

The perimeter of the wildfire from its southern edge above Tucson west and northwest to the Oracle area and east nearly to Redington is "looking excellent," Schuster said.

Crews also continue to make good progress fighting the fire near Redington, the busiest edge of the wildfire in the past few days. "There's still a little bit of work in there yet, but it's looking real good," Schuster said.

Firefighters were still working around the Summerhaven area, dealing with a 3-acre hot spot near Radio Ridge, but expect to cut back operations there within the next two days.

Some areas remained under mandatory evacuations Friday. They include:

â€ĸ The lower Catalina Highway and Mount Lemmon communities from Organization Ridge Road to Willow Canyon.

â€ĸ Mount Lemmon and Mount Bigelow, north of the Organization Ridge Road area, including Summerhaven.
