Wildfire burning in Catalina Mountains near Tucson

A wildfire in the Santa Catalina Mountains put flames within view of Tucson residents overnight, with people in parts of the city and the Catalina Foothills able to see the glow from the ridgeline. The fire was reported near Finger Rock Trail, a popular access point in the mountains, and no structures were at risk as crews worked to contain it. By the following update, officials said the fire had grown to 67 acres but was 50% contained, offering reassurance to nearby neighborhoods while leaving the blaze active inside its containment lines.

The fire, identified by officials as the Finger Ridge Fire, began burning late Friday, Aug. 7, near Finger Rock Trail. Flames were photographed around 11:30 p.m. near East Skyline Drive and North Swan Road, giving residents along the Catalina Foothills a clear view of the incident. The location placed the fire on the south-facing side of the Santa Catalinas, close enough to Tucson for the flames to be visible across parts of the metropolitan area. Reports did not identify any damage to homes, businesses or other structures.

The origin had not been officially confirmed in the initial report Saturday morning. However, the fire appeared to have started during a night when several lightning strikes moved through the area. A time-lapse video recorded by a 13 News employee showed the storm, which officials and broadcasters identified as the likely cause of the fire. The storm also provided a striking backdrop for Tucson residents, with lightning visible in the sky even as the wildfire burned in the mountains.

The Coronado National Forest later provided a more detailed status update. Crews had made progress on the Finger Ridge Fire, bringing it to 50% containment while reporting that it covered 67 acres. Containment means crews had established lines around part of the fire, though it did not mean all flames or hot spots had been extinguished. Officials said the fire was expected to continue smoldering within those lines until forecast rain arrived and helped put out the remaining hot spots.

Finger Rock Trail was open for public use in the latest update. That status is significant for Tucson hikers and other visitors who use the Catalina Mountains, particularly because the fire was burning near the trail itself. The update did not report a trail closure, evacuation order or threat to structures. It also did not describe any injuries or property damage. Residents and visitors, however, could still see smoke or flames while the fire continued to smolder, and conditions could change as weather moved through the area.

The fire unfolded during Tucson’s monsoon season, when thunderstorms can bring both needed rain and lightning capable of igniting vegetation. In this case, the storm was believed to have started the fire, while forecast rain was expected to help firefighters finish the job. That created a complicated sequence for crews: lightning may have triggered the blaze, but precipitation from the same broader weather pattern was expected to suppress the remaining hot spots after the fire had been brought under control.

For people living near Skyline Drive, Swan Road and the Catalina Foothills, the overnight flames were a visible reminder that a fire in the mountains can quickly become a community concern even when no homes are immediately threatened. The reports did not include an official fire size or cause when the flames were first seen, and the Coronado National Forest had not issued that information by Saturday morning. The later acreage and containment figures supplied a clearer picture, showing a fire that had expanded to dozens of acres but was being managed without structures at risk.

The next step was continued monitoring and suppression within the containment lines, followed by the arrival of forecast rain. Officials expected the weather to extinguish the remaining hot spots, while crews continued making progress on the fire. Residents could follow updates from the Coronado National Forest and local broadcasters, and people who captured storm or fire images were encouraged by 13 News to share them. The available updates described a contained and advancing response, but not a fully extinguished fire, making the status of the Finger Ridge Fire dependent on conditions in the mountains and the effectiveness of the expected rainfall.
