Firefighters have achieved 100% containment of the Broad Fire in Weber Canyon, ending a week-long battle against the 145-acre blaze that began on Sept. 5, 2026. The incident was officially deactivated from monitoring maps on Sept. 10, following several days of work to extinguish remaining hotspots in the difficult terrain of Davis and Weber Counties.
Fire Origins and Size
The Broad Fire, located near Mile Marker 89 on I-84 near Ogden, was initially reported as having 0% containment on Sept. 5, 2026, according to data from the Northern Utah Interagency Fire Center. While the fire's size was initially estimated at 145 acres, subsequent updates indicated the blaze stabilized at 134 acres during the middle of the suppression efforts.
Difficult Terrain and Hotspots
During the height of the fire's activity, the terrain presented significant challenges for ground crews. On Sept. 8, 2026, Utah Fire Info reported that the fire remained at 50% containment with 134 acres burned. Firefighters faced steep and rocky landscapes that made accessing heat sources difficult, requiring crews to hike into the area to work on hotspots.
On that same day, reporter Jennifer Collett noted that while forward progression had been stopped on all fronts, the remaining uncontained line could take several days to fully extinguish due to internal pockets of flame and visible smoke. Crews were tasked with working the northern perimeter, which was identified as the uncontained edge of the fire.
Traffic and Public Impact
The fire's impact on local infrastructure and visibility was notable during the peak of the incident. On Sept. 7, 2026, Utah Fire Info reported that the fire was highly visible from Uintah, including the Uintah Highlands, as well as from I-84 and South Weber. The smoke and visible flames were particularly concentrated on the north side of the fire.
High holiday traffic in the canyon caused congestion on I-84, leading fire managers to open both westbound lanes to maintain traffic flow, though the shoulder remained closed. Officials issued reminders to the public not to call 911 to report the fire, as dispatch was receiving numerous calls regarding smoke and flames on the mountain.
Aerial Suppression and Weather
Air support played a critical role in the suppression efforts. Throughout the week, firefighters utilized water drops from multiple helicopters to cool hot spots along the active perimeter. On Sept. 6, 2026, Utah Fire Info noted that despite a lack of direct rainfall on the fire, a passing storm brought increased humidity and cooler temperatures, which assisted crews in managing the blaze.
By Sept. 8, 2026, containment had reached 80% as crews continued to work the northern perimeter. Despite the progress, officials warned that visible smoke and potential internal flames would remain until the fire was completely extinguished.
Final Status and Cause
As of Sept. 10, 2026, the incident was deactivated from the Watch Duty map, signaling the end of the active fire emergency. The cause of the Broad Fire remains undetermined by the Division of Forestry, Fire and State Lands.
