The Harley Fire has burned 199 acres in Box Elder County, leaving portions of Tremonton and Garland without power as investigators determine the fire was human-caused. As of August 22, 2026, fire crews have achieved 25% containment and are working to protect remaining areas from further spread.
Infrastructure and Road Disruptions
The fire, which officials say was human-caused, has caused significant disruption to local infrastructure and transit. According to Utah Fire Info on August 22, 2026, power has been shut off in the affected area, resulting in reported outages in parts of Tremonton and Garland. On Harley Drive, power remains out as repair crews continue their work.
In addition to utility disruptions, the fire has necessitated several road closures to ensure public safety and allow emergency personnel access. Harley Drive remains closed and under evacuation orders, while Radio Hill has been placed in a ready status. On August 21, 2026, Utah Fire Info reported that Canal Road and 7600 West remained closed to all through traffic. While northbound lanes on I-15 remain open, southbound lanes were closed during the height of the fire's activity.
Containment and Fire Growth
Containment efforts are ongoing as firefighters battle the perimeter. As of August 22, 2026, the fire has reached 199 acres, with crews reporting 25% containment. Firefighters are currently focused on patrolling the perimeter, mopping up hot spots, and monitoring the blaze to prevent further expansion.
Earlier in the incident, on August 21, 2026, Utah Fire Info estimated the fire at 150 acres. During that period, crews were working to establish a dozer line around the perimeter to hold the fire against approaching strong winds and a developing storm system. Despite the spread of the flames, officials confirmed on August 22 that no primary structures have been lost to the blaze.
Regional Fire Weather Risks
The wildfire activity follows a period of heightened fire weather risks across the region. A National Weather Service forecast from August 7, 2026, had warned of dangerous heat intensifying across the Desert Southwest and Intermountain West. At that time, the forecast noted that hot, dry weather and increasing winds would allow elevated wildfire conditions to return to the northern Intermountain West.
The atmospheric conditions described in the August 7 forecast included the potential for increased wildfire activity due to persistent air quality issues from ongoing fires and the combination of hot, dry weather and increasing winds.
Power Utility Safety Measures
Rocky Mountain Power has noted that emergency de-energization is a standard procedure used when an active wildfire is present. This measure is intended to prevent further wildfires from being ignited by power lines. However, these safety protocols can lead to more frequent outages for customers as wildfire risk increases.
The utility company has advised customers that when enhanced safety settings are in place to prevent wildfires, there is an increased potential for outages. In such cases, customers may experience longer-than-typical outages as field crews must patrol the lines thoroughly before power can be safely restored. Residents with electricity-dependent medical needs are encouraged to contact the utility to discuss available accessibility programs.
Public Safety and Support
An evacuation center has been established at the Garland Armory to assist those displaced by the fire. Local authorities continue to urge the public to avoid the area to give emergency crews sufficient room to work and to ensure that all evacuation instructions are strictly followed.
