A massive fire whirl formed near Kanosh, Utah, as the Widemouth 2 wildfire burned through the Fishlake National Forest [1].

These rare atmospheric phenomena, often called "firenados," demonstrate the extreme volatility of large-scale wildfires and the danger they pose to first responders and nearby residents.

Paula Kaye McFarland captured the event on video while traveling north on I-15 [1]. The footage shows a towering vortex of smoke and flame swirling into the sky. This specific fire whirl occurred on July 28, 2024, at approximately 4 p.m. [2].

The Widemouth 2 fire was caused by lightning [3]. At the time the fire whirl was observed, the blaze had already burned more than 4,000 acres [4].

Fire whirls occur when intense heat from a fire combines with strong, shifting winds. This creates a rotating column of air that can pull flames upward into a spinning vortex [3]. The combination of the fire's own heat, and the surrounding wind conditions in Millard County, created the necessary environment for the whirl to form [1].

Witnesses said plumes of smoke filled the sky, creating a dramatic visual of the fire's power [1]. The event highlighted the unpredictable nature of the Widemouth 2 blaze as it moved through the national forest [2].

“A towering vortex of smoke and flame swirling into the sky.”

The occurrence of a fire whirl indicates a high-intensity fire with significant atmospheric instability. While rare, these vortices can accelerate the spread of a wildfire by lofting embers over containment lines, making the blaze significantly harder to control and increasing the risk to personnel on the ground.
