"Wildfire season" in Wyoming typically occurs between June and September, but wildfires can occur as early as April and late as December. Peak time of fire season is normally in July and August. Wildfires in Wyoming are triggered by a dry climate, drought, grasses die and dry out, and times when dry thunderstorms are more common. [1] Humidity levels, dryness of fuel, wind, and temperature also play a crucial role. Forests that have not had wildfires in recent years have more fire fuel, and trees killed by disease and insect infestation quickly dry up and become a prime fuel for wildfires. [2]

Summary

In mid-August, lightning sparked almost twenty wildfires in the Bighorn Basin, [3] including the Red Canyon, Spring Creek, and Sleeper Ranch fires. The Red Canyon Fire has prompted evacuations east of the Wind River Canyon, though no evacuations have been issued from the other fires. [4] [5] Western Wyoming was under a red flag warning, due to very dry and windy conditions, but the fires are not spreading towards highways or towns. [6] While the fires are driven by the dry and windy conditions, they are fueled by the invasive weed, cheatgrass. The area east of Thermopolis on the side of U.S. Route 20 is covered in cheatgrass, which is fueling the Red Canyon Fire and is damaging the native plants. [7]

Notes

  1. ↑ Containment means that fire crews have established and secured control lines around the fire's perimeter. These lines are barriers, like trenches or cleared vegetation, designed to stop the fire's spread. Containment reflects progress in managing the fire but does not necessarily mean the fire is under control or out. [8]
