Fire spread was exacerbated by gusting winds reaching over 100 mph, the NWS reported.
The Boulder Office of Emergency Management said residents should “leave immediately” if they see fire in their area.
Footage released by the NWS Boulder shows winds blowing as a plume of smoke is seen in the distance. “Fast-moving grass fire south of Boulder visible from our office,” they wrote in a tweet. “Multiple wildfires burning across the county.”
“This is becoming a very high impact wind event for our area,” they warned. “Please take it seriously and abide by any evacuation orders from local authorities.” Credit: National Weather Service Boulder via Storyful
