On December 30, 2021, a combination of long-term drought and hurricane-force winds set the stage for what would become the most destructive fire in Colorado history in terms of property loss. Driven by ferocious winds, a grass fire quickly advanced from the outskirts of Boulder on the neighboring cities of Louisville and Superior. Horrified residents had little time to evacuate as the wildland fire transformed into an urban firestorm. This story recounts the events of that day from the perspective of NOAA's National Weather Service meteorologists who sent the first high-wind warnings in the hours before dawn, and continued to alert residents throughout the day as the worst-case scenario unfolded.
