Denver, Colorado – Outdoor sparks could ignite fast-moving grass fires across the Front Range within hours Thursday as powerful winds and extremely dry air push wildfire danger to critical levels.
According to the National Weather Service in Denver and Boulder, a Red Flag Warning is in effect from 11 a.m. through 9 p.m. Thursday for the I-25 corridor and much of northeast Colorado, including Denver, Greeley, Fort Morgan, Sterling, and Akron. Forecasters expect strong winds of 40 to 60 mph across the plains, with gusts potentially reaching 70 to 80 mph near the foothills.
Relative humidity may drop as low as 13 percent during the afternoon, creating conditions where even a small spark could spread rapidly through dry grasses. The highest risk areas include the plains of northeast Colorado and the Palmer Divide, where strong winds and low moisture levels often accelerate fire growth.
Officials warn residents to avoid outdoor burning, postpone yard work that could generate sparks, and follow all local fire restrictions during the warning period. Drivers along Interstate 25 and nearby highways may also encounter strong crosswinds during the afternoon commute.
Fire weather concerns may continue into Friday and Saturday as dry conditions persist across eastern Colorado. Additional fire weather alerts could be issued if wind and humidity thresholds remain elevated.
