If you caught a whiff of campfire in parts of northeast Colorado on Friday and started eyeing your neighbor’s grill, you were in good company. A faint smoky smell and some light haze had folks from Greeley to the northern Front Range calling in reports of a possible fire. Crews checked it out but quickly realized the scent was riding in from the east, not coming from anything burning inside city limits.
According to 9News, National Weather Service forecasters and local fire departments traced the odor to wildfires burning in Nebraska. The Greeley Fire Department said it fielded many of the concerned calls but did not find any active fires within the city.
Where the smoke came from
Satellite-based smoke tracking shows plumes forming over central Nebraska and drifting toward the High Plains, lining up with the timing of the smoky smell in northeastern Colorado, according to NOAA. Those products identify numerous light-density smoke plumes over Kansas and central Nebraska that, under strong winds, can travel hundreds of miles.
Air-quality advisory and who is at risk
The Colorado Department of Public Health and Environment issued an Air Quality Health Advisory for much of eastern Colorado on Friday, specifically naming counties such as Larimer and Weld. The advisory explains that fine particles from wildfire smoke can worsen heart and lung disease and advises older adults, children, and people with respiratory conditions to cut back on outdoor exertion while smoke is in the area.
What to expect this weekend
A sharp cold front is forecast to roll across the Front Range from Saturday night into Sunday, bringing mountain snow squalls and a fast temperature drop for the Denver metro. Winds had already shifted Friday morning, helping pull the smoke westward. Forecasts called for gusts of about 30-40 mph in the Denver area, with much stronger gusts in the foothills, the kind of setup that can keep smoke suspended above the region or shove it into different neighborhoods, as reported by 9News and echoed in local outlooks. Expect the smoke pattern to shift as the winds and front evolve.
How to protect yourself
Health officials say people who are sensitive to smoke should stay indoors with windows closed, run a HEPA air purifier if they have one, and avoid strenuous outdoor activity while the advisory is in place. They recommend checking up-to-date local readings on AirNow and on the state advisory page before heading outside, and using an N95 mask for short trips outdoors if you need to go out.
Local fire and public health agencies plan to post updates as conditions change. Residents are urged to sign up for county alert systems and follow local fire departments for potential evacuation information, especially in rural areas. Officials also stress that people should lean on official advisories instead of unverified social media posts while the situation develops.
