COLORADO SMOKE OUTLOOK:
Monday, August 21, 2017, 2:30 PM MDT
Smoke from wildfires in the northwest United States and western Canada is being transported into Colorado. The influence of this smoke is expected to produce areas of haze, particularly in northern Colorado, however these conditions are possible throughout the state. Significant health impacts are not anticipated, however, unusually sensitive people should consider reducing prolonged or heavy exertion on Monday and Tuesday.
Light to moderate smoke is also possible near prescribed fires and small wildfires around the state.
Unfortunately, the Fort Collins PM monitor does not appear to have any data available since Saturday morning, so I cannot tell you what the impact is on surface air quality here in Fort Collins. The Greeley monitor does show PM concentrations that were elevated (especially overnight), but there's been lots of variability, so it's difficult to tell if wildfire smoke is the culprit.
