Even if you don’t currently see smoke or flames, it is difficult to predict the condition of air quality related to the current Boulder County fires. High winds today will push smoke around.
In general, if you can see OR smell smoke, it is recommended that you avoid outdoor physical activities. If visibility is decreased in your neighborhood to less than five miles, smoke has reached levels that are unhealthy.
