Ozone Alert Issued in Boulder, CO Due to Smoke From Fires…in Canada

Ozone Alert Issued for Boulder County, Front Range Due to Smoke From Canadian fires
The Colorado Department of Public Health and Environment and the Regional Air Quality Council have issued an ozone alert for Boulder County and other counties along the Front Range due to smoke from fires in Canada.
The alert says ozone concentrations are expected to reach the “unhealthy for sensitive groups” range this afternoon and evening, and warns that unusually sensitive people should consider reducing prolonged or heavy exertion.
The alert is in effect until at least 4 p.m. today.
According to the alert, smoke from fires in Canada is causing hazy skies across portions of Colorado.
I did a bit more digging and the smoke isn’t just from fires in Canada, it’s from fires in northern Canada, as in the Northwest Territories. Here’s a map:
