BETHESDA, Md. —
An air quality alert is in effect across the Washington, D.C., and Baltimore areas, including Montgomery County, as smoke from Canadian wildfires drifts across the region, pushing pollution to levels considered unhealthy for everyone, according to the Metropolitan Washington Council of Governments and the Maryland Department of the Environment. As of Friday afternoon, the alert had reached Code Purple, meaning very unhealthy.
