The weather might have been cooler Wednesday in Oklahoma, but it also brought increased potentially dangerous air conditions in the northern part of the state.

The Department of Environmental Qualilty issued an air quality health advisory covering 29 counties stretching from Beaver in the Panhandle eastward to Bartlesville, Tulsa and Miami.

Air Quality Index health scale and suggested actions

The only clean air in the state was in six counties in the southeast.

What prompted the advisory? It might have been smoke from Canadian wildfires because the National Weather Service said Wednesday that hazy smoke from the fires reduced air quality in Kansas to “unhealthy.” The advisory in Kansas included Wichita in the southern part of the state.

“Northwest winds aloft are bringing down smoke from wildfires in Canada and the Pacific Northwest,” that office said on Twitter, reported the Topeka Capital Journal.
