OGDEN -- Wildfires in southwestern Idaho are causing crummy air along the Wasatch Front.
There are about seven fires burning in the Gem State, with the smoke affecting Utah's air quality, Department of Environmental Quality Public Information Officer Donna Spangler said.
The DEQ issued yellow air warnings from Box Elder to Salt Lake counties so far in response to the smoke.
"We haven't approached an unhealthy level yet," Spangler said, "but we are getting to that point if we don't have a weather pattern that will change."
So far, the National Weather Service does not forecast any changes in the Top of Utah's climate through Saturday.
However, NWS forecaster Nanette Hosenfeld said a good afternoon wind could cause the dirty surface air to rise out and mix with the cleaner air above it. If it does not happen this afternoon, Hosenfeld said, it could happen Wednesday.
In the mean time, during yellow air alerts, sensitive groups including people with lung disease, such as asthma, children and older adults should reduce prolonged or heavy outdoor exertion, the department said.
Normally summer air pollution is caused by ozone levels from vehicle emissions, hot air and sunlight.
"You have a certain weather pattern where it's stagnant," Spangler said, "it kind of hangs over you."
The DEQ asks drivers to be mindful and reduce their driving whenever possible.
"Just driving in this condition is making it worse," Spangler said.
