A big wind blew in plenty of smoke Sunday afternoon, mostly from the Shadow Lake Fire back burning procedures. Frank Messina with the Department of Environmental Quality says, now that we have an inversion layer, we could have the smoke with us for several days. "During the day, it does change to a certain degree. But what the problem is, is it's like a kettle with a seal on top; it just compounds itself and just holds it in. And unless we get good mixing, it just doesn't change. And for the next few days we're probably going to be living in a very smoky environment in the Central Oregon area." Messina says we are in the "moderate" area right now. If you are someone with asthma or some kind on compromised breathing problem, it's best to stay indoors.
