SPOKANE, Wash. — The smoke that is filling the skies is coming from wildfires across Oregon, Canada, Idaho, Montana and Washington.
Air quality in the Spokane area is considered "Hazardous”. It is being caused by winds blowing wildfire smoke in our area. There are South westerly and westerly winds from South Oregon up into Washington. The smoke is being brought from upper levels of the atmosphere.
There seemed to be a drastic increase in the amounts of smoke as Monday transitioned to Tuesday. What made it worse were lower level winds, the gusts we feel down on the ground. These winds propelled mass quanitities of smoke into areas across the Inland Northwest.
A combination of the fires and smoke creates the “Hazardous” air for the Spokane area. At this category, the entire population is likely to be affected.
