Areas close to fires could see air quality levels reach unhealthy or hazardous status while the remainder of the area will likely see moderate to unhealthy air quality as effects from wildfire smoke get worse as well.
The "AirNow" map, https://www.airnow.gov/index.cfm?action=topics.smoke_wildfires (above), captured at 6 p.m. Monday, September 4, is so opaque you can't even see the underlying map of North Idaho. It shows a black triangle in Newport, indicating hazardous air quality at the gauging station there.
It also shows that the smoke stretches from the Atlantic to the Pacific and from south Texas clear into Canada.
Children, the elderly, and individuals with respiratory illnesses are most at risk of serious health effects. If you experience respiratory distress, you should speak with your physician.
