Sources: SPC fire weather outlooks; active wildfires from the NIFC WFIGS current incident locations (wildfires not yet 100% contained or declared out); smoke from the NOAA Hazard Mapping System, where analysts outline smoke on GOES imagery several times a day (this shows smoke somewhere in the column, not necessarily at ground level); AQI from AirNow reporting areas (hourly, for the dominant pollutant). AirNow data are preliminary and not fully verified. For official AQI and health guidance, use AirNow.gov.
