Smoke levels and wind directions are monitored by Nebraska and other states to predict when impacts to the air quality may occur. Information regarding prescribed burning impacts is available from the Nebraska Department of Water, Energy, and Environment (DWEE) at https://dee.nebraska.gov/smoke-and-air-quality. Alerts are based on data available from weather forecasts, smoke plume modeling, satellite imagery, and from air quality monitors located in Omaha, Bellevue, Blair, Lincoln, Beatrice, Grand Island, and Scottsbluff. Advisories for smoke and air quality are issued for affected areas by the Nebraska Department of Health and Human Services (DHHS) and Department of Water, Energy, and Environment (DWEE) and posted on agency webpages and social media sites. By notifying the media and local health departments, alerts help citizens protect their health by informing them of days where outdoor activities should be reduced or avoided to minimize exposure to smoke.
