Smoke from Prescribed burning in the central plains may affect the
air quality in Nebraska.  Smoke levels and wind directions are
monitored by Nebraska and other states to predict when impacts to
the air quality may occur.

Information regarding wildfires and Impacts in Nebraska is
available from the Nebraska Department of Environment and Energy
(NDEE) at https://dee.nebraska.gov/air/smoke-awareness-nebraska.

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 Environment and Energy (NDEE) 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.
