Ozone Alert Center

When an Ozone Alert is issued via the SkyCast, an unhealthy concentration of ozone pollution is predicted for the following day.

The SkyCast is the ozone forecast for the Greater Kansas City region. Like a weather forecast, it tells you what air quality conditions are most likely to be for the next day. The SkyCast is issued each afternoon by 4 p.m. between April 1 and October 31, when we are most likely to experience an Ozone Alert.

What do the SkyCast colors mean?

The SkyCast uses colors based upon the EPA’s Air Quality Index (AQI) to let you know:

  • When to take steps to protect your family’s health.
  • Ozone Alert day actions to help return ozone concentrations to acceptable levels.

Protect your health and reduce pollution

When an Ozone Alert is issued, cut back on or reschedule strenuous outside activities. Stay indoors in a well-ventilated or air-conditioned building. If you must be active outdoors, try to schedule activity before 10 a.m. or after 7 p.m.

Drive less. Combine errands and put off less-necessary trips for a cooler day, carpool, or use public transit. Better yet, take a leisurely walk or bike ride, preferably early in the morning or later in the evening.

Avoid fueling. Simply filling your vehicle with gasoline can lead to pollution as fumes escape and tiny drips and spills occur, and gas vapors react with heat and sunlight to form ozone. If you must fill your tank, do so after dusk. And be sure to avoid “topping off” your tank.

Postpone mowing. Lawn and garden equipment is responsible for an estimated 9 percent of the Kansas City area’s ozone-forming emissions. Postpone yard work that involves power equipment until the Ozone Alert is over.
