Easy Ways to Improve Air Quality
Air pollution poses a health risk to everyone. Your risk depends on your age, current health status and the length of exposure to the pollution. Some people are more vulnerable, especially children, pregnant women, the elderly, and those with lung or heart disease.

Here are five ways to reduce pollution:

  1. Cut back on driving
  2. Never use charcoal lighter fluid
  3. Don't idle - turn off your engine when parked
  4. Use electric-powered tools
  5. Refuel after the sun goes down

A Spare The Air alert in the Sacramento region will be issued when the AQI for ground-level ozone pollution is forecast to reach 126 or above.

Air Quality Forecast and Weather Discussion
Tuesday and Wednesday, an upper-level ridge of high pressure will build over northern California, reducing mixing and producing sunny skies and warmer temperatures. These conditions will enhance ground-level ozone formation. In addition, light northwesterly winds will limit pollutant dispersion. As a result, ozone levels will be Unhealthy for Sensitive Groups on both days. Thursday, mostly sunny skies and temperatures in the low- to mid-90s will continue to support ozone formation, and light onshore winds will reduce pollutant dispersion. As a result, ozone levels will continue to be Unhealthy for Sensitive Groups.
