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
Friday, an approaching upper-level low pressure system will produce moderate onshore winds during the afternoon and evening hours. While these winds will aid in dispersion, pollutant carryover from the morning will lead to high-Good particle levels. Saturday, an upper-level low pressure system passing through northern California will produce moderate onshore winds. These winds will disperse pollutants, leading to Good particle levels. Sunday, surface high pressure over the Pacific Northwest will generate moderate and gusty northwesterly winds, which will keep the atmosphere mixed. Therefore, particle levels will remain Good.
