Air Quality Health Advisories

THERE ARE CURRENTLY NO AIR QUALITY ADVISORIES IN EFFECT.

Here is some general information that may be helpful.

The following is an easy way for the general public to approximate risk with a visibility assessment:

Categories Visibility in Miles
Good 11 miles and up
Moderate 6 to 10
Unhealthy for Sensitive Groups 3 to 5
Unhealthy 1 ½ to 2 ¾
Very Unhealthy 1 to 1 ¼
Hazardous Less than 1 mile

When using the visibility index to determine smoke concentrations, it is important to:

  • Face away from the sun.
  • Determine the limit of your visibility range by looking for targets at known distances (miles). The visible range is the point at which even high-contrast objects (e.g., a dark forested mountain viewed against the sky at noon) totally disappear.
