Forecast Discussion: Areas of smoke are expected through the day and evening. Certain areas may experience hours of high particulate matter levels and persist into the “Unhealthy for Sensitive Groups " category.

NOTE: Most areas of the state do not have air quality monitors, so people are encouraged to be cautious if visibility is affected due to smoke and particulates from wildfires. If visibility is reduced to less than five miles, sensitive groups should limit activity. If visibility is reduced to less than three miles, air quality is considered unhealthy and people should limit outdoor exertion.

ALSO NOTE: Air quality is likely to change drastically with slight changes in fire behavior and weather conditions. The Air Quality forecast for tomorrow is in the “Moderate" category.
