The highest AQ index in Washington (as of 17:00 PST) is currently the Maple Falls area. Particle Pollution (PM2.5) is measuring at 160 (Unhealthy). This means some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects.
Over the next few days, the highest Particle Pollution (PM2.5) will be in the Darrington area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
For Tues-Fri (Jan 21-24): MODERATE air quality continues, especially in high wood smoke areas, due to dry air, cold temps, and low winds. We expect this to continue this week, but if levels of smoke are UNHEALTHY FOR SENSITIVE GROUPS, we could issue a burn ban. We'll update this forecast as conditions change.
