The highest AQ index in Washington (as of 16:00 PDT) is currently the Clarkston area. Particle Pollution (PM2.5) is measuring at 54 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Particle Pollution (PM2.5) will be in the Bremerton-Silverdale-Bainbridge Island area. It is forecasted to be Good, meaning air quality is satisfactory, and air pollution poses little or no risk.
For Mar 26-30 (Thu-Mon): We'll have mostly GOOD air quality for the rest of this week and weekend. Some sun should return on Thursday and continue through late Saturday, so evenings may see some spikes into MODERATE in areas with a lot of woodburning. Sunday will see more clouds and a chance of rain.
