The highest AQ index in Idaho (as of 3:00 MST) is currently the Idaho City area. Particle Pollution (PM2.5) is measuring at 67 (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 Sandpoint 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.
Precipitation over night with wintry weather likely in higher elevations. Through the rest of the week clear and sunny with seasonal temperatures. Low wind speeds paired with low night-time temps may allow air of poor quality to be trapped in low lying areas. Air Quality should be mostly GOOD to MODERATE through the week.
