AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Updated Friday, November 17, 2017 The Hidden Valley PM10 and PM2.5 levels on Thursday once again exceeded their respective health standards (33rd day in 2017 for PM10 and 11th for PM2.5). Today is also starting out on the elevated side of particulates at Hidden Valley. The initial PM10 AQI forecast of 85 (mid-range of the moderate AQI scale) has been revised into the Unhealthy for Sensitive Groups category due to the level of elevated PM10 early this morning and the likelihood of the PM10 health standard once again being exceeded at Hidden Valley. The weather this weekend will feature slightly cooler temperatures with mainly clear skies (some occasional high cloudiness). It’s a tough time of year for particulates due to local dust causing activities such as cotton harvesting and associated vehicle travel on unpaved roads. That said, the PM10 levels this weekend are forecasted to be in the good to mid-range of moderate on the AQI scale in most places with Hidden Valley forecasted to be in the upper range of the moderate AQI category. The PM2.5 forecasts for this weekend are in the good to mid-range of the moderate AQI category with ozone forecasted to remain in the good category. High pressure will build into the area again next week, however there’s a quick moving trough that is forecasted to skirt by the Four-Corners area early next week which may delay the high pressure’s influence on the local area. Early next week the elevated weekday dust causing activities along with the enhanced local dust activities in/around Hidden Valley are expected to influence the particulate levels (PM10 and PM2.5) and so have forecasted a PM10 exceedance and near PM2.5 exceedance (100 AQI) at Hidden Valley on Monday. Elsewhere the PM10 levels early next week are forecasted to be in the good to upper range of the moderate AQI category. Unfortunately at this point there still doesn’t appear to be any significant precipitation expected for the foreseeable future.
