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.

Forecast Discussion: Updated Friday, April 28, 2017, 10 a.m. ** PM10 HEALTH WATCH IN EFFECT FRIDAY, APRIL 28TH ** ** OZONE HEALTH WATCH IN EFFECT SUNDAY APRIL 30TH & MONDAY, MAY 1ST ** A developing low pressure system will impact the area today. As it moves towards the four corners area it will strengthen and create a rather strong pressure gradient which will bring gusty winds. The wind gusts are expected to approach and perhaps exceed 40 mph! The strong gusts will help create areas of blowing dust with the PM10 levels today expected to approach and perhaps exceed the health standard. As a precaution the issued PM10 Health Watch for today remains in effect. Anyone with respiratory and/or heart ailments should limit outdoor activities during periods of blowing dust. The upper level low pressure system will eventually move eastward on Saturday but not before bringing another breezy day to the area. Lighter winds and favorable early morning wind directions for elevated PM10 at Hidden Valley will bring elevated PM10 on Sunday and Monday. The PM2.5 levels will be elevated today due to the aforementioned blowing dust before dropping a bit on Saturday only to be elevated on Sunday and Monday due to morning temperature inversions and local dust causing activities. The ozone levels will be solidly in the moderate category with northern areas perhaps approaching the health standard, thus have issued an ozone health watch for both Sunday and Monday. Anyone can help lower polluting activities by combining trips, limit automobile idling and use of drive-thrus and refueling after dark. Forecaster: S. DiBiase
