       Area                          PSI Forecast for Tomorrow

    MODERATE IN THE:
      Coastal Area                            AQI:  57  Ozone
      Metropolitan Area                       AQI:  87  Ozone
      Inland Orange County                    AQI:  87  Ozone
      Temecula/Anza Area                      AQI:  67  Ozone
      San Gabriel Mountains                   AQI:  74  Ozone
      Big Bear Lake                           AQI:  57  Ozone
      Banning Pass Area                       AQI:  97  Ozone
      Coachella Valley/Low Desert             AQI:  77  Ozone
      Antelope Valley                         AQI:  65  Ozone
      Victor Valley                           AQI:  77  Ozone
      Northern Mojave Desert                  AQI:  58  Ozone
      Central Mojave Desert                   AQI:  62  Ozone
    UNHEALTHFUL FOR SENSITIVE GROUPS:
      San Fernando/Santa Clarita Valleys      AQI: 114  Ozone
      San Gabriel                             AQI: 116  Ozone
      Riverside Valley                        AQI: 145  Ozone
      San Bernardino Valley                   AQI: 137  Ozone
      Hemet/Elsinore Area                     AQI: 114  Ozone
      San Bernardino Mountains                AQI: 142  Ozone

    The AQI measures the amount of pollutants in the air, whether ozone, carbon monoxide, nitrogen dioxide or PM10 (particulate matter).
      
    Conditions are considered ``good'' when AQI levels are between zero and 50. No health impacts are expected when air quality is in this range.
      
    When AQI levels are 51 to 100, air quality is deemed ``moderate,'' which means that unusually sensitive people should consider limiting prolonged outdoor exertion.
      
    Air quality is designated ``unhealthful for sensitive groups'' when AQI levels are from 101 to 150. At this level, active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
      
    When AQI levels are between 151 and 200, air quality is deemed ``unhealthful.'' At this level, active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion. Everyone else, especially children, should limit prolonged outdoor exertion.
      
    ``Very unhealthful'' air quality is declared when the AQI registers between 201 and 300. Active children and adults, and people with respiratory disease,should avoid all outdoor exertion when the AQI is at this level. Everyone else, especially children, should limit outdoor exertion.
