The Shelby County Health Department has issued a Code Orange Ozone
Health Advisory effective for Shelby County Tennessee, Crittenden
County Arkansas, and DeSoto County Mississippi, including the city 
of Memphis that will remain in effect until sunset today. This ozone 
health advisory is due to monitored ozone values that are unhealthy 
for sensitive groups. These values have exceeded the Environmental 
Protection Agency's federal safe health standard. The Shelby County 
Health Department recommends that sensitive groups which include 
active children and adults, and people with respiratory disease, 
such as asthma, limit prolonged outdoor exertion. Please continue to 
check the latest air quality forecasts and updates until monitored 
values return to safe levels. For more information go to
