...AIR QUALITY ALERT IN EFFECT FROM 10 AM THIS MORNING TO 8 PM EDT
THIS EVENING...
THE SOUTH CAROLINA DEPARTMENT OF ENVIRONMENTAL SERVICES (SCDES) HAS
ISSUED A CODE ORANGE GROUND LEVEL OZONE ACTION DAY FOR THE CATAWBA
REGION OF SOUTH CAROLINA, FROM 10 AM THIS MORNING TO 8 PM EDT THIS
EVENING.
DOMINANT HIGH PRESSURE WILL ENSURE MINIMAL CLOUD COVER AND LIGHT AND
VARIABLE WINDS. LONG-RANGE WILDFIRE SMOKE WILL ALSO TRANSPORT OZONE
PRECURSORS INTO THE AREA. THESE FACTORS WILL ALLOW FOR SUFFICIENT
OZONE PRODUCTION, COMPOUNDING WITH WEAK DISPERSION CHARACTERISTICS
OF AN ALREADY POLLUTANT-LOADED ATMOSPHERE.
AN OZONE ACTION DAY MEANS THAT ATMOSPHERIC CONDITIONS WILL LIKELY
PRODUCE UNHEALTHY CONCENTRATIONS OF GROUND LEVEL OZONE AIR POLLUTION.
A CODE ORANGE FORECAST INDICATES THAT GROUND LEVEL OZONE
CONCENTRATIONS ARE EXPECTED TO BE UNHEALTHY FOR SENSITIVE GROUPS,
WHICH INCLUDES PEOPLE WITH LUNG DISEASE, OLDER ADULTS, AND CHILDREN.
SENSITIVE GROUPS SHOULD REDUCE PROLONGED OR HEAVY OUTDOOR EXERTION,
TAKE MORE BREAKS, AND DO LESS INTENSE ACTIVITIES, ESPECIALLY DURING
AFTERNOON AND EARLY EVENING HOURS. YOU CAN HELP PREVENT OZONE
POLLUTION BY WALKING OR RIDING YOUR BICYCLE, TAKING YOUR LUNCH TO
WORK, REDUCING IDLING, CONSERVING ENERGY, AND KEEPING YOUR VEHICLE
PROPERLY TUNED. FOR ADDITIONAL INFORMATION, PLEASE VISIT THE SOUTH
CAROLINA DEPARTMENT OF ENVIRONMENTAL SERVICES WEBSITE AT
