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.

Forecast Discussion: Ozone concentrations had risen well into the yellow criteria over the CSRA and the northern part of the state as of the mid-afternoon hours on Friday. Readings along the coast and into the Pee Dee were lower as the air mass had a cleaner, oceanic history. Saturday's readings are expected to be similar, with yellow criteria readings again expected over all of the state except for the Pee Dee and coast.
