Unhealthy air may accompany Friday's high temperatures

Friday’s high temperatures could also include a dose of unhealthy air.

The S.C. Department of Health & Environmental Control issued an air quality alert that will be in effect from 6 a.m. to 9 p.m. Friday, when ground level ozone levels in the region are expected to exceed health standards.

The alert includes Richmond, Columbia, Aiken and Barnwell counties.

Higher levels of ozone, a component of smog, can aggravate respiratory ailments. Active adults and children should also limit prolonged outdoor exertion, the advisory said.

Temperatures in the Augusta area are expected to reach 102 on Friday, with a forecasted high of 104 Saturday and Sunday — all with no rainfall expected.
