— Hot temperatures and stagnant air led air-quality officials to declare an ozone-action day for the Triangle and other metro areas across North Carolina on Monday.

The "Code Orange" is the first ozone alert issued for the Triangle this summer. The state Division of Air Quality also designated Tuesday a "Code Orange" day for the Triangle, the Triad and the Charlotte area.

A high-pressure system sitting over the Southeast was expected to produce high temperatures in the upper 90s on Monday. Low humidity would prevent a heat index over 100, according to WRAL Meteorologist Elizabeth Gardner.

People who are sensitive to air pollution should avoid moderate exertion outdoors in the afternoon, according to officials. Sensitive groups include children who are active outside, people who work or exercise outdoors and those with asthma, bronchitis, emphysema and other respiratory ailments.

Officials also asked area residents to carpool or drive less and to avoid using gas-powered lawn equipment until later in the evening.

A cold front is expected to cross North Carolina late Tuesday, bringing lower temperatures and an increased chance of rain on Tuesday evening and Wednesday, Gardner said.
