DOVER, Del. (AP) - Delaware officials are issuing a "Code Orange" air quality warning.
The Department of Natural Resources and Environmental Control says ozone concentrations on Wednesday are expected to be unhealthful for sensitive people. Officials say outdoor activity should be limited for young children, the elderly, and those with heart or respiratory conditions.
Particulate concentrations are expected to rise, but remain in the moderate range.
Officials say they expect a period of poor air quality over the next several days as a heat wave affects the state.
