The Rhode Island Department of Environmental Management is predicting that air quality will reach unhealthy levels in Rhode Island. . . A very hot and very humid air mass with west winds will be present at that time, which will lead to unhealthy air conditions. The poor air quality will be due to elevated ground level ozone concentrations. Ozone is a major component of smog and is formed by the photochemical reaction of pollutants emitted by motor vehicles, industry and other sources in the presence of elevated temperatures and sunlight.
