Temperatures across southwestern Pennsylvania are expected to creep toward 90 this afternoon with a chance of thunderstorms, and pollutants in the air are reaching unhealthy levels.
The state Department of Environmental Protection has issued a code orange air quality alert for an area that encompasses Allegheny, Armstrong, Beaver, Butler, Fayette, Washington and Westmoreland counties.
A code orange air quality alert means that pollution concentrations may become unhealthy for those in sensitive groups, such as children, the elderly and people suffering from asthma, heart disease or other lung afflictions.
Avoiding strenuous activity or exercise outdoors can minimize the effects of air pollution.
