A Code Orange Air Quality Alert will be in effect Tuesday for Washington, Allegheny, Butler, Beaver, Armstrong, Westmoreland and Fayette counties. This means that there is unhealthy air quality for people with asthma, lung disease, heart disease, young children, and older adults. If you are in this group, you may want to limit your time outside. The humidity will increase overnight, and the heat turns up Tuesday. You are urged to make sure to find a way to stay cool – with highs expected to be in the low to mid-90’s.
