The Pennsylvania Department of Environmental Protection (DEP) and its regional air quality partnerships have forecast a Code Orange Air Quality Action Day for ozone Friday in Cumberland County.
DEP says strong and building ridge of high pressure will promote mostly sunny skies Friday and temperatures in the upper 80s. The high temperatures and sunshine in conjunction with light surface winds will act to promote ozone development into the code Orangerange during the afternoon hours.
On Air Quality Action Days, young children, the elderly and those with respiratory problems, such as asthma, emphysema and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities.
The U.S. Environmental Protection Agency’s standardized air quality index uses colors to report daily air quality. Green signifies good; yellow means moderate; orange represents unhealthy pollution levels for sensitive people; and red warns of unhealthy pollution levels for all.
