The Department of Environmental Protection and the Southwest Air Quality Partnership have forecast Tuesday, September 26 will be a Code Orange Air Quality Action for ozone in the the Pittsburgh Region-- Allegheny, Westmoreland, Beaver, Butler, Armstrong and Fayette counties and the Liberty-Clairton Areas.
These forecasts are provided in conjunction with the Southwest Air Quality Partnership.
On Tuesday, a strong ridge of high pressure with light winds, sunshine, and unseasonably warm air in the middle to upper 80s will bring ozone concentrations to the code ORANGE level. A cold front on Wednesday will bring ozone concentrations down to the low moderate range. Marked improvements in air quality are expected starting on Thursday.
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.
To help keep the air healthy, residents and business are encouraged to voluntarily restrict certain pollution-producing activities by:
-- Refueling cars and trucks after dusk
-- Setting air conditioner thermostats to a higher temperature
-- Carpooling or using public transportation; and
-- Combining errands to reduce trips.
