The Pennsylvania Department of Environmental Protection and its regional air quality partnerships have forecast a Code Orange Air Quality Action Day for ozone on Monday, August 6th for the Philadelphia region, which includes Montgomery County.

The forecast states:

Stagnant conditions early in the day with a light southwesterly wind in the afternoon under mostly sunny skies will lead ozone concentrations to climb into the Code Orange range.

Increasing chances for showers and thunderstorms Tuesday afternoon are expected to limit ozone concentrations to the moderate range. Therefore, the Code Orange Air Quality Action Day is currently only expected for Monday.

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.
