PA DEP has declared Air Quality Action Day on Nov. 9

A(n) Air Quality Action Day has been declared for Susquehanna Valley, PA, on Monday, Nov 9
Tomorrow’s Forecast
Monday, Nov 9: 120 AQI Unhealthy for Sensitive Groups Particle Pollution (2.5 microns)

Extended Forecast
Tuesday, Nov 10: 65 AQI Moderate Particle Pollution (2.5 microns)
Current conditions:**An Air Quality Action Day will be declared for the day Monday** Fine particulate concentrations are elevated in the code ORANGE range across most of the area this Sunday afternoon, and these levels will continue into the day Monday as a stagnant weather pattern continues. *** Monday’s forecast: A strong temperature inversion in tandem with weak low and mid level winds will allow for PM2.5 buildups during the day Monday. Code ORANGE concentrations of this pollutant are likely with mostly sunny skies and unseasonably warm temperatures. The highest concentrations will likely be across Lancaster County during the morning hours. *** Extended forecast: Air quality will improve Tuesday as a strong upper level ridge starts to break down and allows for an increase in low level winds, mixing, and dispersion. Nonetheless, moderate air quality is still likely. Further improvements to the good range will occur by Wednesday as a cold front approaches and brings an opportunity for some needed rainfall. Cooler air will follow this front late this week, with temperatures moving down closer to November normals.—McAuliffe
Days when particle pollution levels are expected to be high:

* Reduce or eliminate fireplace and wood stove use.
* Avoid using gas-powered lawn and garden equipment.
* Avoid burning leaves, trash and other materials.

This forecast is brought to you by the Pennsylvania Department of Environmental Protection (PA DEP).

DEP Issues a Code Orange Air Quality Action Day Forecast for June 9, 2020

Harrisburg, PA – The Pennsylvania Department of Environmental Protection (DEP) and its regional air quality partnerships have forecast a Code Orange Air Quality Action Day for ozone on June 9, 2020, for southeastern and southcentral Pennsylvania (encompassing the counties of Bucks, Chester, Cumberland, Dauphin, Delaware, Lancaster, Lebanon, Montgomery, Philadelphia, and York).
Strong sunshine, temperatures close to 90 degrees Fahrenheit, and light south to southwest winds will act to bring ozone concentrations to code ORANGE levels Tuesday afternoon. Concentrations of ozone are expected to be lower on Wednesday with only partly sunny skies and the chance for shower and thunderstorm development.
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.  Read more
