A(n) Air Quality Action Day has been declared for Susquehanna Valley, PA, on Tuesday, Aug 31

Tomorrow’s Forecast
Tuesday, Aug 31: 112 AQI Unhealthy for Sensitive Groups Ozone
86 AQI Moderate Particle Pollution (2.5 microns)

Extended Forecast
Wednesday, Sep 1: 100 AQI Moderate Ozone
92 AQI Moderate Particle Pollution (2.5 microns)
Current Conditions: A strong area of high pressure is stuck over the region, and this will continue to be the case into the latter part of this week. Light winds in the boundary layer coupled with full sun and temperatures into the lower 90s have resulted in code ORANGE levels of ozone this afternoon. Fine particulate remains in the moderate range, due partly to the dryness of the air. Tonight will bring a mostly clear sky with a nearly calm wind. Lows will drop into the middle 60s. *** Tuesday’s forecast: For the day Tuesday, we will have another full dose of sunshine and temperatures perhaps in the lower and middle 90s in the afternoon. This will cause ozone levels to leap into the code ORANGE range once again, thus an action day is being declared. Fine particulate will rise well into the moderate range. *** Extended forecast: With high pressure slow to move anywhere this week, the potential for poor air quality will continue into at least Thursday. Code ORANGE ozone levels are possible each of these two days as well, and if humidity can rise a little more, fine particulate may also get to code ORANGE levels. A cold front then will pass through sometime during the day Friday. At this point, not much moisture exists with this front to bring any significant rainfall. We will also be watching Hurricane Earl as it moves close to the east coast late this week. Most likely it will remain off the coast as it moves to the north. Behind the front, things turn much cooler over the Labor Day weekend with sunshine most of the time, temperatures back down into the middle 70s, and a return to good air quality. —McAuliffe

Here are some Air Quality Action Day tips you can follow to help reduce pollution:

Days when ozone levels are expected to be high:

* Conserve electricity and set your air conditioner at a higher temperature.
* Choose a cleaner commute—share a ride to work or use public transportation. Bicycle or walk to errands when possible.
* Refuel cars and trucks after dusk.
* Combine errands and reduce trips.
* Limit engine idling.
* Use household, workshop, and garden chemicals in ways that keep evaporation to a minimum, or try to delay using them when poor air quality is forecast.
