A Code Orange air quality action day has been declared for the Susquehanna Valley, the state Department of Environmental Protection announced Sunday.

High concentrations of fine particulates are expected on Monday. The increase in particle pollution could be unhealthy for sensitive groups, according to a news release.

"Code orange" concentrations of fine particle pollutant usually come along with  unseasonably warm temperatures. The highest concentrations will most likely be present in Lancaster County in the morning, the release states.

York County is expected to have fog Monday morning, followed by a sunny day with a high of 76, according to AccuWeather.

The air quality is expected to improve by Tuesday.

Residents within the code orange air quality action day area are encouraged to help reduce air pollution by:

  • Conserving electricity by setting air conditioning to a higher temperature;
  • Combining errands to reduce vehicle trips;
  • Limiting engine idling; and
  • Refueling cars and trucks after dusk.
