Stagnant air advisory issued

November 18, 2022

The National Weather Service, Spokane, has issued an air stagnation advisory for North Idaho and northeastern Washington, in effect until 3 p.m. Monday, November 21. Light winds and little vertical mixing is expected to resu4lt in stagnant air that could cause issues for those with rerspiratory problems. Cold and very dry air over the region will promote strong overnight inversions with poor mixing each afternoon.

Concentrations of pollutants near the surface are expected to increase over time with the potential for degrading air quality. A weak weather system on Monday will bring increasing clouds with better ventilation and light precipitation is expected Tuesday.

People with respiratory illness should follow their physician's advice for dealing with high levels of air pollution during periods of stagnant air.

State air quality agencies highly recommend that no outdoor burning occur and that residential wood burning devices be limited as much as possible. According to state air quality agencies, prolonged periods of stagnant air can hold pollutants close to the ground where people live and breathe.

As of 11 a.m., Air qauality in Boundary and Bonner Counties is rated moderate and there are no burn bans in effect.
