The Puget Sound area has been inundated by smoke from wildfires in the British Columbia interior over the last 3 days. During this time, air quality reported from the Loomis Trail Road air monitoring station showed air quality eventually degrading into the ‘Unhealthy for Sensitive Groups’ range.
Earlier today, it was reported air quality had improved overnight from ‘Unhealthy for Sensitive Groups’ range to ‘Moderate.’ The improvement has since continued to the point where, by this afternoon, the air monitoring station was reporting air quality in the ‘Good’ range.
But other locations are not faring as well and the National Weather Service (NWS) advised today that they are extending an air quality alert for western Washington through noon Monday. “Air quality may vary between moderate and unhealthy, though a few areas might see periods of good air,” NWS advised in their announcement.
