WENATCHEE — Air monitoring stations around North Central Washington are breathing just as easy as you are.
With the end of a longstanding thermal inversion and the intermittent rainfall that began over the weekend, air monitors barely registered any particulate pollution this morning.
Smoke-troubled Cashmere showed fluctuations between zero and 2 micrograms of fine particles per cubic meter of air this morning — deep into the zero to 13.4 microgram range for “good” air. The reading was similar in Wenatchee and every other monitor site.
Cashmere hasn’t reached an unhealthy 24-hour average of fine pollutants — 35.5 micrograms — since Wednesday. The Chelan-Douglas Health District last issued a dirty-air warning on Friday, when air was rated moderate to unhealthy for sensitive groups.
The Washington Department of Ecology operates permanent air monitors in Wenatchee, Chelan, Omak and the Methow Valley. Some temporary U.S. Forest Service monitors, placed in Cashmere, Quincy, Pateros and Entiat as the smoke emergency worsened, may be removed later this week, according to federal ecologists.
