Prepared by: Carolyn Kelly, Air Resource Advisor Trainee (ckelly8384@gmail.com)
Andrea Holland, Air Resource Advisor (andreahollandsears@gmail.com)
Note:
The Manson monitoring site has been inoperative for the last week caused by a
malfunction in the instrument. Please
refer to information provided from the Chelan monitor for estimating impacts
to Manson.
Sunday:
Greater fire activity is expected
today. While late morning will see
some lifting of smoke in impacted areas, more smoke is expected to settle
into nearby communities. Those closest to the fires such as Chelan, Manson, Twisp,
Winthrop and Omak will see air quality reach into very unhealthy levels by
the evening and throughout the night. Omak
may see periods of hazardous air quality.
Monday: Chelan
and Manson are not likely to see much relief from smoke today. Winthrop and
Twisp may see some relief in the morning with a return to unhealthy air
levels by the afternoon as fire activity picks up. Omak will continue to see unhealthy levels
of smoke with periods ranging between very unhealthy to hazardous.
Tuesday: Leavenworth and Wenatchee should see some relief
from the smoke. Smoke will remain persistent for Chelan, Winthrop, Twisp and
Omak areas
