Smoke Synopsis (prepared by Andrea
Holland, Air Resource Advisor)
|
Yesterday’s higher humidities and cooler temperatures coupled with
moderately strong winds reduced smoke concentrations in most communities
around the Bridge99, Logging Unit Complex and Shaniko
Butte fires. Monitors indicate that
yesterday’s air quality was moderate for particulate matter in Madras and
Prineville. Bend and Sisters continued
to experience good air quality.
Today’s light winds will hinder smoke from clearing in
communities downwind (east) of the Logging Unit Complex and Shaniko Butte fires.
Air quality in Madras and Warm Springs is likely to remain moderate
until late afternoon when winds pick up.
Tuesday’s forecast indicates stronger winds associated with
storm front. Morning winds will drive
any smoke towards the northeast. Winds
will shift drift smoke to an easterly direction in the mid-afternoon. Air quality will likely remain in the
moderate range for Madras and Warm Springs.
Sisters, Prineville, Bend and
Redmond should see continued good air quality.
Wednesday will see wind from a west to northwest
direction. Depending on the level of
fire activity in the Logging Unit Complex smoke will impact Madras and Warm
Springs.
