Monday, August 24, 2015 - Here's why SCALE is important...
In the image below, concentrations at Hayfork can be seen peaking at 10 am. If scale is not considered, it may look as though air quality was pretty bad in Hayfork this morning, then improved throughout the afternoon.
Put into context of over one week, however, this is what the concentration graph looks like:
Note: Concentrations in the above graphs are displayed in milligrams per cubic meter averaged over one hour.
Always check the scale!
Monday, August 24, 2015 - North Coast Unified AQMD Smoke PSA & Unhealthy Advisory

Monday, August 24, 2015 - Rough Fire Air Quality Report
Air Quality Report Issue
Date: 08/24/2015
Rough Fire – Sierra
National Forest Prepared by:
Ariane Sarzotti and Jamie Tripp

Forecast conditions represent impacts
from smoke from the Rough Fire.

|
Fire: On the southern zone, Fire continues
to spread towards the Windy Gulch area which includes Lockwood Grove and
Evans Grove. A critical line is near completion from Hwy 180 to the
Kings River. On the northern zone of
the fire, blacklining was conducted to fortify the line from
Bailey Bridge to Balch Camp on Balch Camp Rd. Hand and aerial firing is anticipated
to continue over the next several days to keep the fire backing to the
north fork of the King’s River. The fire is now 49,440 acres and 17%
contained.
Air Quality
Today: With slight changes in weather patterns,
we will see heavy concentrations of smoke in the western foothills and areas
within the Kings River Canyon until mid-afternoon. Owens Valley will see air quality degrading
as smoke is lifted and transported to the northeast late afternoon to
midnight. This evening smoke will once
again settle into the Kings River Valley, bringing smoke into the western
foothills and the San Joaquin Valley overnight.
Air Quality Tomorrow: A similar pattern to today is expected.

Monday Aug.24, 2015 - Shasta-Trininty/Six Rivers Smoke/Air Quality Report
Monday
August 24, 2015
Shasta-Trinity
& Six Rivers Complexes Mike Broughton and Greg Hosburg
Forecast conditions represent impacts from smoke. Contributions from ozone and other pollutants
are not reflected.
|
Smoke Synopsis: 0945 AM Final
|
||||
|
With the exception of a few hours here and there,
smoke generally cleared out of many of the deep Trinity Valley locations on
Sunday. A general transport flow from
the south combined with a coastal onshore push from the west will send smoke
up into Siskiyou County and southern Oregon, but slightly more unstable
conditions today and Tuesday may allow for clearing conditions during the
afternoon. Coastal areas will
experience the typical effects of a deep marine layer.
The most active fires include the Lassic Fire
(Mad River Complex), the Denny and French Creek areas of the River Complex, and
the Pattison Fire (South Complex).
