State-Wide Smoke Report - Thursday August 27, 2015

Today, air quality will remain moderate to unhealthy across much of the State, from the southwest to the northeast, with good air quality occurring in the northwestern and southeastern portion of the State.  Figure 1 below illustrates the AQI readings as of 11:30 am across the State.  Note, Enterprise is experiencing the worst air quality as indicated by the red dot.  Refer to the air quality report for NE Oregon posted on this blog for more details of what to expect in this region.

Figure 1.  Oregon DEQ AQI at 11:30 am on Thursday August 27, 2015.

The Blue Sky smoke model is showing a similar pattern for the next two days across the state, as shown in Figures 2 and 3 below.  Note, however, that with the expected increase in relative humidity and cooler temperatures in the western portion of the region, fire activity is expected to diminish.   Because the Blue Sky modeling framework assumes today's and tomorrow's smoke production from the fires will be the same as yesterday, it cannot account for the expected change in fire behavior. Consequently, I believe the model is over-predicting what will occur for the southwest portion of the State on Friday.

Smoke Forecast for Southwestern Oregon

Air Quality Report for Southwest Oregon                                                               Issued: August 27, 2015


Synopsis:
Fires:  The following fires are contributing to the smoke in Southwestern Oregon.  In California, most of the smoke in the Gasquet Complex is coming from the Bear Fire and the Peak Fire.  Crews will continue strengthening lines and conducting burn out operations on the Bear Fire.  The Peak Fire is burning in the Siskiyou Wilderness. The Collier Butte Fire has moderated this burn period.  Most of the fire activity is in the Collier Creek Drainage.  On the National Creek Complex, mostly backing and creeping spread is occurring, with some single tree torching and short range spotting. Minimal fire behavior is occurring on the Stouts Creek Fire.
Air Quality Today:   One more day of moderate to unhealthy air quality is expected, where Medford, Jacksonville, and Klamath Falls will receive the greatest impacts.  Roseburg and Brookings, however, will have good air quality.
Air Quality Tomorrow:  Improved air quality across the region is expected as cooler temperatures and high relative humidity will cause fire behavior to diminish.   Rain is expected on Saturday morning.

8/27/15: Air Quality Report for NE Oregon and surrounding areas

Air Quality Report for Thursday August 27, 2015
NE Oregon, SE Washington and W Central Idaho            
Prepared by:  Greg Johnson, Air Resource Advisor
Wallowa-Whitman National Forest, Baker City OR

Afternoon winds yesterday helped clear smoke from many areas, but areas downwind of fires experienced increased smoke loads at the same time.  Hot temperatures, low humidities and wind caused extreme fire activity on the Teepee Springs fire, and all others were very active.  Smoke from the explosive growth of the Canyon Creek fire near John Day spread smoke northward yesterday evening well into Baker and Union counties.  Smoke from the Grizzly Bear fire on the OR/WA border kept locations like Lewiston and Troy in the smoke most of the day.  Extremely smoky conditions and hazardous air quality continued in Riggins (from Teepee Springs fire), as well as some locations in the Nez Perce area (Kamiah).  Today will see temperatures again well into the 80s and 90s (Riggins reached 104 yesterday), likely leading to fire growth again.  Smoke production on most fires will be in full force today, so locations downwind of fires will again be very smoky.  Winds will increase on Friday and continue fairly strong through Sunday.  This will lead to much better dispersion, and areas just downwind of fires will probably be the only areas with extremely bad air quality this weekend.  It also will be much cooler Saturday, continuing through next week.  Unfortunately, most of this region will not have any significant rainfall for the next 5 days.

AQI Index
Actions to Protect Yourself
Good
Air quality is considered satisfactory, and air pollution poses little or no risk.
Moderate
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms.
Unhealthy for Sensitive Groups - USG
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air
Unhealthy           
Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects.
Very Unhealthy
 
This would trigger a health alert signifying that everyone may experience more serious health effects.
Hazardous
This would trigger a health warnings of emergency conditions. The entire population is more likely to be affected.
