We
Need Your Feedback!
The Smoke Management
Department is planning to “upgrade” this product so that it more effectively
meets your needs. To assist us with this project, we are requesting
feedback from you!
Below are a few questions
to help you consider what changes would be most beneficial for
you. All ideas are welcome!
Is the “Short-Term
Discussion” useful? What would enhance it?
Is the “Long-term
Discussion” useful? What would enhance it?
How could the “Dispersion”
forecast better meet your needs?
Is the “Outlook”
useful? What would enhance it?
Are the “Burning
Instructions” clear and concise? How could they be improved for your
use?
How do you access the
forecast product (i.e., Email; web page; telephone recording)?
We are considering
discontinuing or upgrading the phone recording of the forecast
product. Is that something you currently use? Would you
use it if you could get your specific forecast from it faster?
Please Email your feedback
to: Peter.GJ.Parsons@odf.oregon.gov
Thank you!

1. DISCUSSION AND
FORECAST FOR NORTHEAST FORECAST AREA ZONES 637-646
SHORT-TERM
DISCUSSION
An upper-level ridge builds just
offshore through the weekend to cause sunny skies and a warming trend,
temperatures 5-10oF above average.
Mixing conditions improve through the afternoon on both days with N-NE transport
winds.
EXTENDED DISCUSSION
The ridge remains and peaks on Monday for little change in
conditions except even warmer. Mostly sunny
skies push temperatures 10-15oF above seasonal.
Mixing conditions will be very good with NW-N winds.
The ridge weakens by Tuesday and flow aloft will be WNW, but skies remain mostly
sunny while there is little change in temperatures. Good mixing conditions remain with W-NW
winds.

4. SPECIAL NOTE:
The ODF forecast
smoke zones differ from the NWS fire zones and
are available at:
https://www.oregon.gov/odf/fire/documents/smoke-forecast-zone-map.pdf
The smoke management forecaster is
available at (503)-
945-7401. Please call this number and not
individual's
numbers to discuss daily burning. For large burns (over
2000 tons) or burns extending over a
considerable period,
please request a
special forecast. Avoid calling
between 1:30 to 2:45 p.m.

5. STANDARD GUIDANCE
MATRIX:
* Greater than 5000 ft mixing height: Limit
to 150 tons per mile
from downwind SSRAs.
Example: 75 tons allowed if burned a half
mile from a downwind
SSRA.
* 3000 - 5000 ft mixing height: Limit to 50
tons per mile if
burning within 5 miles of downwind SSRAs.
Limit to 100 tons
per mile if burning 5 miles or beyond
downwind SSRAs.
Example #1: 200 tons allowed if burned 4
miles from a downwind
SSRA.
Example #2: 500 tons allowed if burned 5
miles from a downwind
SSRA.
* Less than 3000 ft mixing height: No burning
within 5 miles of
downwind SSRAs. Limit to 60 tons per mile
from downwind SSRAs.
* Ensure adequate spacing between units when
burning near downwind
SSRAs.
* Use of polyethylene (PE) sheeting on
greater than 75 percent of
piles in a unit with 60 percent coverage
per pile will allow a
50 percent increase in tonnage over the
existing instruction tonnage
for that zone.
* All exceptions must be coordinated with the
duty forecaster
prior to ignition.
6. BURN MONITORING:
Burns over 2000 tons must be monitored (OAR
629-048-0230(3) -
7/1/14). Monitoring of all burns is highly
recommended for both
smoke management purposes and wildfire
potential.
