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 SOUTH CENTRAL OREGON ZONES 624 AND 625
SHORT-TERM
DISCUSSION
NW flow aloft weakens on
Thursday as a ridge begins to build offshore.
Sunny and warm temperatures are expected, about 5oF above seasonal.
Afternoon mixing will be good with light and variable winds but favoring
NW-N by afternoon and evening.
EXTENDED DISCUSSION
The offshore ridge is
fully in control by Friday. Sunny and
warm conditions continue. Burning conditions will be good in
the afternoon with very light NW-N winds.
Little change is expected for the
weekend. The ridge building nears its peak

above normal continue. Mixing heights on
both Saturday and Sunday will be high with very light winds, mainly favoring NE.

afternoon then lowers below 1000 ft during the evening.
Transport wind
light and variable and controlled by local terrain during the morning. Transport wind increases to WNW to NNW at 4 -
8 mph during the afternoon then shifts to NNE to ENE at 6 - 10 mph during the

3. BURNING
INSTRUCTIONS FOR ZONES 624 AND 625 INCLUDING THE WALKER
RANGE PORTION OF ZONE 624
- Valid for burning done Thursday, June 11,
2026.
==================================================================
Follow standard
guidance matrix - see section 5 below - for burning units to the WNW through
ENE of SSRAs. For units that will
smolder significantly through the night avoid burning within at least 25 miles
to the WNW through ENE in or near drainages leading to SSRAs. Verify transport winds away from SSRAs if
burning in any other direction. No additional restrictions necessary.
==============================================================
4. SPECIAL NOTE:
The smoke management forecaster is
available at (503)
945-7401.
The smoke management forecaster is available
to discuss specific burns. The duty forecaster phone
number is (503) 945-7401. Please call this
number and
not individual's numbers to discuss daily
burning. Please
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.
