Ultimate Objectives
Produce seasonal wildland fire potential outlook
Develop standard content and protocols
Improve use of climate products and forecasts
Encompass both process and product
$2B/year in federal fire suppression even if there’s no big event!!

Stakeholder-driven Climate Science/Services Research Process
![Page 4: The Making of National Seasonal Wildland Fire Outlooks](https://reader035.vdocuments.site/reader035/viewer/2022070412/56814907550346895db63ec3/html5/thumbnails/4.jpg)
Workshop goals
Increase organizational capacity
Enhance multi-agency collaboration
Improve use of forecast information and climatological
analyses
Transition results of research to an operational process for
improved communication and decision making

Workshop participants
Fire weather meteorologists
Fuels specialists
Fire specialists
Fire management
Climatologists
50-60 participants last year (beyond
committee size)

Seasonal Fire Outlook Content- it’s a package of items, not just a map
Executive summary
Introduction and objectives
Current conditions
Climate outlooks
Fire occurrence and resource outlooks
Future scenarios and probabilities
Management implications and concerns
Summary and recommendations
![Page 8: The Making of National Seasonal Wildland Fire Outlooks](https://reader035.vdocuments.site/reader035/viewer/2022070412/56814907550346895db63ec3/html5/thumbnails/8.jpg)
Monitoring of current climate conditions
Temperature/precipitation anomalies: mid & high
elevations, complex terrain
Snow: complex terrain, departure from usual
ENSO:multiple definitions are an issue
Circulation: more upper air observations
Drought indices: multiple definitions (impact-based vs.
hydro-based), soil moisture, scale
Protocol/Needs
![Page 9: The Making of National Seasonal Wildland Fire Outlooks](https://reader035.vdocuments.site/reader035/viewer/2022070412/56814907550346895db63ec3/html5/thumbnails/9.jpg)
Monitoring of current fire & fuel conditions
Fire danger
Vegetation greenness:NDVI, land surface conditions
Fuel moisture: presently use algorithms, not in situ
observations
Fire occurrence: data is abysmal
Fire behavior: highly local
Protocol/Needs

Outlooks/forecasts/predictions
Relating episodic conditions to climate conditions, lightning,
monsoon
Long-range temperature/precipitation
Circulation: synoptic patterns & CPC outlooks
ENSO
Drought forecasts
Soil moisture forecasts
Fire weather/danger indices
Protocol/Needs

Future Scenarios Fire Family Plus tool: historical review + analog weather generator
Priority sub-regions within Geographic Area: mortality areas PJ dieoff, pine bark
beetle
Fuel-type considerations: carryover fuel, effects of snowcover (e.g., on standing
grass)
Climate considerations: 4-6 years ago + future
Season ending event probabilities: e.g., abrupt or slow evolution of cool/wet
conditions
Focus on analogs: need ‘best practices’ guidance

Fire Outlooks
Seasonal fire occurrence/activity estimates
Estimates of expected resource needs: for
suppression, prescribed burning, fire use
(plans for letting natural fires burn).
Protocol/Final Product
Will fire managers give up resources for other regions
If so, is it based on climate or fuels considerations?
Measure of Success

Late Feb 2003
![Page 14: The Making of National Seasonal Wildland Fire Outlooks](https://reader035.vdocuments.site/reader035/viewer/2022070412/56814907550346895db63ec3/html5/thumbnails/14.jpg)
White area means we need more research, not that the forecast is for ‘normal’ conditions.

Colors indicate at some point during the period, not necessarily for the whole period.

Future of Product and Process
Post-mortems and verification:
how to verify shift in risk (fire potential), when the risk lacks good
definition?
Evolution of product
Process continues to advance:
Community actually using climate outlooks in a formal process
NICC investing in training workshops for GACC meteorologists
(information intermediaries). Will decision makers participate?
