WFDSS STFB - What it does (outputs)

Following 7 days of fuel moisture conditioning, the WFDSS Short-Term Fire Behavior (STFB) model uses one set of gridded wind and fuel moisture conditions (based on the analysis start time) for the simulation duration to calculate and display two fire spread outputs:

• Arrival Time: represents the number of hours it takes the fire to reach that location on the landscape from the ignition source
• Major Paths: shows only the most significant fire spread pathways

Automated STFB Outputs showing Arrival Time and Major Paths

In addition to the fire spread outputs described above, when a STFB analysis is conducted, Basic Fire Behavior (BFB) "snap shot in time" outputs are also calculated for the defined landscape extent using the start date and time, and are available for display.

Note: The Wind Direction and Wind Speed outputs are a product of WindWizard. These 20' gridded wind values are used as an input for STFB, but STFB itself does not produce wind direction or wind speed outputs.
