To run an NTFB:

1. From the Incident list, select the incident for which you want to run NTFB.
2. Click View Analyses. The Analysis List appears for the selected incident.
3. Under New Analysis, select Near-Term, then click Create Analysis for Incident. The New Near-Term Analysis page appears.
4. Enter an Analysis Name. The analysis name cannot contain an apostrophe or backslash; the cursor blinks if you try to add these characters and a message displays that these characters are disabled.

   Since incidents can have many analyses associated with them, be specific in your name (up to 48 characters).

5. Set the conditioning days, spotting probability, and crown fire method. There is generally no need to change the spotting seed.
6. Set the spot ignition delay and foliar moisture content.
7. Set the start and end dates.
   • For dates in the future, WFDSS uses forecast data.
   • For dates in the past, WFDSS uses historic RAWS data.
8. Upload ignition and barriers shapefiles. An ignition file is required; barriers are optional. If no ignition file exists, you can create it later (See Creating an Analysis Ignition File).
9. Verify the RAWS station information.
10. Click Create. The Detailed Near-Term Fire Behavior page appears. You can modify any information that was added in steps 4 - 9 here.
11. Verify the following items:
    • burn periods (typically, analysts will shorten the burn duration from the default 24 hours to the timeframes of active burning)
    • wind information
    • initial fuel moistures (herbaceous and woody fuel moistures typically need adjustment)
    • hourly records (wind and weather)
12. Click Save after making edits and before leaving the Near-Term Information Page.
13. Create a landscape file and edit it if necessary. (See Creating the Landscape File and Editing a Landscape File.)
14. Use the Requirements fly-out menu on the right to ensure all required components are completed.
15. Click Run Near-Term Fire Behavior.The analysis runs. Depending on the parameters you selected, the analysis could take several minutes to complete.

Depending on the landscape size and resolution, as well as the traffic on the server, the analysis could take several minutes to run. Refresh your browser to see the status change to Complete, then select the analysis and click View Results to see the analysis on the map view.
