To run an automated STFB:
- From the Incident List page, select the incident you want to run a short-term fire behavior analysis for.
- Click Assess Situation. The Situation page appears showing the map of the incident area.
- Select the
Landscape Extent icon from the Map Tools. - Draw a landscape extent on your map around the incident. This is the area of the analysis.

Refreshes map layer
Accesses the online help for the selected item.
Creates a new analysis.
- Click the green + icon. The list expands.
- Enter a Name for the STFB you are creating.
- Enter a Burn Date. The analysis uses the weather and forecast data available for this date.
- Enter the Burn Time in 24-hour format (hh:mm). The analysis uses the time to determine what the fire is likely to be doing (e.g., a burn time in the morning will give different results than one during the heat of the day).
- Enter the Latitude and Longitude for the analysis start point. (Be sure to enter a positive number for Longitude.)
Note: If you don't know the latitude or longitude, click the Info
button on the mapping tools. Then, clcik the location on the map where you want the analysis ignition to start. The Info tab displays the latitude and longitude that you selected. When you return to the Map tab, the latitude and longitude fields are auto-filled with your selection. - Enter the hours in a Burn Period and the number of Burn Periods to use in the analysis.
- The hours in the burn period start with the burn time; e.g., if you start the burn time at 15:00 and select a burn period of 3 hours, the model uses 15:00-18:00 as the burn period.
- If you choose more than one burn period, the model uses that number to determine how many days it will examine during the selected burn time; e.g., if you set the burn time and period as above and then select 3 for the number of burn periods, the model will look at 3 days during 15:00-18:00 to determine the output.
- Click Next. WFDSS displays the wind data for the selected date and time. You can edit these data if necessary.
- Click Run Model. A message appears stating that the model was successfully sent for processing. When the run is complete, the STFB appears in the STFB list and the results appear on the map.
- To view more details, click the + next to the name of the STFB you just created and select one of the options listed. The map changes to display each option selected.
Depending on the load on the system, it could take several minutes for the run to complete. If you don't see results, try refreshing the page and zooming in.
