Adding Rows to or Deleting Rows from the Weather Forecast (FSPro)

Fire Behavior Specialists or Super Analysts can add or delete one or more rows of daily weather forecast data when working from the ERC Stream Menu Option in FSPro. The fields in each row can be populated manually or data can be pulled from the National Weather Service (NWS) Point Forecast Data. The more rows you add (i.e. the longer the forecast period), the fewer days of time-series generated climatological information of ERCs and subsequent fuel moistures are used and vice versa. Typically, more rows are used when there is greater confidence in the weather forecast and fewer rows are used when there is less confidence in the forecast.

One caveat to using the forecasted weather is that the ERC (and subsequent fuel moisture, burn period and spotting probability) are held constant for those days in the simulation cycle. For example, if 1000 fires are modeled for 7 days with 3 days of forecast, the first 3 days of every 7 day simulation (for 1000 simulations) will show little FSPro output variability for fires that do not exhibit crown fire and spotting. It is recommended to allow FSPro to use time-series generated ERCs for a majority of the simulation period to create a probability map with variability. As a general rule, don't add more than 3 lines of forecast weather to a 7 day simulation; or don't add more than 5-6 days of forecasted weather for a 14 day simulation.

To add rows to the Weather Forecast:

  1. From the Analysis list, select the incident/analysis name that you want to run an FSPro Analysis for.
  2. Click View Information. The General FSPro Information page appears.
  3. Select ERC Stream from under the FSPro Information menu on the left-side of the page.
  4. Add one or more rows under the Weather Forecast bar by completing one of the following actions:
  5. Click Add Row and type the ERC, Speed, and Direction data if not automatically retrieved from National Weather Service (NWS) Forecast Data. Add additional rows as needed by repeating this step.
    • From the National Weather Service Forecasts drop-down list:

      Select additional days from the Days drop-down list.

      Click Get NWS Forecasts.

  6. Click Save Stream and Forecasts.
