ASA: About this Data | Data Sources & How often we consume SFMS Data

**Describe the task**

Add to the ASA About this Data section

"A Fire Zone is under a Fire Behaviour Advisory if greater than 20% of the combustible land (trees, grass, slash) is forecast to have a Head Fire Intensity between 4,000 and 10,000 kW/m.

A Fire Zone is under a Fire Behaviour Warning if greater than 20% of the combustible land is forecast to have a Head Fire Intensity greater than 10,000 kW/m.

The [fuel types](https://cwfis.cfs.nrcan.gc.ca/background/fueltypes/c1) chosen for the text bulletin are the most common fuel types in a zone that meet or exceed the Fire Behaviour Advisory threshold of 4,000 kW/m."

**Acceptance Criteria**
- [ ] Data Sources
- [ ] How are weather forecasts incorporated into SFMS?
- [ ] How often we consume SFMS Data:
[ Legacy SFMS system runs 5 times per day. 8am and 5:45pm forecasts, and 3 actual/daily runs in the early afternoon (roughly 1:30, 2:30, 3:30pm) ]
- [ ] Add information re: our HFI Pixel Threshold:

**Next Steps**
- Asa Go About this Data will be updated in: https://github.com/bcgov/wps/issues/4777

Start with the ASA “About this Data” section and review the follow-up issue #4777, where this update is planned. Confirm that the data sources, SFMS weather-forecast use, consumption schedule, fire-behaviour wording, and HFI pixel threshold are documented there, then verify the completed section against the acceptance criteria.
