Ignition susceptibility
No susceptibility surface is available. A hot, dry or windy forecast alone cannot identify where a fire will start.

Conditions to investigate
National Weather Service · Point forecast
Weather context not loaded
Refresh public sources to request published forecast periods. No weather values are assumed.
Potential rapid growth
Review weather alongside measured fuel moisture, terrain and surface/canopy fuels before model interpretation.
Inputs incomplete02 / Active fire
Scenario input brief
Choose a reported incident, or supply a dated perimeter. Both remain inputs for review—not a modeled fire path.
Incident locations are not perimeters. Feed records may include prescribed fires or other incident types.
Optional perimeter input
Maximum 1 MB / 10,000 vertices. Processed only in this browser; never uploaded.
No perimeter supplied.
Model-backed spread unavailable
No spread engine is connected. Even a structurally valid perimeter does not unlock a forecast.
- Verify perimeter provenance, observation time and topology.
- Add terrain, surface/canopy fuels and measured fuel moisture.
- Provide time-varying weather for the scenario.
- Run a validated model with qualified review and uncertainty reporting.

Methodology & what is needed next
This research preview assembles published context and user inputs. It performs no wildfire simulation, risk scoring, satellite ingestion or AI forecasting.
US Forest Service: FlamMap / FARSITE ↗ — constant environmental conditions for FlamMap/MTT; time-varying weather for FARSITE. Relative potential behavior is not an ignition probability.
LANDFIRE landscape inputs ↗ — elevation, slope, aspect, fuel model, canopy cover, canopy height, canopy base height and canopy bulk density. These inputs are not connected here.
Briefing exports preserve source URLs, request and publication times where supplied, weather periods, selected incident, local perimeter inputs and missing requirements. They are input records, not forecast reports. Downloaded files contain your supplied inputs; share deliberately.
