Ranks burned watersheds by post-fire debris-flow susceptibility from free public data — for fires that never get a formal USGS or state assessment. Auto-acquired 3DEP terrain + dNBR, D8 delineation, burn × slope × area scoring. Validated on Thomas Fire → Montecito. A within-fire relative ranking, never a prediction.
