The future is hidden. Advance the storm hour by hour, and the moment the sky makes you uneasy, raise a flag — a live call, not a hindsight one. Then see how your read lined up.
This is a teaching instrument — not a forecast. These are reproducible simulated storm cycles shaped like real Avalanche Canada station data. They train pattern-reading. They are never a trip decision. The instrument's last word is always to send you to the snow, never to rate it.
