Abstract
A special weather bulletin is produced during the winter season at the Pacific Storm Prediction Centre (PSPC) in Vancouver to support avalanche forecasting efforts in British Columbia. This paper will present a history of this Canadian Avalanche Centre (CAC) bulletin and trace its usage. Verifications are examined. Major forecast busts and hits are examined for several situations related hazardous avalanche conditions in BC – most notably strong southwesterly flows and stalled frontal bands. Weather variables which are most important for improved avalanche safety are identified for each region and suggestions made for how probabilistic ensemble forecasting may improve weather forecasts. The value of direct communication with a trained forecaster is shown through the time-honored traditions of the technical synopses (short term and extended), confidence statements and daily phone briefings. Future improvements will depend on how well we can build upon existing expertise while better communicating new advancements to avalanche professionals and those whose safety depends on accurate mountain weather forecasts.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
