Understanding avalanche problem assessments: A concept mapping study with public avalanche forecasters
Bibliographic record
Abstract
Avalanche problems have become a fundamental component of avalanche hazard assessment and communication since the introduction of the Conceptual Model of Avalanche Hazard. However, the observations used to assess them are not explicitly defined and rely largely on avalanche forecasters’ subjective judgements that are prone to noise and bias. This study uses concept mapping to develop a comprehensive understanding of factors influencing operational applications of avalanche problems in public avalanche bulletins in Canada. Interviews with 22 experienced forecasters revealed a diverse range of physical observations and additional considerations. While some of the observed inconsistencies can be attributed to physical differences among forecast regions, others originate from personal perspectives on risk communication considerations, approaches to dealing with uncertainty, and attributes of operational forecast systems. This research offers a starting point for the development of more objective criteria for adding and removing avalanche problems in public bulletins.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
