Trend effects on perceived avalanche hazard
Risk Analysis, 2022 AbstractHazard‐level forecasts constitute an important risk mitigation tool to reduce loss of economic values and human life. Avalanche forecasts represent an example of this. As for many other domains, avalanche risk is communicated using a color‐coded, categorical risk scale aimed at informing the public about past, current, and future risk.

Travel and terrain advice statements in public avalanche bulletins: a quantitative analysis of who uses this information, what makes it useful, and how it can be improved for users [PDF]
Natural Hazards and Earth System Sciences, 2022 Recreationists are responsible for developing their own risk management plans for travelling in avalanche terrain. To help recreationists mitigate their exposure to avalanche hazard, many avalanche warning services include explicit travel and terrain ...
