Abstract: Located in the Coast Mountains, Bear Pass comprises of extensive avalanche terrain impacting Highway 37A with significant potential to isolate coastal communities. To successfully monitor and mitigate avalanche hazard, daily avalanche path per path forecasting has been employed which allows forecasters to maintain a record of the variability of each avalanche path’s previous weather and snowpack conditions, natural avalanche occurrences and mass reduction from explosives control. The interactive application has been developed to geospatially highlight areas of concern and conveys expected avalanche activity character, size and subsequent consequences at the highway-avalanche path interface. Alongside daily assessment, it provides the opportunity for continuous and instantaneous geospatial updates to hazard, expected avalanche activity, avalanche hazard trend, character, previous occurrences and control. It further facilitates an easily accessible communication platform for program forecasters, which can then aid in communications with stakeholders, emergency response agencies and maintenance contractors by providing detailed guidance on how, where and why highway incidents and maintenance can be managed within operational procedures.
