Abstract: Current multivariate forecasting models make limited use of stability indices partly because the required manual measurements of snowpack properties are not available daily, Using 10 years of strength measurements of weak layers of faceted grains from two ranges in western Canada, a regression model is developed for estimating the strength of weak layers of faceted grains within eight days of manual snowpack measurements. Model testing shows promising results for the Columbia Mountains.
