Abstract: The number and severity of snow avalanches is directly related to the amount and rate of snowfall (Perla and Martinelli, 1976). Avalanche hazard evaluation and control may be facilitated by timely and accurate forecasts of those meteorological parameters that contribute to avalanches and snow metamorphism. In Canada, the Department of the Environment, Atmospheric Environment Service (AES) has been assigned the responsibility to provide these forecasts. In 1970, the Warden Service of Parks Canada at Banff National Park requested the Alberta Weather Office (AES) to provide daily weather forecasts in support of avalanche control activities. These forecasts were to be for 24 hours, with a further outlook for the following day. Initially, the forecasts were mostly subjective, based on the meteorologist's knowledge and experience. It soon became apparent that a more systematic and objective technique would have to be developed to give guidance in the area of quantitative precipitation forecasting. This paper will describe the approach taken to develop the technique.
