Central Avalanche Hazard Forecasting : Operating Manual : Methods and Equipment Developed During the Project

Description: The Central Avalanche Hazard Forecasting project has been funded by the Washington State Highway Commission since July 1975 in order to test the feasibility and effectiveness of central avalanche forecasting for the Cascade Mountain Passes and adjacent territory. Historically, avalanche forecasting in the Cascade Mountains has been done locally on an area-by-area basis by Highway Department personnel and by Forest Rangers and professional ski patrolmen at individual ski areas. This project explored the possibilities of improving both mountain weather and related avalanche forecasts for use by WSDT during winter operations in the mountain passes and, secondarily, explored the usefulness of an area-wide forecasting service to other, cooperating agencies. The aim of this work has been to establish the technical and administrative framework for an operational, on-going mountain weather and avalanche forecasting service for Western Washington under the joint support of interested public agencies. This aim has been achieved in autumn 1978 by the operation of an avalanche forecasting office administered by the US Forest Service, housed by the National Weather Service, and supported by WSDT, with additional peripheral support from both the public and private sectors.
