Abstract: In avalanche forecasting there are so many weather variables that effect the snow, it is often hard to decide whether to do avalanche control or not. Do you need to do avalanche control every time you receive new snow? Is there a set amount of snow that constitutes avalanche control? Many times I have gone over these questions in my mind and many times I have gone out on avalanche control and realized it was not necessary. As far as avalanche control is concerned at Stevens Pass, we are not necessarily concerned with how much new snow we receive, but how did and how are the weather conditions effecting the snow. Taking the US avalanche hazard rating scale developed by the US Forest Service, I decided to give each of the rating categories- LOW MODERATE - CONSIDERABLE - HIGH EXTREME - a corresponding set of parameters. Although I still have a hard time with the term, considerable', is it considerable-moderate or is it considerable-high or should it be considerable or should it be moderate-high? No big deal, I have learned to adjust considerably.
