We have started plotting the weather for this season already. It gives us an indication as to what is going on with the snowpack, particularly how the weather is contributing to stability or instability. From direct weather effects on the snowpack we can get an idea what is going on with the snow surface. There are 4 of these;
Wind can transport a large amount of snow which results in rapid loading of the snowpack. It can change the shape of snow grains and increase slab density.
Temperature and Sun changes the settlement and creep rate of the upper snowpack.
Rain or snow adds weight and therefore stress on any buried weak layer in the snowpack.
We have not been out skiing just yet, but when we do we will have some knowledge of the snowpack already through our weather chart.
