The snowline is the main determining factor in avalanche hazard. Where precipitation predominantly falls as snow storm and wind slab avalanches will be likely.
Keep an eye on new snow amounts as you move through terrain.
We have uncertainty in the amount of snow vs rain.
Avalanche danger is highest where precip falls as snow.

By late Saturday afternoon up to 40 cm of new snow may have accumulated at higher elevations. This new snow will be accompanied by moderate southerly wind, forming deeper deposits on north aspects. Below this is a well settled snowpack made up of crusts and moist snow.

The snowpack depth at treeline is around 120 to 150 cm.
