Snowpack Summary
The classic melt freeze cycle has come to an end with cloud and warm temps preventing a good refreeze in most of the forecast region. Along with the solar aspects, previously dry north facing zones in the alpine are also now moist. A buried rain crust can be found down 25-50 cm and exists up to around 2100 m. Larger triggers such as a loose wet slide, or cornice fall may cause this layer to fail. Snow may be isothermal on south facing aspects in the alpine/treeline and on all aspects below treeline.
