In sintesi

Pay attention to rising freezing levels and solar inputs throughout the day. If the sun comes out things will warm up quickly and the hazard will increase.

Snowpack Summary

3-5 cm of fresh snow at upper elevations with some wind effect and thin wind slabs in isolated areas. Various types of temperature crusts or moist snow found on solar aspects and found on all aspects below 1900 m. The March 15 suncrust is down 25-50 cm on solar aspects and still is a concern for skier triggering.
