Snowpack Summary

The region is expected to receive 10-15 Wednesday night through Thursday, which will add to the previous 15 to 30 cm of storm snow accumulations since Monday. This new snow rests on previously wind hammered snow, sun crusts (on solar aspects), and sugary facets. February's cold weather weakened the upper- and mid-snowpack. In some sheltered areas, 20-50 cm of the snowpack was faceting, or sits on facets (sugary snow),In the south of the region, the lower snowpack is generally strong.
