    This problem seems to be most active where the March 19th crust is not supportive over the Feb 3rd weak layer (down 30-90cm) of facets over a crust. Northerly aspects between 1900-2400m seem to be the problem area.

Avalanche Summary

Loose wet natural avalanche activity in the afternoons continues.

Snowpack Summary

5-10cm of soft snow can still be found in the shaded alpine. Solar aspects have multiple crusts within the upper 30 cm. A total of 20-40cm of snow now sits over the March 19th crust which is present everywhere except North aspects above 1900m. The Feb 3rd crust interface is down 30-90cm. Basal depth hoar and facets make up the bottom of the snowpack. HS ranges from 560 to 150cm.

Weather Summary

Monday: Cloudy skies and flurries at higher elevations. Southwest ridgetop winds will range from 35 to 50 km/h. Precip will be mainly on the windward side of the Rockies but some snow will drift across to the eastern slopes through the afternoon. Freezing levels will be 1800-2000 m.
