Snowpack Summary published on March 21, 2019 @ 10:20 am
Issued by Ryan Lewthwaite -

bottom line:

The snowpack is still holding onto winter with small accumulations & cold temperatures overnight. Last weeks warmth hasn't transitioned into terminal spring yet, but we are not too far out. Keep small wind slabs as the main highlight in the group travel plans & act accordingly.

Avalanche Character 1: Wind Slab
Wind Slab avalanches release naturally during wind events and can be triggered for up to a week after a wind event. They form in lee and cross-loaded terrain features. Avoid them by sticking to wind sheltered or wind scoured areas.

Light Southwest winds will put the 2" of new snow to Lee aspects & terrain features. Any transport will be minimal but the possibility still exists for small avalanches in wind loaded areas. Cornices could grow & become more tender if winds & precipitation increase.

Snowpack Discussion

Our snowpack gained 2 inches in the past 24 hours which has bonded well to the old surface. Light SW winds will put any loose snow onto Lee aspects. The snow depth & recent warmth has helped stregthen our snowpack overall. Tuesdays snowpit in the Low-Ball bowl revealed good structure & no instabilities within compression tests (CTN x2). Melting of the surface snow to 10cm in depth has allowed for a good bonding scheme with any new accumulations. The snowpack depth in variable but some areas have well over 350cm.

recent observations

~Yesterdays new 2" was enjoyable. Light SW winds have not transported all the new snow but it will try. Good overall stability.

~Tuesday we saw minor activity in the surface snow as it was melting. HS +325cm CTN x2
