Issued by Ryan Lewthwaite -

bottom line:

The snow conditions have taken a more stable form for recreation today.  A beautiful day awaits those who come to the BWRA, with sun & the anticipation of new snow. A lower potential for Persistent Slabs still lingers in the snowpack where loading on steep N-E slopes has occured. Normal Caution is a good time to practice companion rescue skills & impress your buddies with your ability to save them.

Avalanche Character 1: Normal Caution
Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features. Use normal caution when travelling in the backcountry.

Time has allowed the snowpack to find its place on the hills. Although the dynamics of our snowpack should keep you on your toes as isolated complications may exist below your chosen sliding device. It is still worth mentioning the Persistent Slab issue we have found this week & its potential for avalanches. Use wise judgement & don't put your crew at risk. 

Snowpack Discussion

An improvement to stability has come just before another bout of precipitation arrives. The Pesistent Slab issue has not completely disintegrated, so keep it in your thoughts while we get new precipitation. Stability tests performed yesterday indicate the snowpack is gaining strength, although isolated features in loaded areas still pose a hazard of avalanches. Spatial variability of the snowpack is high & you should take the time to educate yourself with what's underneath you.
