Kernpunkte

Carefully assess the bond between the new and old snow surfaces before stepping into committing terrain.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–2.5

    Wind effect and windslab are common through the region with some reactivity in the immediate lee.

  • Loose Dry

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Likely
    Größe
    1–2

    Ice Climbers, be cautious in areas where loading has stressed the snowpack. Top outs and ledges may be particularity sensitive due to new snow and transport winds.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    1.5–3.5

    Little recent activity on this layer. More likely to initiate this layer in combination with accidently triggering a surface instability. 

Weather Forecast

An arctic front, descending south through Alberta will change the low-level flow to the northeast bringing a steady temperature drop Saturday evening and some flurries but, little accumulation. A typically cool, mixed sun/cloud day for Sunday; light west wind and an alpine high temperature of -11.

Snowpack Summary

35cm of recent new snow appears to be bonding well to the old surfaces. Wind transport has been continuously forming soft wind slab on lee aspects. The Columbia Icefields region has a well bridged mid pack overlying basal facets and depth hoar. The northern forecast region is weaker and shallow; bridging over the basal weakness is less reliable.
