Highlights

Be on the lookout for new wind slabs forming in the alpine with the forecast winds and new snow.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2

    New wind slabs forming on previous hard surfaces (sun crusts and old wind slabs) will likely need some time to bond.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1.5–3.5

    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.

Confidence

High

Avalanche Summary

Small spin drifts and loose dry avalanches out of steep alpine terrain were observed in the icefields area on Monday.

Snowpack Summary

5cm of new snow with moderate to intense wind transport in the alpine. Solar slopes and all aspects at tree line and below have a plethora of crusts in the upper snow pack. The Feb 3 PWL is down 40-100cm and remains a concern on shaded aspects above 2400m . The basal depth hoar/facets are gaining strength in deeper snowpack areas.
