Avalanche problems

  • Wind Slabs

    Size
    1–3
    We will have wind slab development in any exposed areas with the new snow and forecasted mod-strong west winds.  Failure of these may step down to the Feb. 10th interface.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood

    With the new snow, expect the Feb 10th layer of facets, surface hoar, and some buried sun crust to "wake up", especially in thin and variable snowpack areas. 

Weather Forecast

We are expecting 40cm+ West of the divide and in the Lake Louise, Bow Summit area, and 20cm + in the Sunshine area starting tonight.  This will be accompanied by moderate to strong westerly winds and warming temperatures.  We should see the storm leave the area by Monday morning.

Snowpack Summary

Strong west winds have created widespread wind effect in the ALP and at TL. Below 1500m a rain crust exists. The Feb.10th layer is down 50-110 and is still showing easy to moderate test results in thinner snowpack areas, and harder results in deeper snowpack areas. Areas with buried sun crust are especially touchy.

Avalanche Summary

No new avalanche observations today. We are still only just coming out of a major avalanche cycle
