There are still concerns in wind-loaded areas and thin spots. There is a lot of variability with respect to aspect and elevation right now, so take some time to assess the snow where you are.
Summary
Weather Forecast
Friday - cloudy with light precipitation and moderate temps. Saturday - the wind shifts to north or northeast and will give us a brief taste of cold winter again.
Snowpack Summary
The snowpack is variable by aspect and elevation. Deep facetted weaknesses are still common. Westerly aspects have been wind-hammered and lee (east) aspects near ridge crests should be suspect. From treeline down, breakable melt-freeze crust transitions to bullet proof melt-freeze crust. Nasty.
Avalanche Summary
No new avalanches were reported today in Little Yoho.
Confidence
Problems
Wind Slabs
Recent winds from many directions have formed wind slabs that are susceptible to human triggering. Recent cornice growth is also a concern as these may trigger any deep weak layers that are present in the snowpack.
- Extra caution needed around cornices with current conditions.
- Use caution in lee areas. Recent wind loading have created wind slabs.
