Points saillants

Invest some time and inspect the March 24th crust as you travel. We're noticing it starting to evolve into an avalanche problem as loose, sugary grains (facets) develop on top.

Problèmes avalancheux

  • Wind Slabs

    • Limite forestière
    • Sous la limite forestière

    1.5–2.5

    Variable wind directions have put these on all aspects. All open areas look heavily windloaded right now.

    This is a two fold problem. In high polar areas the older (and deeper) Feb 14th layer is still present and concerning, while in all other areas we have the evolving Mar 24 crust.

Avalanche Summary

We saw one sz1.5 loose dry that went today. Other than that, nothing new, but with the transport today, reloading was very quick.

Snowpack Summary

Lots of wind transport today at all elevations. Prevailing winds were SW which crossloaded many alpine slopes. Tree line and below had swirly, unpredictable winds that loaded up all aspects. Windslabs are widespread and vary in density from soft (4 finger) slabs at treeline to denser and thicker slabs in the alpine. There was some isolated cracking withing these slabs on the Mar 24th crust. Speaking of the Mar24th, it is everywhere, and thick. Today it was found as high as 2400m (our high point) where it was about 8cm thick and very firm. Lower down at 2100m it was down about 40cm and wasn't bonding especially well to the new snow. This will be the layer to watch as spring moves on. Solar aspects today were softening up by noon with pinwheeling reported on steeper, south facing ski lines.

Weather Summary

Morning low of -10, daytime high -1. The morning will have some thin cloud that will hopefully minimize the solar input, but still expect the sun to affect the snow on southern aspects. Winds will drop off a bit over the course of the day, but again expect some gusty winds and random, shifty wind directions. Snow? Nothing is expected.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
