Points saillants

The winds are loading slopes rapidly. Even though the storm was a downer, the ongoing wind loading is worth some serious consideration. The storm snow is warm and heavy...perfect for building windslabs.

Problèmes avalancheux

    These slabs are buried below the new snow. The rapid loading may overwhelm the bond with the deeper layers.

    lots of action today in steep rocky terrain. If the snow keeps coming expect this problem to get worse tomorrow. Watch gullies and confined areas.

    Today these slabs built very quickly with the warms temps. We can expect the same tomorrow. A natural cycle is expected in the alpine. Avoid overhead exposure regardless of your activity.

Confidence

Fair - Timing, track, or intensity of incoming weather system is uncertain

Weather Forecast

Some more snow is expected as this system tapers out. The forecasts are saying another 7 tonight and 10 tomorrow. The winds are expected to calm slightly, but the gusts will stay in the extreme range (80km/hr). The wind direction will be from the SW & W. Freezing level will climb to 2000m tomorrow. 

Avalanche Summary

Natural activity included loose dry & fresh storm slabs up to sz 2.0 on east aspects.

Snowpack Summary

The recent storm appears to have fizzled out. New snow amounts vary from 10cm to 25cm through most of the forecast area. The strong winds that accompanied the snow created fresh storm slabs on N-SE aspects. These slabs are expected to be as low as treeline in most places. The warmer temps have encouraged settlement within the storm snow. At lower elevations, settlement slabs likely exist.
