Points saillants

Crusts dominate the solar aspects but dry snow is still being found on the polar aspects.  Its not full on spring, stay on gaurd for thin weak areas and windslabs along ridgelines.  If the sun comes out, stability will det'r quickly!

    Fresh windslabs in alpine areas along ridgelines and crossloaded features.  Watch for these at the entrances to runs.

    Overhead cornices loom along ridgelines.  As daytime temps warm up, these will become weak and have potential to collapse.

Snowpack Summary

Convective flurries over the past 24hrs have given us an additional 5cm of snow that has fallen with very little wind.  Over the past few days 20-25cm of new snow has fallen that has had generally very light winds.  Isolated windslabs are being encountered in Alpine areas up to 40cm thick.  We are also still having concerns regarding thin weak areas where the basal areas may still be reactive.  Despite it being spring, keep a keen eye on snowpack depths as you travel.  Heat plays a large role at this time of year, solar aspects and quality of overnight freeze are critical things to be thinking of so pay attention to these concepts as you travel.  The best skiing is being found on polar aspects where there are no crusts.

Weather Forecast

Convective flurries are forecast to continue over the next 24hr with accumulations around 10cm.  Freezing levels will be around 2100m with temperatures in the alpine around -5C.  If the sun does come out solar radiation will quickly decreased the stability on solar aspects so be sure to stay tuned into local weather patterns during the day.

Avalanche Summary

No new avalanches were observed or reported into the forecasting office over the past 24hrs.
