    Repeated warming/cooling cycles are helping stabilize these layers. Continue to watch steep polar aspects where the warming cycles are fewer and less intense.

Avalanche Summary

Several loose wer avalanches up to size 1.5 were observed, likely solar triggered.

Snowpack Summary

As of Tuesday afternoon, there was a crust up to 2350m on non-solar aspects. Moist snow went up to mountain top on solar aspects. This will likely freeze to a crust before the 5-10cm of snow arrives and could become an easy sliding layer. Take the time to evaluate this interface before commiting to the terrain.

The March 24th crust interface has significant faceting above the crust. This layer is buried 40cm at TL and produced variable test results from moderate to hard.

Weather Summary

5-10cm of snow is ecpected to fall sometime Tuesday morning. The temperature in the alpine is forecast to stay cool around -7c. Winds will be in the 40-70km/hr range from the SW.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the crust.
  • Be alert to conditions that change with elevation and sun exposure.
