Avalanche Summary

When the sun comes out and temperatures rise during the day, loose wet avalanches will be possible on sun-affected slopes.On Friday, there were reports of a few size 2 loose wet and wet slab avalanches on southerly aspects.

Snowpack Summary

Sun exposed slopes in the alpine and on all aspects at treeline and below are becoming moist to wet during the heat of the day. In these areas spring conditions are in effect; the avalanche hazard will fluctuate greatly depending on the strength of the overnight freeze and how quickly the snowpack is warmed up each day. Dry snow may remain on shady slopes in the alpine. In these locations, 50-100 cm of snow sits on a layer of facets (sugary snow) that was buried around March 10th.
