    As temperatures rise and the snowpack warms during the day, the likelihood of loose wet avalanches will increase, especially in areas with fresh snow.

Avalanche Summary

There have been no recent avalanche observations in the forecast region.

Snowpack Summary

Sun exposed slopes in the alpine and all aspects at treeline and below have become 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 still be found on north-facing slopes in the alpine. At these locations, 30-50 cm of well settled snow overlies a layer of facets (sugary snow) that was buried around March 10th.
