    When the sun comes out and as temperatures rise during the day, the likelihood of loose wet avalanches will increase on sun-affected slopes, especially in areas with fresh snow.

Confidence

Moderate - Intensity of incoming weather systems is uncertain

Avalanche Summary

There have been no recent avalanche observations in the 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. With spring conditions, 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 north-facing 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.
