The alpine rating is low, the treeline rating is low, and the below treeline rating is low. Known problems include Loose Wet.

dsaly, Avalanche Canada

Northwest Coastal.

Warm and sunny weather means that hazard will increase during the day as the sun comes out and temperatures rise.

Avalanche Summary

Last Friday, there were reports of a few size 2 loose wet and wet slab avalanches on southerly aspects.The likelihood of loose wet avalanches on sun-affected slopes will increase throughout the day as the sun comes out and temperatures rise.

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.

Problems

Loose Wet

When the sun comes out and temperatures rise during the day, the likelihood of loose wet avalanches will increase on sun-affected slopes.

Cornices become weak with daytime heating, travel early on exposed slopes.Avoid sun exposed slopes when the solar radiation is strong, especially if the snow is moist or wet.Avoid terrain traps such as cliffs and gullies that increase the consequence of small avalanches.

Aspects: East, South East, South, South West, West.

Elevations: All elevations.
