Issued: Apr 4th, 2019 3:26PM

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.

Minimize exposure to steep slopes as temperatures warm through the day, especially in areas with fresh snow.

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.

Problems

Loose Wet

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.

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.
