Continually assess for changing conditions - the upper snowpack and avalanche hazard can change surprisingly quickly this time of year if the sun makes an appearance or we receive more snow than expected.

Avalanche Summary

Multiple natural loose wet and slab avalanches up to size 2.5, have been reported from the Coquihalla area, generally failing on steep rock slab features at lower elevations.

If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.

Snowpack Summary

On the surface is a widespread melt-freeze crust existing on all aspects at treeline and below, along with solar aspects at all elevations. This crust is unlikely to breakdown Thursday with cooler temperatures and cloud cover forecast. The surface snow in northerly-facing alpine terrain remains generally cold and dry.

The mid and lower snowpack consists of a number of old crusts and facetted snow that continue to be tracked, particularly in shallow snowpack areas, although, currently are not of significant concern.

Terrain and Travel Advice

Make observations and assess conditions continually as you travel.
A crust on the surface will help bind the snow together, but may make for tough travel conditions.
Pay attention to cornices and give them a wide berth when traveling on or below ridges.
