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
A melt freeze crust exists on all aspects at treeline and below, and on solar aspects to mountain top. This crust is unlikely to breakdown with cooler temperatures and cloud cover forecast. The surface snow in northerly-facing alpine terrain remains generally cold and dry.
Convective conditions have the potential to deliver light accumulations of snowfall to isolated areas, which are challenging to predict. Moderate southwest winds may build small wind slabs on north and east facing terrain in these areas.
The mid and lower snowpack consists of a number of old crusts and facetted snow that continue to be monitored, particularly in shallow snowpack areas.
