The cooler temps have locked in the weak basal facets for the time being. Wind slabs still a concern on north aspects.

Summary

Confidence

Moderate -

Weather Forecast

Monday is forecast to be mostly cloudy skies with light winds out of the SW. Freezing levels will rise to 2250m during the day for Monday through Wednesday. Light flurries will develop Tuesday and leave us with 14cm by Wednesday night.

Avalanche Summary

No new avalanches.

Snowpack Summary

Valley bottom snow tends to be mostly refrozen snow up to 2300m, all aspects. Above that, the true north aspects have dry snow and crusts on the remaining aspects. Windslabs are still present in north facing alpine terrain. Expect conditions to change rapidly when the sun comes out.

Problems

Wind Slabs

These are lingering on true north aspects at the moment.

Watch for areas of hard wind slab in steep alpine features.

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood

Possible - Likely

Expected Size

1 - 2

Deep Persistent Slabs

This layer becomes a concern when the melt/freeze crust breaks down with solar radiation or warming.

Be aware of the potential for wide propagations due to the presence of hard windslabs.Be aware of the potential for full depth avalanches due to deeply buried weak layers.Be aware of thin areas that may propogate to deeper instabilites.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

2 - 3
