More cold starts this week, but atleast the ski quality is still good in sheltered treeline areas.

Weather Forecast

Another cold night coming our way. We will be in the -30 ballpark by early morning. No wind is forecasted, atleast the windchill won't make it worse. And of course, no snow when its this cold. There is a warm light at the end of the tunnel. Wednesday's high is -5.

Avalanche Summary

Two sz2 slabs were noted in the Goat Range today. Above 2400m, and east aspects.

Snowpack Summary

More cold weather...needless to say the snow pack as a whole is faceting as we speak and becoming weaker. This may not be all bad. The alpine still looks loaded with recent avalanches being up to a meter deep within the wind slabs. Treeline windslabs are starting to weaken which will decrease their "touchiness". How fast that happens depends on the density of the slab. At the moment there are still pockets of harder slabs in wind prone areas. No wind transport today. Below treeline is occasionally supportive where there's been wind and traffic, but in low elevation trees expect to wallow or walk on the ground...or both.

Problems

Wind Slabs

An icon showing Wind Slabs
These are improving. Sticking to well supported terrain will help stack your odds of not triggering it.
Avoid travelling in areas that have been reverse loaded by winds.Caution in lee and cross-loaded terrain near ridge crests.

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

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

1 - 2

Deep Persistent Slabs

An icon showing Deep Persistent Slabs
This layer is back in the game. Thin spots and a weakening mid pack could spell trouble.
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

Unlikely - Possible

Expected Size

1.5 - 3
