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

    These are improving. Sticking to well supported terrain will help stack your odds of not triggering it.

    This layer is back in the game. Thin spots and a weakening mid pack could spell trouble.

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.

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.
