Good morning, this is
Skies are mostly clear with mountain temperatures generally in the teens with some of the canyon bottom readings in the single digits which shows a slight temperature inversion. Northwest winds continue to average in the 30 mph range gusting into the 40s along the highest ridges but speeds are much slower along the mid elevation ridges.
Snow and Avalanche Discussion:
For a holiday weekend with nice weather, the backcountry was fairly quiet on Sunday. A couple of skiers found a few drifts that released on them with one skier getting pushed around a bit. The one thin minor wind slab was on a northwest facing slope at around 10,500 feet and the other more significant pocket was on a southeast facing aspect off of Mt Tuscarora at about the same elevation. The larger pocket cracked out about 50 feet wide. This might be interesting to look at say if you were in an avalanche class that just happened to be going on this weekend at the Wasatch Mountain Club.
When stability increases, so does our confidence in getting into more radical terrain. However, often the radical terrain is along the upper elevations and on the steepest slopes. These are just the places where we will have a chance to trigger a recent wind slab still today. Watch for these on numerous aspects in the higher terrain and use well placed slope cuts to test these. While these wind slabs can push a skier, snowboarder or snowshoer around, snowmobilers will hardly notice these when they release.
With the southerly facing and lower elevation terrain having already gone through a number of melt freeze cycles, today’s temperatures won’t be so outrageous to produce much wet activity but those slopes will most likely become damp.
Bottom Line for the
The avalanche danger is generally LOW. There are pockets with a MODERATE danger along the upper elevation ridgelines and in open bowls where a few new and old wind drifts could be triggered on steep slopes.
A ridge moves in today
and remains through Tuesday producing mild weather with mostly clear skies. Northwest winds will continue at their
current speeds through today before slowing into Tuesday. Temperatures will be near 30 at 8000 feet and
in the mid 20s along the upper ridges.
The Wasatch Powderbird Guides flew in Cascade and American Fork yesterday. The plan for today is to fly in American Fork and Cascade. They may use Grizzly Gulch or White Pine for a home run. For more detailed information please call (801) 742-2800 or go to their daily blog.
