Good morning, this is
Storm totals from the last 24 hours are only a trace to around 3 inches of new snow which mostly fell early Tuesday. Northwest winds were gusty getting into the mid and lower portions of the drainages somewhat but tapered off late in the afternoon. Temperatures stayed cool with mostly cloudy skies and are currently in the single digits to low teens.
Snow and Avalanche Discussion:
The northwest winds on Tuesday were transporting the new snow erasing old tracks and forming some drifts up to 2 feet deep. These drifts were not very sensitive for the most part only cracking after much provoking. In general, I expected to see more wind damage then I found. Under the newest snow, southerly slopes have a moderately thick melt freeze crust while northerly slopes have settled powder. I did not note any significant weakness in the upper portion of the snowpack aside from the fresh drifts.
For today, the drifts that formed Tuesday will be our main focus. It doesn’t seem like they’ll pose much problem but if you’re along the upper elevation ridges keep them in mind. If you find one that pops out it will most likely be a pocket and not entrain much snow. It could be enough to knock you down or take you for a ride though if you’re snowshoeing, skiing or snowboarding. Snowmobilers will hardly be affected by these pockets. You’ll find these mainly on easterly facing slopes but as usual watch for cross loading on all aspects.
Bottom Line for the
The avalanche danger is generally LOW however there are pockets with a MODERATE danger along the upper elevation ridges that have recent wind drifts on them. These are mostly on easterly facing slopes but always watch for crossloading on all aspects. Keep in mind that with lower avalanche danger ratings we tend to push ourselves into more complex terrain which is just the place we’re most likely to find one of these pockets today.
We’ll see some clouds over the mountains today with the chance of a snow flurry. Temperatures will remain fairly cold with highs in the mid to upper 20s at 8000 feet and low 20s along the upper ridges. Northerly winds will be in the 5 to 15 mph range gusting into the 30s and 40s along the more exposed locations. High pressure gradually moves in over the next few days with slowly warming temperatures. The next chance for snow looks like it will be this weekend.
The Wasatch Powderbird Guides did not fly on Tuesday. Weather permitting today they’ll have two aircraft in the Try Canyons operating in Mineral, Cardiff, Days, Silver, Grizzly, White Pine, and Mill Creek. For more detailed information please call (801) 742-2800 or go to their daily blog.
