BUYTICKETSONLINE

Wise decisions come from experience. Experience comes from poor decisions. Join us in sharing experiences.

Inspired by the International Snow Safety Workshop (ISSW), USAW brings Utah’s snow and avalanche community together to share local knowledge and history and learn about emerging best practices. This professional development seminar taps into the vast avalanche knowledge we have in our own local avalanche community. You’ll hear about historic avalanche events and new innovations from avalanche forecasters, ski patrollers, snow scientists, UDOT avalanche professionals, search & rescue personnel, mountain guides, ski industry manufacturers, backcountry skiers & snowboarders, snowmobilers, avalanche scholars, and more. Click here to get the full schedule.


BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

The bottom line is to join us downtown tomorrow at 1pm for the Utah Snow and Avalanche Workshop. Find more info on our events calendar off the home page. See you there! Get your winter gear together and check out any number of avalanche courses offered by us and other providers off the education page.


CURRENT CONDITIONS

Skies are mostly clear and one begins to wonder if winter has already come and gone. By a little after 6am, Orion fades into the distant blue and purple to the west as one can just begin to distinguish light and dark thread. The strong southwesterly winds signal an approaching weather system that will run to the north and provide us with only clouds, cooler temps, and perhaps a trace or two. Yawn.

I suppose one could move on the snow above about 9500'. Iwent up into the Hidden Cirque above Primrose on Timpanogos a couple days ago and found 1-2' of windboard, faceted graupel, and variable melt freeze crusts.


THREAT #1

WHERE PROBABILITY SIZE TREND
No probability identified.
No size identified.
No trend identified.

Warm temperatures and time has perhaps slowed the weakening of the faceted snow in the last week or so. Brett went into upper Little Cottonwood yesterday and posted some thoughts and a Youtube video here. You'll find that we've been refining the website and the Current Conditions link now hosts all the most recent updates, to include snow profiles, photos, galleries, and Youtube videos, snow and avalanche observations from our professional observers, etc, etc. Enough information to push that dawn patrol back a few hours -


MOUNTAIN WEATHER

Weather systems passing to the north of us will give us the spillover trace or two Saturday into Sunday. We can expect cooler mountain temps in the 20's and light to moderate westerlies. A shortwave ridge builds in for late Sunday into Monday ahead of a large SPLITTER moving in from the northwest by mid-week. The trough looks to close off and perhaps benefit central and southern Utah, with little on the horizon after that. Stay tuned.
