11th Annual Utah Snow & Avalanche Workshop Open and Motorized Sessions Oct. 27th.

Advisory for the Salt Lake Area Mountains

Issued by Drew Hardesty for Saturday, February 3, 2018 - 5:25am

Most terrain has a LOW avalanche danger. Isolated areas of MODERATE danger, however, exist on northwest to east facing slopes above about 9000'. In this terrain, human triggered avalanches 1-3' deep are possible. Additionally, shallow pockets of soft and hard wind slab are littered across the landscape, but most problematic in high consequence terrain. Lastly, damp push-alanches are possible in steep low to mid-elevation sheltered slopes that have remained warm for the past several days.

The latest UAC podcast - "Recreating Like a Pro - A Conversation with IFMGA guide Anna Keeling" is live. This podcast will be ideal for anyone looking to pick up some tips and tricks from a professional mountain guide for recreating in the winter backcountry environment.

Weather and Snow

By and large, we'll be under a moderate to strong northwesterly flow for the rest of time eternal. Ok at least for the next week. Expect maybe a trace to an inch of snow this weekend with perhaps 2-5" on Monday/Tuesday. The Logan and Ogden mountains may see twice that. For today, we'll have overcast skies, west-northwest winds blowing 35+mph and temps in the upper 20s along the ridgelines.


I've cherry picked one of the weather models for expected total precipitation (in SWE - Snow Water Equivalent) through next Friday. As you can see, we're clearly on the dry side of the storm track while our neighbors to the north in Idaho, Wyoming and Montana eat our lunch. Road trip anyone?

Recent Avalanches

None. See Greg's Week in Review for more info.

Description

I was able to collapse and crack out a small test slope yesterday on a north facing piece of terrain at 9200'. It cracked out about 1' deep and 20' across. It wasn't particularly representative of most of our terrain and yet there it was: poor structure, additional wind loading, trigger. Collapse. The moderate to strong winds will add just a bit of extra stress to areas of poor structure. Our lingering persistent slab avalanche problem exists at elevations 9000' and above, on slopes facing northwest through east (with a particular emphasis on north through northeast.) Thinner snowpack areas are particularly suspect – such as rocky rollovers as well as terrain outside of the upper Cottonwoods.
