Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Monday - December 1, 2014 - 7:05am
bottom line

There's a MODERATE (level 2) danger on some drifted upper elevation slopes in the backcountry. You could trigger fresh wind slabs in areas that picked up 6 or more inches of fresh snow yesterday and overnight. Heightened avalanche conditions also exist on isolated slopes at upper elevation with poor snow structure. There's a LOW (level 1) danger and the snow is stable on most other slopes in the Logan Zone. Evaluate the snow and terrain carefully, continue to use safe travel protocols, and practice regularly with your rescue equipment.

special announcement

We look forward to seeing you at our annual fundraiser party at the Italian Place in Logan on Wednesday evening, December 3... We very much need and value your support.

current conditions

With a couple inches of new snow this morning at the 8400' Tony Grove Snotel, it's 28 degrees and there's 36 inches of total snow containing 148% of average water for the date. The 9700' CSI Logan Peak weather station is recording southwesterly winds averaging in the mid teens. We're seeing fairly good stability locally. Looks like some shallow powder or dust-on-crust conditions, with a bit more new snow in the Southern Bear River Range.

Be sure your rescue gear is functioning by practicing with it, and force your partners to join in. It is they who will be your best bet for survival if you get caught in an avalanche. The Tony Grove road is not maintained for wheeled travel in the winter!

recent activity

No avalanches were recently reported in the Logan Zone, but it's still dangerous on upper elevation north through east facing slopes in the Central Wasatch Range.

Avalanche Problem 1
type aspect/elevation characteristics
over the next 24 hours

Triggered wind slab avalanches are possible in exposed upper elevation terrain. Avoid recent deposits of drifted snow on the lee side of major ridges and areas where snow has been deposited into gullies or below cliff bands by the recent strong winds. Heightened wind slab conditions exist in areas that received a bit more snowfall and the fresh snow was drifted onto steep slopes. There also may be very steep isolated slopes on the highest peaks where one could trigger a deeper persistent slab avalanche. Slopes with snow cover in early November are certainly suspect, but we've also found weak sugary snow from the surface on around 11/20 (between first and second storm), with the slab from just before Thanksgiving propagating in tests.


Expect mostly cloudy skies and a 40% chance of snow, with high temperatures at 8500' around 32 degrees and a moderate southwest wind. It'll be mostly cloudy again tonight, with west winds and a low of around 26 degrees. Another round of light snow will develop late Tuesday and Wednesday.
