Forecast for the Logan Area Mountains
Thursday morning, January 15, 2015
There is a MODERATE (level 2) danger in the backcountry. Solar warming will create heightened avalanche conditions on steep sunny slopes, and loose wet avalanches are possible with midday warmth. Triggered wind slabs remain possible in drifted upper elevation terrain.
- Evaluate the snow and terrain carefully.
- Avoid steep sunny slopes with wet snow,
- And wind deposits on steep slopes at upper elevations.
Special Announcements
Special thanks to Buttar's and ArcticCat for hooking us up with the light and powerful M8000. This machine will make our field days more fun, safe, and productive and will significantly boost our outreach and education efforts.
We picked up and tried out the new sled last week.
Weather and Snow
The 8400' Tony Grove Snotel reports 58 inches of total snow containing 119% of average water for the date, and its 26 degrees this morning. The central part of the Bear River Range picked up about 5 inches of moderate density snow from Monday's storm, and there's less at lower elevations. We found a bit more fresh snow (about 8 inches), and pretty good smooth, shallow powder riding conditions in Providence Canyon yesterday.
Recent Avalanches
We noticed a couple fresh natural wind slabs and some loose wet activity at upper elevations in the Tony Grove Area yesterday (1-14-15)
A fresh wind slab under the cliffs on the east side of Naomi Peak. (1-14-15)

Wet Snow
Description
Shallow wet sluffs consisting of saturated fresh snow are likely in steep sunny terrain. Wet slides should be manageable, but even a small avalanche is likely to pick up and involve all the new snow in it's path on a nice smooth and hard bed surface. Sunshine above the cloud-deck will cause the danger of wet avalanches to increase with midday solar warming.
Persistent Weak Layer
Description
We noted a good deal of drifting at upper elevations in the Tony Grove Area yesterday and a couple fresh natural avalanches. Triggered wind slab avalanches are possible on drifted upper elevation slopes again today. Wind slabs formed in exposed terrain at high elevations in and around terrain features like gullies, sub-ridges, and cliff bands. Drifts and wind slabs will be fairly obvious, consisting of stiffer snow, rounded, chalky looking, and perhaps hollow sounding. Best to avoid wind deposited snow on slopes steeper than about 30 degrees.
Additional Information
It'll be mostly cloudy again today down low, but sunshine above the clouds again is a good bet, with a high temperature at 8500' around 36 degrees.. Overnight low temperatures are expected to be around 24 degrees. It'll be mostly cloudy tomorrow with increasing west wind, high temperatures around 36 degrees, and a chance for snowfall, but accumulations look light at best.
