Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Friday - December 12, 2014 - 7:09am
bottom line

There's a MODERATE (level 2) danger on drifted slopes at upper elevations. Heightened avalanche conditions exist and you could trigger wind slab avalanches in some areas. Avoid drifted upper elevation slopes. Evaluate the snow and terrain carefully, and check, carry, and practice regularly with your rescue equipment.

Expect a rising danger, with increasing wind and some accumulation as we head into the weekend.

current conditions

The CSI Logan Peak weather station is currently reading south winds averaging over 30 mph, with 60 mph gusts, and it's 35 degrees at 9700'. Last night the 8400' Tony Grove Snotel reported 33 inches of total snow containing 108% of average water for the date. High pressure conditions have taken toll on the snow at upper elevation, weakening the snow on the surface and turning the entire snowpack to sugary non-cohesive facets in shallow areas. We're still finding good coverage at upper elevations, but the snow is less supportable around rocks and caution is certainly required, given the shallow early season conditions........The Tony Grove road is not maintained for wheeled travel in the winter!

A view of Cherry Peak in the Mount Naomi Wilderness from the east is showing pretty good coverage up high. (12-10-2014)

Go to our Video Observation from Upper Bullen Basin on 12-10-2014..........HERE

Everyone needs to carry a shovel, probe, and transceiver. Be sure your rescue gear is functioning by practicing with it, and when polite invitations don't work, force your partners to join in the fun. You can bury your pack with your transceiver in it and have your partner find, probe, and excavate it. Then get them to do the same for you. Training your team is critical in this game.

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

Freshly formed wind slabs could be rather stiff, or even hard, and they could allow you to get out on them before releasing. Avoid drifts and wind slabs at upper elevations. These should be fairly easy to recognize; chalky looking, hollow sounding, stiffer or even supportable snow. Increasing winds today and some accumulation tonight will cause increasing danger as we head into the weekend.


It'll be partly cloudy and windy today in the mountains, with high temperatures pushing 50 degrees again at 8500' and strong south winds. A splitting storm will hopefully bring some snow to upper elevation terrain tonight and Saturday, but accumulations in our area don't look to be all that substantial.... Expect 2 to 4 inches of accumulation overnight and another 1 to 3 tomorrow, with westerly winds...
