Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Tuesday - December 3, 2013 - 6:56am
bottom line

Heightened avalanche conditions exist and there's a MODERATE (or level 2) danger on drifted slopes at upper and mid-elevations. You could trigger wind slab avalanches in steep drifted terrain. Dangerous conditions and pockets of CONSIDERABLE (level 3) danger may exist in some upper elevation areas with substantial deposits of drifted new snow. Being caught and carried in even a small avalanche could be very dangerous due to rocks in the runout. Very shallow and rocky early season snow conditions exist across the Logan Zone. Evaluate the snow and terrain carefully.

current conditions

The Tony Grove Snotel at 8400' reports 3410 ths of an inch of water in the past 24 hours, and a couple more inches of fresh snow. At 3:00 AM, it's 15 degrees this morning, and there is 18 inches of total snow containing 76% of average water equivalent for the date. The 9700' Logan Peak weather station reports 2 degrees and northwest wind averaging a bit under 20 mph. The remote weather station at the top of Beaver Mountain reports 7 inches of new snow in the last 24 hours. The Tony Grove Road is not maintained for wheeled travel in the winter, and the road is currently very icy and treacherous in places. 4-wheel-drive vehicles and chains are recommended. It's important to check and continue practicing with your avalanche rescue equipment.

recent activity

No avalanches were reported recently in the Logan Area, but yesterday we triggered an audible collapse or a "whumpf", in drifted upper elevation terrain west of Tony Grove Lake. This is a sure sign indicating an unstable snow structure.

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

You'll find fresh drifts and sensitive wind slabs today, mainly in exposed upper elevation terrain. Slabs are building on preexisting very weak sugary or faceted snow, which is widespread at upper elevations after the prolonged Thanksgiving high pressure system. Avoid drifted snow on steep slopes today. Dangerous avalanche conditions may exist in some areas with substantial deposits of fresh snow, especially in drifted terrain.
