Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Friday - December 5, 2014 - 7:08am
bottom line

There's a LOW (level 1) danger and the snow is stable on most slopes in the Logan Zone. Exceptions and pockets of heightened or MODERATE (level 2) danger can be found on some drifted upper elevation slopes and in isolated or outlying areas with poor snow structure. Evaluate the snow and terrain carefully, continue to use safe travel protocols, and practice regularly with your rescue equipment.

current conditions

This morning at the 8400' Tony Grove Snotel, it's 32 degrees and there's 34 inches of total snow containing 140% of average water for the date. The 9700' CSI Logan Peak weather station is recording west winds averaging less than 10 mph. The coverage is quite good above around 8000', with the heavy snows from November nicely filling in the rocky terrain. You can ride just about anywhere without sinking in too deeply and you can see the larger protruding rocks, but I found ascending on skis difficult in places because of a slippery rime-crust beneath a few inches of mashed potato-like snow. Here's my Video Observation from the White's Bedground Area on Wednesday.

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!

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

Although certainly not widespread, pockets with heightened avalanche conditions exist, and triggered avalanches are possible in some upper elevation terrain. Avoid 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 strong winds. There may be very steep isolated slopes on the highest peaks where one could trigger a deeper persistent slab avalanche. The highest smooth slopes with snow cover in early November are suspect, but we've found a few shallower areas at upper elevations with weak sugary or faceted snow and a thin mid-pack weak layer consisting of small grained facets and graupel in some areas.


There's a chance of a few snow showers this morning, but the sun should come out this afternoon and high temperatures at 8500' are forecast to reach 36 degrees. Expect light southwest winds. We'll see a 20 % chance of snow tomorrow, mostly cloudy skies, a high temperature around 37 degrees and slightly increasing southwest winds.. Similar weather conditions will persist through most of next week, with only a hint of the next Pacific storm and a deep trough of Low Pressure at the extent of the forecast period and a week or so out....
