Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Wednesday - December 3, 2014 - 6:49am
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. Fresh accumulations and drifting may cause the danger to rise during the day today. Evaluate the snow and terrain carefully, continue to use safe travel protocols, and practice regularly with your rescue equipment.

current conditions

With an inch of new snow this morning at the 8400' Tony Grove Snotel, it's 29 degrees and there's 38 inches of total snow containing 147% of average water for the date. The 9700' CSI Logan Peak weather station is recording south winds averaging around 20 mph. We're seeing fairly good stability locally. There's a few inches of powder capping a widespread solid crust from the pre-Thanksgiving rime and warmth. The coverage is quite good above around 8000', with the heavy snows from November nicely filling in the rocky terrain... There's around three feet of fairly dense snow and then the solid and mostly supportable crust. You can ride just about anywhere without sinking in too deeply, but we found ascending difficult because of the slippery crust.

We found good coverage but poor visibility in Steep Hollow on Monday

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 recent avalanches to report in the Logan Zone....

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

Although certainly not widespread, pockets with heightened avalanche conditions exist, and 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. There also 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.


We'll see snow today, with 2 to 4 inches of accumulation, high temperatures around 8500' of 34 degrees, and 10 to 20 mph west-southwest winds on the ridges. Snow will resume overnight, with another inch or so possible. Expect mostly cloudy conditions and continuing snow showers tomorrow, but again only an inch or so forecast. Looks like the sun may poke out of the clouds for a bit on Friday.
