Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Sunday - April 6, 2014 - 7:01am
bottom line

Mostly stable conditions exist, avalanches are generally unlikely, and there's a LOW or level 1 danger in the backcountry this morning. Even so, triggered cornice falls and wind slab avalanches are possible on drifted upper elevation slopes. Sun and warming will create heightened conditions and the danger will rise to MODERATE or level 2 this afternoon. Wet avalanches will be possible during the warmth of midday. Evaluate the snow and terrain carefully.

description
  • You could trigger shallow wind slab avalanches in some steep drifted terrain today. Avoid stiffer, recently drifted fresh snow in steep lee terrain and in and around terrain features like gully walls, outcroppings, or under cliffs.
  • Avoid and stay out from under large and overhanging cornices along major ridge-lines, which are likely to break further back than you expect and could trigger avalanches on slopes below. It's especially important to stay out from under these guys when they are forming with drifting and during the heat of the day, when some may naturally fail and calve off in large chunks.

weather

We'll see some snow in the mountains today, with increasing west winds and 8500' high temperatures pushing 33 degrees. 1 to 3 inches of accumulation is possible by evening. Snow showers are possible tonight, with low temperatures around 25 degrees and decreasing wind. Much warmer temperatures and lots of sunshine are expected in the next few days, with 41 degrees the high at 8500' tomorrow, and 51 degrees forecast for Tuesday. We will be monitoring this significant warm-up and expect an increasing avalanche danger in the backcountry.
