Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Monday - January 12, 2015 - 6:59am
bottom line

Heightened avalanche conditions are developing and the danger will rise to MODERATE (level 2) at upper elevations in the backcountry. Accumulating snowfall and a breeze from the south will cause the danger of storm snow and soft wind slab avalanches to rise throughout the day.

  • You'll find generally manageable soft slab conditions, but small avalanches could run fast and far on a hard bed surface.
  • Evaluate the snow and terrain carefully.

current conditions

The 8400' Tony Grove Snotel reports 2 inches of new snow containing 0.3" of water. There's 57 inches of total snow containing 125% of average water for the date, and its 28 degrees this morning. A couple inches of fresh snow can do wonders for conditions, and a couple more will probably fall today. Expect to find a couple inches of fresh medium density snow on crust in most areas today... The new snow might have capped and preserved surface hoar that was widespread on the old snow surface and especially the shady protected areas.

Frost crystals or surface hoar formed on Monday's rime-crust at upper elevations in Steep Hollow. (1-9-2015)
recent activity

No avalanches reported locally since last week's natural wet activity.

description

Manageable fresh soft slabs consisting of new snow are possible in some upper elevation terrain, and more snow or wind than expected could create heightened avalanche conditions on some slopes. Soft wind slabs should be manageable, but even a small avalanche is likely go fast and far on a nice smooth hard bed surface. The danger will increase throughout the day, with increasing snowfall and light to moderate south winds.
weather

Expect snowfall, with 3 to 5 inches of accumulation, high temperatures around 31 degrees at 8500' and a moderate south wind. A couple more inches of accumulation is possible tonight, with temperatures dropping below 20 degrees and winds veering from the north-northwest. Expect clearing conditions tomorrow with temperatures in the mid twenties and a north wind. A high pressure system will rebuild over Utah midweek but shortwaves to the north will hopefully keep the inversion weak and give us in the far north a chance for some cloudiness and light snowfall. The next possibility of a more significant storm is about a week out.
