Forecast for the Logan Area Mountains

Issued by Toby Weed for Tuesday, December 5, 2017 - 7:09am

Heightened avalanche conditions exist on upper and mid elevation slopes in the backcountry. Pockets with more dangerous conditions and a CONSIDERABLE danger might be found in exposed upper elevation terrain. Human triggered persistent and wind slab avalanches are possible. Evaluate snow and terrain carefully. Avoid steep drifted slopes at upper elevations.

  • Fast moving and long-running avalanches are possible on smooth and very hard underlying snow.
  • A ride in even a small avalanche could be particularly dangerous due to the hard underlying snow and potential for being raked through rocks or deadfall below.

Weather and Snow

The Tony Grove Snotel at 8400' reports 10°F and 38" of total snow containing 121% of average SWE (Snow Water Equivalent). The site recorded 27" of new light snow morning, and we found nice deep powder conditions up at Beaver Mt all day. It's 6°F at 9700' at the CSI Logan Peak weather station, with northwest wind currently blowing 6 mph.

Just beneath the fresh powder, shallow early season snow conditions exist, and hitting rocks or stumps is a significant hazard. Travel cautiously and keep your speed down. The Tony Grove Road is not maintained for wheeled travel in the winter.

Avalanche Problem #1
New Snow

Record warmth around Thanksgiving melted a good deal of snow across the zone, and a solid refreeze last week turned the remaining snow rock hard. A couple brush-by storms deposited an inch or two of snow and this is now weak. In some areas, yesterday's snow may not bond well to the hard Thanksgiving snow surface especially on slopes where yesterday's surface snow is weak, faceted and in some areas capped with surface hoar of frost. Persistent slab avalanches could be fairly wide and might run fast and far on the slick underlying snow.

The snow surface at upper elevations Saturday was sparkling with widespread feathery surface hoar or frost crystals. Surface hoar often becomes a tricky persistent weak layer once buried. (Jensen, 12/2/17)

Avalanche Problem #2
Wind Drifted Snow

Monday's light powder snow will easily be drifted into stiffer wind slabs in exposed terrain. Avoid fresh drifts near ridges and in and around terrain features like gullies, rock bands and sub-ridges.

Additional Information

Strong high pressure centered to the west of Utah will maintain a stable northerly flow across the Great Basin through the end of the week.
