Kernpunkte

Slopes at upper elevations that face N and NE are the ones that potentially harbor faceted layers that could produce avalanches today. If winds begin transporting and drifting snow this afternoon onto northerly facing slopes, the danger could increase. The avalanche danger is MODERATE on all upper elevation northerly and east facing slope. All other slopes have a LOW avalanche danger.

    The Ogden area mountains had minimal old snow on the ground prior to Thanksgiving. A few areas at upper elevations have this old snow on N and NE aspects. Greg and the Snowbasin snow safety team found some faceting in the snow that fell on Thanksgiving day (see photo below). The load of today's new snow will test this potential weak layer, but I'm unsure how it will react. Look for natural avalanches, look for collapsing or cracking, and use small test slopes to see how this layer of Thanksgiving snow or isolated pockets of October snow reacts. Also, perform several stability tests. In the long run, today's warm, dense snow will help heal any weaknesses in the snowpack. For today, I wouldn't trust it too much.

    Watch for drifting snow this afternoon when winds increase from the S and SW and possible form shallow wind slabs. The additional weight of these wind slabs could also cause avalanches to break deeper on some of the older snow layers from October or Thanksgiving day.

Snow and Weather

Since yesterday 5-7 inches of snow (0.4-0.8" of water) fell near Snowbasin. 8-10 inches of snow (1" of water) fell near Ben Lomond and Monte Cristo Peaks.

Winds blew a bit stronger overnight but were generally light this morning at 5-10 mph from the WSW with some gusts 15-20 mph.

Temperatures this morning are near 30 degrees F at trailhead elevations and in the low 20s F near 9000 feet.

The snowpack is slowly building.

  • Near Snowbasin at 8000 feet, it is 20-30 inches deep.
  • On Ben Lomond it is 12-18 inches deep.
  • At Monte Cristo at 8900 feet, it is 22 inches deep.

Today will have a lull in snowfall with more coming this afternoon when winds will increase and blow from the S and SW at 20-30 mph with higher gusts.
