In sintesi

The potential exists for humans to trigger dense slabs in steep terrain at the mid and upper elevations. Yesterday a snowboarder triggered a 28 inch deep hard slab avalanche on a south aspect of Prater Mountain at an elevation of 9,000 feet. On Saturday a skier triggered a two foot deep hard slab avalanche on a northwest aspect of Dry Creek Mountain near Alpine. A video of a snowmachiner who was recently caught and partially buried in a large slide west of the Poison Meadows warming hut can be viewed at https://www.youtube.com/watch?feature=player_embedded&v=aGUQC5k3dFM. Similar events are possible today. Wet slides are possible at the lower elevations on very steep slopes in areas where rain falls upon isothermal snow.

    At the mid and upper elevations skiers and riders could trigger dense surface slabs up to two feet in depth. These slabs lie upon crusts that formed in late January and are unstable on steep slopes where faceted snow lies upon those crusts. New snow accumulations will increase the load on areas of unstable snow and increase the potential for these slabs to be triggered by humans.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )With mostly clear skies overhead temperatures should drop into the 20s before the next storm system begins to spread valley rain and mountain snow into the region tomorrow morning. A fast moving low pressure trough will bring periods of heavy snowfall to the higher elevations during the day. New snow accumulations could exceed six inches at 10,000 feet by sunset. Periods of lighter snowfall are likely into the night. West-southwest winds at 15 with gusts to 25 to 30 miles per hour will accompany the snow. Temperatures will rise into the 30s. The general avalanche hazard is expected to be MODERATE. Dense surface slabs six inches to two feet in depth could be human triggered in very steep terrain at the mid and upper elevations. Wet slides are possible at the lower elevations on very steep slopes where rain falls upon an isothermal snowpack.
