Avalanches: Non observed.
Weather: Partly Cloudy becoming overcast in the afternoon. Calm wind.
Snowpack: BTL: Very little snow. About 30cm HS on average. 2″ settled storm snow over facets or crusts.
NTL: Looked like the most continues snow coverage and deepest HS. If persistent slab structure is still intact, this looked like the most likely elevation to find that avalanche problem.
ATL: Snow coverage is mostly confined to gullies and wind loaded areas. Looked very “continental” with generally very little snow coverage.
Phone book style wind slab resting over facets with natural crack running through convexity. HS about 50cm in deepest part of the wind loaded feature. South aspect at 12,000ft

Date: 12/19/2015
A the high pressure ridge axis moves east of us today, we will see warm southwest flow ahead of the first in a series of Pacific waves. Mountain temperatures will climb into the 30’s above valley inversions today with clear skies. Tomorrow, a poorly organized cold front swings in from the northwest, bringing showery snowfall beginning midday. Accumulations should be less than a few inches by sunset. Unsettled weather continues early next week before a more powerful system arrives Tuesday into Wednesday. Details to come.

Elevation: 11,000
Avalanches: See crown profile. Investigated the crown of a unintentional skier triggered slide that occurred earlier in the day. Skier was initially caught but not carried. SS-ASu-R1-D1-O. The avalanche broke on a layer of fist hard facets below 12/11 melt freeze crust. It was on a slightly cross loaded feature, with crown height ranging from 35cm to 20 cm. Approximately 75 feet wide and 200 vertical feet.
Weather: Light snow transport from light to moderate NW winds. Scattered to broken skies. Mild temps.
Snowpack: See profile.

High pressure is rebuilding over Colorado, bringing clear skies and rebounding temperatures through Saturday. Temps have already risen 10 degrees overnight in town, and we should see them reach the mid to upper 20’s today in the mountains and into the 30’s tomorrow under warm air advection. A series of Pacific waves will begin to impact our region beginning late Saturday night. Sunday’s system looks poorly organized, but it will signal the start of a snowy week.
