Points saillants

A MODERATE danger exists for triggering anavalanche that breaks 1-3' deep at the mid and upper elevation west through southeast facing terrain. A pockety Moderate danger exists on other steep slopes. Wet loose activity may be expected by late afternoon on steep southerly aspects.

Safe travel protocol is key: make a plan, communicate, one-at-a-time, keep eyes on your partner.

    The last two days of southerly winds and subsequent wind drifts are scattered across the steep terrain at the mid and upper elevations. Time and warm temps have helped a trend toward stability, but still give them a wide berth and allow them another day to become completely welded in. You'll find these drifts more prominently located in steep upper elevation west to north to east facing terrain.

    The mountain snowpack harbors more than a few structural irregularities and interfaces that involve old faceted October snow in the basement as well as pre-Christmas and post-New Year's buried weak layers. Time, warm temps, and settlement has helped the snowpack to adjust and slowly stabilize over the past few days, but I still need some more data points to feel completely confident. I would still advise approaching steep wind drifted areas - particularly thinner snowpack areas - with caution.

Special Announcement

We just released the first UAC podcast of the 2018/2019 season "Guilt". It's one of many short pieces (5 min) to mix in between our longer conversations.

Join the UAC, Greg Stump, and Scot Schmidt for the 30th Anniversary of Blizzard of Aahhh's at Brewvies on January 24. Scott Schmidt and Greg Stump will be signing posters and the MCs for an evening of big air, big hair, and lots of laughs.

No new avalanche activity was reported from the backcountry yesterday.

Snow and Weather

Greg Gagne's Most Excellent Week in Review is hot off the presses. Look for it in the Blog menu above or simply click here.

As of 4am, skies are mostly cloudy with light winds from the north. Mountain temps are in the mid 20s. A building and amplifying ridge of high pressure moves in from the west and we should start to see some clearing as the day wears on. Winds will continuing veering to the east and should remain light. A weak storm undercuts the ridge tomorrow but should only produce clouds for our La Sals and Abajos forecaster Eric Trenbeath and his mountain ranges to the south. The models are hinting at a more promising storm for mid-week.

Skiing and riding conditions are fair with pretty darn good coverage across the range, even at the lower elevations. Total snow depths are a settled 50-60" in the higher elevations. Many trailheads and lower elevation exits have snow depths from 35-45" (elevations roughly 6000'-7500').
