Highlights

Today, there is a MODERATE avalanche danger for triggering an avalanche failing into the buried facets on upper elevation northwest-north-east facing aspects. There is a LOW avalanche danger on all other aspects and elevations, where you may trigger a shallow wind-drifted snow avalanche. Special attention should be given to recently wind loaded steep slopes that harbor faceted snow near the ground. Areas where you may trigger an avalanche 1'-3' deep will be thinner rockier zones and areas that avalanched earlier this season and have been re-loaded with more wind and snow.

These shallow wind drifts will be easy to spot as they will be pillowy, rounded, and located on the windward side of ridgelines and terrain features. Shooting cracks are signs of wind drifting and you may see more of this today. Cornices point to where the snow is loading on the slopes and caution is advised before jumping onto or traveling underneath any wind loaded slope.

Visiting UAC Moab Forecaster Eric Trenbeath submitted an observation from Cutler yesterday where he found shallow sensitive wind drifts in mid elevation north-east facing terrain.

This layer of weak facets is no longer giving us obvious signs that it is going to avalanche. The cracking, collapsing, and whumpfing has subsided and the lack of in-your-face weakness makes for a tricky problem. Most likely areas to trigger an avalanche 1'-3' deep and up to 100' wide are thin rocky areas, gully features, and locations that have avalanched earlier this season.

Special Announcement

Join the UAC at Deer Valley on January 30th for the 2nd Annual Blizzard Ball Gala. Former Director of the Utah Avalanche Center, Bruce Tremper will deliver the keynote address.

Recent Activity

Yesterday, we had no reports of avalanches from backcountry travelers. There were a couple of reports from Cutler Ridge discussing shallow drifts of new snow HERE and HERE. Read all observations HERE.

Snow and Weather

Currently under partly cloudy skies trailhead temperatures are in the low single digits °F, while the highest peaks are well below 0°F, with some readings as low as -8°F. Winds are blowing lightly from the northeast at the lower elevations and blowing from the north-northeast in the mid 20's gusting to the 30's at the highest ridgelines. Wind Chill is -36°F on the highest peaks, where any exposed skin can frostbite in under 10 minutes. Just to our north Peter Sinks, which is typically one of the colder locations in the Lower 48 is currently -23 °F. Today, we should see sunny skies. Temperatures will rise to 10-16 °F and winds will blow lightly at the lower elevations from the northeast and from the north 25 gusting to 35 MPH at the highest elevations. With a northeast aspect to the winds there could be areas that see wind gusts up to 45 MPH. No new snow is expected today. There was a trace of snow overnight, settled snow depths throughout the forecast region are 24"-50" and the cold temperatures have kept the snow surface soft. There is great travel to be had on 4"-8" of settled snow and the lower angle slopes (where you aren't feeling the crust) are still holding soft turns.
