In sintesi

The overall danger is LOW and human-triggered avalanches are unlikely. Small avalanches remain possible in isolated areas or extreme terrain.

As the heatwave continues, expect an increasing likelihood for small, loose wet avalanches, especially if we see any sunshine today. Pay attention to the snow surface and avoid steep slopes that are becoming wet and sloppy.

Special Announcement

Check out the latest edition of the UAC podcast with Moab forecaster Dave Garcia where he talks about the challenges of forecasting for our remote and isolated range with limited information.

Urgent battery replacement required for anyone who received batteries from one of our participating "Batteries for Beacons" shops. Please review the "Batteries for Beacons" replacement notice on our blog. Batteries distributed through our "Batteries for Beacons" program this year have shown to be inadequate length.

Geyser Pass Road: Surface is mainly snowpacked and icy above and bare dirt down low. AWD with good tires recommended.

Grooming Conditions: Trails have not been groomed since Wednesday.

A huge shout out to this great crew who turned out to improve their avalanche awareness and rescue skills at our Backcountry 101 course this weekend!

Winds on Pre-Laurel Peak: SW 20-25 Temp: 40° F Percent of Normal (SWE): 72%

Weather

Southwest winds continue their 48 hour rein of terror and it's a sweltering 40°F up there this morning at 10,000'. Up on Pre Laurel Peak at 11,400' temperatures are just below freezing. Today will be a few days warmer than yesterday with continued breezy conditions and lingering high clouds. Things start to cool off slightly on Wednesday. An active pattern resumes later in the week but as has been the case for the majority of this season, most of the action will be to the north.

General Conditions

Sustained southwest winds and very warm temperatures make me think of a hairdryer being turned on to our meager snowpack. Snow is disappearing quickly from southerly aspects and many are bare. Above treeline, northerly aspects aren't much better after a barrage of north wind events in mid-January. Near treeline and below the snowpack is thin, variable, and largely faceted through.

Very warm temperatures and a lack of an overnight re-freeze are increasing the likelihood for loose, wet avalanches. I've got some uncertainty about this, but as the surface snow becomes damp and cohesive, it will develop a propensity to slide off looser, cohesionless snow underneath. This is generally a solar side of the compass concern but many of those slopes are bare or very thin so I think the threat is overall quite limited. However, due to the extremely warm temperatures, and underlying poor snowpack structure, we may also experience some wet activity on polar aspects below treeline. Best practice is to avoid steep slopes that are wet and sloppy.

South facing slopes are going fast (photo above), while northerly aspects above treeline are faring only slightly better (photo below).
