Special Announcements

My heart is heavy and it is with great sadness to report an avalanche accident involving a friend, colleague, and fellow avalanche professional. Craig Patterson, a highway avalanche forecaster, was tragically killed on Thursday in Big Cottonwood Canyon while investigating snowpack conditions. My thoughts, prayers, and energy go out to his friends and family. A report of the accident can be found here.

Weather and Snow

Skies are clear this morning and temperatures in the low 30's. West-southwest winds started ramping up early this morning and are currently blowing 20-30 mph along the high peaks and near the Skyline Summit. The rain/snow level has hovered right around 9,000', but a couple of storms this week laid down a fresh coat of paint and soft, settled powder can still be found on high elevation north facing slopes.

Here's the snowpack setup.

Recent Avalanches

Natural cornice fall near the Summit produced this shallow soft slab... otherwise it's been pretty quiet. Click here to view Steve and Darce's trip report from Seeley Canyon yesterday.

Avalanche Problem #1
Persistent Weak Layer
Type
Location
Likelihood
Size
Description

Increasing winds should find enough snow to blow around and form shallow wind drifts sensitive to the weight of a rider. Found on the leeward side of upper elevation ridges, today's fresh drifts will predictably break at or below you skis, board, or sled. Mostly manageable in size and depth, think about the consequences of triggering even a small slide, especially if you're in steep, unforgiving terrain.

Avalanche Problem #2
Cornice
Type
Location
Likelihood
Size
Description

Most cornices seem pretty welded in place, but these are unpredictable pieces of snow that have a tendency to break further back than you might expect. Rather than pulling on the dogs tail today to see how it's gonna react, it's probably best to avoid being on or near large overhanging cornices.

Additional Information

Today we can expect increasing clouds and southwest winds gusting into the 40's by late in the day as a fast moving cold front clips northern Utah. High temperatures climb into the mid 40's before diving into the low 20's overnight. A few inches of snow are expected out of this system before a short-lived break on Sunday and then cold, unsettled weather is slated for Monday through Wednesday. This could be a good snow producer for the region and a foot or so of new snow seems pretty reasonable.
