In sintesi

Today, MODERATE avalanche danger exists on upper elevation slopes with an easterly component where human triggered, wind drifted avalanches are POSSIBLE failing up to one foot deep. Sitting atop a variety of old snow surfaces, including facets, today's drifts will be reactive to our additional weight as a rider and may break out wider than you might expect.

For today, if you lose the wind you lose the problem. The best riding is met with reduced avalanche danger and can be found in upper elevation terrain, out of the windzone, on protected, northerly facing slopes.

    In the photo above, the red arrows indicate the windward side of a ridge where the wind scours and strips snow from. The purple arrows indicate the leeward side of the ridge, where the snow is loaded on and you are most likely to find wind slabs and today's avalanche hazard.

    Formed on a variety of snow surfaces, including faceted snow, today's wind drifts will be reactive to the additional weight of a rider and found on upper elevations slopes with an easterly component. Since Friday afternoon, the range has received 3-7" of light-density snow accompanied by light to moderate winds blowing 20-30MPH from the west. Todays wind slabs will be bigger than yesterdays, and remember, even a small slide in consequential terrain could seriously mess us up by straining us through rocks, cliffs or trees.

    Fortunately, we can see and steer clear of this problem today. Look for and avoid fat, rounded pillows of snow on the leeward sides of ridges, gully's, and cut banks that look textured or different than the surrounding snow. Throughout your travels stomp around on test slopes and get a feel for how things are bonding to the old snow surface before getting into committed, exposed terrain and finding out the hard way.

    Above is an example of a leeward slope that has been previously wind loaded and has all the right visual warning signs to observe.

Recent Activity

Yesterday, no major activity was reported from across the range, but Andy P and Sean C noted small loose snow avalanches in steep and technical terrain. You can learn more about their take on the snowpack and their travels, here.

It's not always the size of the avalanche that matters, even a small sluff can be hazardous if triggered in consequential terrain, like in the photo above.

Snow and Weather

Nowcast - Since Friday, we have received 3-7" of light density snow snow favoring the North Slope and Central Wilderness. Temperatures have been frigid, but under clear skies we are slightly warmer this morning with temperatures in the single digits from trailheads all the way up to the high peaks. Unfortunately, winds blowing from the west in the 20's gusting into the 30's drop the windchill to nearly -15°F, keeps it crispy out there through the morning.

Forecast - Clear skies are on tap for today and it should be a gorgeous winter day. Expect temperatures to warm slightly, with a high of 20°F, but you may not feel it as the westerly winds continue to blow in the 20 to 30MPH range keeping things feeling chilly.

Futurecast - A quick break in things early this week is followed by a mid-week pulse that could potentially deliver additional snowfall to the range.

Travel Conditions -Since Friday we received 3-7" of snow across the range favoring the North Slope. Settled snow depths are 1-4' across the range, and very elevation dependent. On the north half of the compass, fresh snow on top of old, faceted, recycled powder has proven to be some of the best riding of the season! On the solars, a few inches has helped to cover up any variable old crusts creating fantastic travel conditions.

It sure is amazing what a few inches can do for moral. Conditions on the South Slope near the West Fork significantly improved over the past few days, and even the riding on solar aspects was manageable and pleasant.
