In sintesi

In most areas, the avalanche danger is LOW. Pockets of MODERATE danger exist on some outlying upper-elevation north- through southeast-facing slopes, where human-triggered avalanches of wind-drifted snow up to 1 foot deep are possible.

It is possible to trigger small avalanches of wind-drifted snow where wind slabs formed by redeposition on preexisting weak surface snow consisting of near-surface facets or surface hoar in exposed upper-elevation terrain.

Avoid and stay out from under stiffer pockets of recently drifted snow on steep slopes.

Wind slabs may have formed or been cross-loaded in and around terrain features such as mid-slope roll-overs, gullies, under cliff bands, or sub-ridges.

Suspect wind slabs are often chalky, rounded, and smooth, and they can sound hollow, like a drum. Shooting cracks and whumpfs or collapsing indicate instability.

A layer of surface hoar and small near-surface facets is now capped, buried shallowly, and preserved by fresh snow; this will likely become a problematic, persistent weak layer. Drifts of new snow forming on this layer of preexisting weak surface snow could break under the weight of a skier or rider.

Snow and Weather

The few inches of new snow from Wednesday really improved (it's all relative) riding conditions. While you can feel and see old tracks and buried obstacles, soft snow still exists in shaded, sheltered upper and mid-elevation terrain. The new snow sits atop a faceting snowpack and will quickly facet during the upcoming period of prolonged high pressure. Read my essay linked above to understand what we, as avalanche forecasters, think about as the weather remains stagnant. On exposed slopes, you'll find a wide variety of surfaces from breakable wind or melt-freeze crusts to wind buff, where the snow has been stripped away.

This morning at the UAC Card Canyon weather station at 8700 feet, it's 25°F, and there is 42 inches of total snow. The Tony Grove Snotel at 8400 feet reports 30°F and 55 inches of total snow. On Logan Peak at 9700 feet, winds are blowing in the 20s mph from the west, gusting into the 30s mph. It's 21°F on Paris Peak at 9500 feet, and the wind is blowing 27 mph from the west-southwest, gusting to 37 mph. Over the past few days, moderate winds may have created pockets of wind-drifted snow resting on weak, sugary facets in the most exposed terrain.

Skies will be mostly sunny today with 8500' highs near 38°F. Light winds will blow from the west. Same same for the rest of the week with increasingly warmer temperatures each day.

Yesterday, we encountered hard, wind-textured snow in exposed upper-elevation terrain, a sign that pockets of wind-drifted snow may be resting on weaker, faceted snow in lee areas.

Additional Info

***Travel with a partner, and cross or ride slopes steeper than 30 degrees one at a time while the rest of your group watches from a safe spot.

Ensure that everyone in the group has avalanche rescue equipment (a transceiver, probe, and shovel) and knows how to use it. Now is a great time to get out in the mountains, explore new terrain, and practice companion rescue with your backcountry partners.
