In sintesi

The danger for wet avalanches will rapidly rise to CONSIDERABLE on all steep east to south to west facing aspects this morning. With direct sun and skyrocketing temperatures, dangerous wet avalanche conditions can be expected on and below steep solar terrain. Mid and lower elevation shady terrain will also produce wet slides and a MODERATE danger with today's heat.

Cornices, roof avalanches and glide avalanches are all objective hazards for today.

Wet Avalanches: MUCH warmer temperatures overnight and this morning will result in a much narrower window to recreate on and below all steep solar aspects and some mid/low elevation polar aspects today. Early starts are key and you'll probably want to be off of this terrain by mid-to late morning. Pay attention to the crusts and snow under your feet or ride. Roller balls, dripping water off of rocks, and your boots or skis sinking into the surface snow are signs it's time to move to lower angle terrain or head to the car.

Beyond this window, skyrocketing temps and direct sun will lead to unstable and dangerous wet avalanche conditions. Natural and human triggered avalanches are expected.

Cornices: Avoid traveling on or underneath large cornices, as they may become sensitive to heating and collapse naturally onto the slope below.

Roof Avalanches: With warming temperatures and a lot of cold snow available, roof slides are a concern. Be aware of adults working solo outside or children playing, as these are the people most susceptible to roof slides.

Recent Activity

Wet avalanches: With skyrocketing temperatures and direct sun, wet avalanches cascaded down the steepest sunlit terrain yesterday, leaving impressive debris piles. Those overstaying their welcome on these sunlit slopes by midday also found it easy to trigger wet loose avalanches and it paid off to move out of the fall line to avoid the cement mixer. There was even a close call in the Y Couloir in LCC yesterday; the Y "presents" as north facing but the upper reaches catch some early sun that can trigger dry or wet sluffs.

Soft slabs: A few soft slab avalanches occurred in steep alpine terrain. One - unknown trigger - on steep southeast facing Tuscarora at 10,500' (pic 1); the other possibly high off the Cardiac Ridge (pic 2). Most of these lingering soft slabs will have healed overnight.

⚠️ Thanks to those who have called Alta Central or the local ski area dispatch to report avalanches in areas adjacent to ski areas or above the road. This prevents SAR teams from unnecessarily responding in potentially dangerous situations for no reason. MORE INFO

Snow and Weather

Skies are clear.

Winds are light from the northwest, blowing 5-10mph on all but the highest peaks, where they're blowing 15-20mph.

Mountain temperatures are 10-15°F warmer than they were at this time yesterday with current overnight "lows" in the upper 20s to low 30s. I do expect a refreeze of the snow, but it'll be fleeting with a shorter window to recreate on and below steep solar aspects today. Beyond that window, the snow will become wet, punchy, unsupportable and dangerous for wet avalanches.

All aspects and elevations but high true north will have varying degrees of supportable to breakable to trapdoor crust this morning.

For today, we'll have sunny skies, light winds backing to the southwest, and mountain temperatures skyrocketing to the low 50s down low, the mid to upper 30s up high.

The Outlook: Winds will start to increase from the southwest tonight and Thursday ahead of a fairly potent looking storm arriving Friday. Relief in the form of a cold front arrives early afternoon Friday with snowfall expected through the weekend with 10-16" expected.
