Highlights

Triggering a large avalanche 2-3 feet deep is possible today. The danger is highest on shady slopes above 8000 feet where weak, sugary snow remains preserved and buried.  Snow and wind will continue to create unstable conditions at upper elevations throughout the day. Drifting and shooting cracks are evidence of unstable snow. Evaluate steep slopes carefully and use caution around wind-affected terrain. Identify terrain traps where even small avalanches could bury you.

    Weak, sugary facets formed in January are buried 2-3 feet in many locations. The likelihood of triggering a large avalanche is highest on very steep slopes above 8,000 feet that face west, through north, through east, where weak, faceted snow is best preserved. Warning signs will most likely not be present until it’s too late. Consider the consequences of an avalanche before committing to steep terrain. Watch out for terrain traps and identify slopes with a persistent slab problem (at or above 35° in slope angle, shady, and above 8000 feet).

    This is a great example of the persistent nature of the problem we are facing.

    This avalanche was triggered yesterday on a sheltered slope which had a skin and ski tracks on it.

    The Salt River and Wyoming Ranges have received less snow in the last 48 hours than zones to the north. However, westerly winds have been strong. Three inches in the last 48 hours and a couple more inches today will be enough to form very shallow slabs on steep, leeward slopes at upper elevations. Don’t let this catch you off guard above dangerous terrain. It doesn’t take much moving snow to knock you off your feet. Keep an eye out for drifts and shooting cracks, especially if snow continues to fall throughout the day.

    Watch for shallow wind slabs along ridges and below cliffs.

Avalanche Discussion

Expect a variety of snow surfaces getting into and out of the mountains.  A lack of snow at lower elevations continues to make access challenging. Recent warm temperatures formed crusts at middle and upper elevations that are now buried by recent storms. Any avalanches in recent snow could run farther and faster than you expect on these crusts. While upper elevations received 4-6” in the last 2 days, it’s possible that there are areas with more snow. Pay attention to new snow amounts and watch for heavily drifted areas along ridges and around rocky outcrops.
