Lo esencial

On mid and upper elevation steep slopes facing west through north and east, you will find CONSIDERABLE avalanche danger for triggering a Persistent Weak Layer avalanche. Avalanches in this terrain can be triggered remotely from a distance. Across all upper elevations, you will also find CONSIDERABLE danger for wind-drifted snow. Everywhere else will have MODERATE danger for new-snow avalanches.

Careful snowpack evaluation, cautious route-finding, and conservative decision-making will be essential today. Do not let your guard down with the sunny skies and fresh powder. It is still dangerous, and any avalanche you trigger could have severe consequences with how shallow the snowpack is.

    You need three ingredients to create an avalanche:

    • A weak layer (old Oct/Nov faceted snow) • A slab (recent storm snow) • A slope steep enough to slide, anything over 30 degrees. (You get to choose this)

    My advice: avoid slopes steeper than 30 degrees and stay off of — and out from under — any terrain facing the north half of the compass. Avalanches in this setup can be triggered remotely, meaning you can collapse the weak layer and start a slide from a distance.

    The westerly wind continues to blow at 10–20 mph, with gusts into the 20s along many upper-elevation ridgelines. These winds are actively drifting snow and creating fresh soft and hard slabs of wind-blown snow. Be on the lookout for slopes that are loading or have that rounded, pillow-like look. Cracking under your feet, a hollow feel, or stiff, chalky snow are all signs of fresh wind drifts you should avoid.

    On slopes where a weak layer of faceted snow sits underneath, even a small wind drift can overload the structure. The added weight from the wind can make an avalanche break deeper and wider, increasing the likelihood of a human or remote trigger and making the consequences much more severe.

    The new snow came in wet and heavy with rising temperatures. This has created an upside-down structure, where denser snow sits on top of lighter snow—an ideal setup for avalanches failing within the new storm snow. As you travel, pay close attention to how the new snow is bonding. Use small test slopes, shovel tilt tests, and slope cuts before committing to anything bigger. Cracking, collapsing, or any slab-like feel in the new snow are clear signs to dial it back.

Recent Activity

There were no new backcountry observations from the Ogden area. However, snow safety teams reported a natural avalanche cycle across the Ogden Skyline, as well as multiple explosive-triggered slides large enough to bury a person.

Snow and Weather

Under mostly clear skies, mountain temperatures remain cold, ranging from 16–27 °F. West wind continues at 10–20 mph, with gusts into the 20s across most upper-elevation wind sites.

Today we can expect mostly sunny skies. A small storm to our north could dip far enough south to bring a few clouds or even a couple of snowflakes, but overall it looks quiet. Winds are supposed to ease, but as of now they’re still plenty active across the upper terrain. Mountain temperatures will climb into the upper 20s to low 30s around 8,500 feet.

Storm totals are roughly 8 to 10 inches of new snow across the range containing 1.35 to 1.66 inches of water.
