Lo esencial

The snow is stable and the danger LOW in most terrain. Avalanches are generally unlikely, but people still might trigger small avalanches of loose or wind drifted snow on very steep slopes.

    People could trigger small slab avalanches of wind drifted snow if they venture onto exposed upper elevation slopes. It is always wise to avoid travel on steep slopes with obvious deposits of wind drifted snow.

    • Suspect wind drifts or wind slabs are often smooth and rounded looking, like lenses or flying saucers.
    • Wind slabs often form on the lee side of exposed ridges and in and around terrain features. Watch for and avoid drifts on gully walls, under cliff bands, along sub-ridges, in scoops, saddles, and sinks.
    • Drifted snow is stiffer and more compacted than non-drifted snow, and hard drifts often produce hollow drum-like sounds when you walk on them.
    • Freshly formed wind slabs can be quite sensitive and are often remotely triggered. Older, harder wind slabs can be very stubborn and may not release until you get well out on them, suddenly failing like a big mouse trap.
    • Shooting cracks in drifted snow are a sure sign of instability.

Recent Activity

No new slab avalanches have been reported in the Logan Zone, but we've received reports of some activity in the Wasatch Range above Salt Lake City and Park City. See our updated list of Avalanches from across Utah HERE

Snow and Weather

Today will be mostly cloudy in the mountains, and it looks like cool and rather dry weather will persist through the weekend and next week. Today, high temperatures at 8500' will rise to around 27° F and a gentle south wind will blow 8 to 14 mph on the ridges. Observers report good powder riding conditions and much improved coverage after the mountains picked up more than two feet of new snow with this week's storm.

Shallow early season snow conditions exist, with only about a foot-and-a-half of total snow covering the rocks on most upper elevation slopes before this week's snow. Although the heavy fresh snow keeps you off the ground, there are numerous shallowly buried land mines out there. Keep your speed down and caution is required to avoid hitting shallowly buried rocks, stumps, or down trees.

Additional Info

  • Take the all-new online avalanche courses the UAC built for Know Before You Go or take other online courses listed on the KBYG website (Develop skills -> Online Learning).
  • Get your avalanche rescue gear ready for winter. Put fresh batteries in your transceiver and update the firmware. Inspect your shovel and probe. Get your airbag backpack ready by possibly doing a test deployment and update the firmware if it is an electric version.
