Out of date — this forecast expired 2 years ago. You’re viewing past conditions, not the current bulletin.

Highlights

Heightened avalanche conditions exist at upper elevations in the backcountry, the danger is MODERATE, and people could trigger small soft slab avalanches of new snow and/or stiffer wind slab avalanches on slopes steeper than 30° facing west, north, and east. Although there's probably not enough snow to bury you, a ride over rocks in even a small avalanche could be quite dangerous.

    Shallow avalanches of stiff, drifted snow (wind slab avalanches) are possible for people to trigger in upper-elevation terrain on slopes steeper than 30°.

    • What were obvious drifts yesterday are likely buried and hidden today by last night's fresh powder.
    • Hard wind slabs often let people get out on them before releasing like a giant mouse trap.
  • Storm Slabs

    Storm slab and loose avalanches of new snow are possible in the coming days as fresh snow accumulates and drifts on slopes with shallow, very weak snow.

Recent Activity

No avalanches have been reported recently in the Logan Zone, but remember, avalanches are most likely during and just after storms on slopes steeper than 30°.

Snow and Weather

Heavy snowfall and drifting by strong winds elevated avalanche conditions in the backcountry. Weak, sugary, or faceted snow from earlier in November is widespread in upper-elevation terrain. Today, in places where this weak snow exists on slopes steeper than 30°, a person could trigger loose or soft slab avalanches of storm snow and/or small hard slab avalanches of wind-drifted snow.

  • The 8500' Tony Grove Snotel reports 5 inches of new snow in the last 24 hours, with 18 inches of total snow on the ground. I'm also reading 5 inches of new snow at the 8800' UAC Card Canyon weather station, with 22" of total snow.
  • The winds came around from the northwest and diminished significantly overnight. Currently, the wind is blowing from the northwest 18 mph, with overnight gusts around 30 mph at 9700' at the CSI Logan Peak weather station and 15 mph with gusts of around 25 mph on Paris Peak.
  • After a break Sunday afternoon through Monday, storminess will return with the potential for decent additional accumulations in the mountains and winter driving conditions leading up to the Thanksgiving Holiday.

Shallow, early-season conditions exist in the Bear River Range. Keep your speed down, hitting shallowly buried rocks, stumps, or down trees could end your season before it really begins......
