In sintesi

Avalanches are unlikely in most areas, and the danger is LOW. Exceptions and areas of MODERATE danger may exist in some terrain at upper elevations.

Dangerous avalanches failing on a persistent weak layer from November are unlikely but possible on slopes steeper than 30 degrees in isolated rocky terrain with thin snow cover.

Use usual caution.

    Up high and on slopes facing west, north, and east, avalanches failing on a persistent weak layer are possible in isolated outlying terrain where previously wind-drifted snow overlies weak, sugary snow from November. Dangerous hard slab avalanches are increasingly unlikely as the shallow, sugary snow from November is buried and pressed into terrain anchors by a deep layer of heavy, hardening snow.

    • Unlikely avalanches failing on a persistent weak layer might still be triggered remotely, from a distance, or below.
    • Cracking and collapsing (or whumpfs) are definite signs of instability, but they may not be present when avalanches occur.
    • Avoid stiffer, drifted snow on the lee side of prominent ridges and in and around terrain features like gullies, sub-ridges, scoops, mid-slope rollovers, and rock outcroppings or cliff bands.

Additional Info

We went up to the Ballroom in Beaver Envy (Amazon Face) on Saturday and this is what we found,

This fall, we installed two new weather stations in the Logan Zone. The Paris Peak Weather Station (available HERE) and the Card Canyon Weather Station (available HERE)

Special Announcement

Join the UAC and Young Powersports in Centerville on Thursday, December 14, from 5 - 7 PM for a FREE avalanche transceiver training. Details here.

Snow and Weather

The Tony Grove Snotel at 8400' reports 54 inches of total snow, and it's 25 F. The wind sensor on Paris Peak is rimed or iced up and not reporting. Observers also report encountering a thin rime crust near the surface of the powder in upper-elevation meadows in the Central Bear River Range.

Expect mostly cloudy weather in the mountains today, with a chance of snow flurries. 8500' high temperatures will be around 27 F, and winds will blow 9 to 11 mph from the east.

Seasonally cold temperatures, stronger east winds, and sunny conditions are expected Wednesday. High pressure is expected to dominate the weather pattern for a while, and no storms are in the current forecast. However, confidence is low, but some hope exists for early next week with a series of weak systems that may bring some snow.

General Announcements

  • Taking time to check your companion rescue gear and practice with your transceiver is essential. watch a short video here
  • IMPORTANT: Read Mark's blog about electromagnetic interference of avalanche transceivers HERE
  • Our 20th annual Pray For Snow fundraiser party was a huge success. Thanks for coming and showing your support!
  • We will update this forecast on Wednesday morning.
