Highlights

MODERATE: Heightened avalanche conditions exist on drifted upper elevation slopes steeper than 30 degrees. People could trigger dangerous slab avalanches of heavy, wind-drifted snow failing up to 2 feet deep on a sugary, persistent weak layer buried near the ground. Wet avalanches are possible in very steep terrain.

Evaluate snow and terrain carefully.
Slopes below about 7000 feet in elevation are bare of snow or have only minimal snow cover.

Wind slabs are likely to be stiff and stubborn due to the high snow density. Winds blowing from the west-southwest drifted any available snow into the lee side of ridges and terrain features, like subridges and gullies. Avoid steep recently or previously drifted slopes, especially those with a rounded, pillow-like appearance. Cracking under your feet, a hollow feel, or stiff, chalky snow are all signs of areas to avoid.

Even small avalanches can have serious consequences in shallow snow conditions, where a slide could drag you through rocks or downed trees below.

Stick to safe travel practices: travel with a partner, and cross or ride steep slopes one at a time while the rest of your group watches from a safe spot.

At upper elevations, weak, faceted snow from November is buried beneath a thick crust or multiple crusts and dense snow. On steep, wind-drifted slopes, people could trigger avalanches that propagate widely.

Collapsing, indicated by shooting cracks and/or whumpfs, is a warning sign of unstable snow.

Avalanches might be triggered remotely (from a distance or below).

Loose wet avalanches of rain-saturated snow are possible on steep slopes with sufficient snow cover. Roller balls, pinwheels, and wet sluffs indicate potential for wet avalanche activity.

Snow and Weather

Observers report damp and sticky riding conditions in the Central Bear River Range, and snow-covered access roads are melting out. It is already 42 °F at the 8400' Tony Grove Snotel this morning with 30" of total snow. Our Card Canyon site is showing 40 °F with 17" of total snow. On Logan Peak, winds are blowing from the southwest 30 to 40 mph and gusting to 47 mph this morning. On Paris Peak, winds are blowing from the south-southwest 15 to 25 mph.

Expect partly sunny conditions at 8500 feet today, with a high temperature near 45° F, and winds from the south-southwest around 14 mph. Tonight will be mostly cloudy, with a low temperature around 33°F, and increasing winds from the south-southwest 16 to 18 mph, with gusts as high as 34 mph. Warm temperatures up high will persist through Christmas Day, with blustery winds blowing from the south and southwest, and mountain rain.

***We're very happy to report that mountain temperatures will finally drop on Christmas Night, and snowfall is likely through Friday (snowfall could be heavy at times), with 8 to 16 inches of accumulation from the storm possible at upper elevations in the Bear River Range.
