Kernpunkte

The avalanche danger is MODERATE for the isolated chance of triggering a slab avalanche 2 to 4 feet deep, on upper elevation slopes facing northwest through easterly, especially those with any recent drifts of wind blown snow.

There is also a MODERATE danger for triggering a new wind slab or wind drift, which will be scattered throughout the mid and upper elevation terrain.

    No recent avalanches have been reported, but poor snow pack structure remains on shady mid and upper elevation slopes. This layering is known as “strong over weak” - a denser slab of snow above a persistent weak layer of sugary, faceted snow. While this layering has not produced avalanches the past few days, it’s hard to completely trust it.

    The strong winds will find some snow to drift, adding a little more weight in the form of wind drifts. Steep, rocky north and north easterly facing terrain with fresh wind drifts is particularly suspect, and even slopes that have already slid this season can slide again.

    Wind directions have ranged from the southwest to northwest, and speeds are strong enough to erode and drift some snow. Clues are an etched, hard snow surface where the winds have eroded snow and hard, rounded, hollow sounding drifts where snow has been deposited. With fast wind speeds, look for the new wind slabs, or drifts, at both upper and mid elevations. They will be on the lee sides of ridge crests and around terrain features, like gully walls, sub ridges and down into open bowls.

Recent Activity

No new avalanches reported.

Snow and Weather

An arriving “storm” may produce a few inches of snow today, but the bigger impact will be the westerly winds. They ramped up a few hours ago, with ridgelines averaging 25 to 35 mph, gusting in the 60s, and mid elevations averaging 15 to 25 mph, with gusts to 40. Speeds will gradually decrease throughout the day. Temperatures are in the 20s at the mid elevations, with a few 30s at the trailheads, and won’t warm too much today.

Wondering where all the powder went? Sunny slopes are crusted, and multiple wind events in the past 7 days have created widespread wind damage. Search for patches of settled powder on shady, sheltered slopes.

Brighton’s Great Western weather station, 10,565’ shows the recent wind events. Again, speeds will decrease throughout the day.
