Highlights

It will be possible to trigger slabs in very steep terrain in the upper elevations today. A lack of significant loading over the last four days has allowed the snowpack to gain strength. Below 9,000 feet avalanches are unlikely except in steep isolated pockets. While overall snow depths have increased over the last week, coverage remains shallow. Due to the thin coverage, involvement in an avalanche carries the potential for significant injury. Evaluate terrain and the snowpack carefully and consider the consequences prior to committing to a slope.

    Slabs formed by strong winds during recent snowfall lie upon crusts and faceted snow that was buried on December 5th. This weak layer is widespread at the upper elevations and reaches down to an elevation of 8500 feet on west through north to east aspects. Although these slabs have become less reactive, they could still be human triggered in very steep terrain with average slab depths of one to two feet.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )The dry and quiet weather will continue overnight and into tomorrow. Skies will start out mostly cloudy and slowly clear throughout the day as we will be under a weak ridge of high pressure. Temperatures during the day will climb into the high twenties at mid elevations. Ridgetop winds will be out of the west at 15-20 mph. No precipitation is forecasted.Another day without adding stress to the snowpack will help to further stabilize any weak interfaces within the snowpack. While many slopes in the mid and upper elevations harbor persistent weak layers, field observations continue to show a general lack of avalanche activity on those layers. Very steep slopes will be the most likely terrain to trigger slab avalanches up to two and a half feet in depth. Expect the avalanche danger to remain Moderate above 9,000’ and Low in the mid and lower elevations.
