Kernpunkte

This morning, most terrain has an overall LOW avalanche danger. Avalanche danger may rise to MODERATE if snow begins to quickly accumulate later today,expect sensitive drifts to form on mid and upper elevation slopes facing NW-N-E-SE.

Yesterday, observers were able to find shallow, hard slabs that cracked but were hesitant to slide. Although there is not much snow available to drift, the sustained strong westerly winds will work to scrape together what they can and may form small, stubborn slabs. This may change throughout the day. Once snow begins to fall, look for the strong winds to quickly build fresh, sensitive drifts.

On W-N-E aspects above 8000 feet, the Persistent weak layer is easy to identify, though it has become less reactive following the significant avalanche cycle on December 6th and 7th. We are currently observing a dichotomy in the terrain: slopes that slid earlier this month remain thin and continue to facet, essentially ‘lying in wait’ for a new slab to form. Meanwhile, slopes that remained intact struggle to maintain cohesion as daytime temperature swings chew at what slab remains.

This “dormancy” is temporary. The likelihood of triggering a slab avalanche that fails on the persistent weak layer will rise as the incoming storm builds a fresh slab over this weak foundation.

The last reported avalanches were on December 7th, with the last significant storm.

Snow and Weather

This morning, low-elevation temperatures are in the mid to upper 40s Fahrenheit. Winds began to increase yesterday afternoon and through the overnight hours, blowing out of the west, southwest 20-30 mph with gusts into the 40s or more. This is just the beginning. For today, daytime temperatures remain warm with lows in the mid-30s at 8000 feet. Winds wil remain elevated, blowing from the west 20-50 mph, with upper elevation exposed ridges seeing gusts in the 70s or higher throughout most of the day.

Snowfall begins late afternoon, with the bulk of the precipitation moving in after sunset. Expect the rain snow line to hover near ~8500’, potentially higher before dropping closer to 7000 feet as temperatures cool overnight. We could see 2 to 8 inches (.2 - 1.0 SWE) by tomorrow morning, with potential for more if we’re lucky.
