Thu, February 3rd, 2022	Wind Slabs	The avalanche danger is CONSIDERABLE above 1000′ today. Strong winds and 2-6″ of new snowfall will be building fresh wind slabs up to 2′ deep that are likely to be triggered by a person and possible to cause natural avalanches. Cautious route finding and conservative decision-making is recommended in areas that are seeing active wind loading. Keep [Read More]
Wed, February 2nd, 2022	Wind Slabs	The avalanche danger is MODERATE above 1000′. Strong east winds yesterday built fresh wind slabs 1-3′ deep at upper treeline and alpine elevations which will be possible for a person to trigger today. Look for signs of recent loading on the snow surface, hollow feeling snow, and pillowy wind deposits on leeward aspects to identify terrain features [Read More]
Tue, February 1st, 2022	Wind Slabs	The avalanche danger is rising to CONSIDERABLE today on all aspects above 1,000′ due to a weather system bringing strong easterly winds. Wind slabs are expected to form through the day and could release naturally. Slabs could build to 1-3 feet thick and should be easy for people to trigger. Watch for blowing snow and [Read More]
Mon, January 31st, 2022	Wind Slabs	The avalanche danger is MODERATE above 1000′. It is possible to trigger an avalanche 2′ deep or deeper on lingering wind slabs that formed during last week’s storm. Approach steep slopes with caution, and avoid terrain that has been recently wind loaded. The most likely places to find unstable snow will be near ridgelines, on convex rolls, [Read More]
Sun, January 30th, 2022	Wind Slabs	The avalanche danger is CONSIDERABLE above 2500′, where it is likely a person could find a lingering wind slab and trigger an avalanche 2-3′ deep. As skies clear today, it will be important to remember we are less than 48 hours out from a big storm, which means we still need to approach steep slopes with [Read More]
Sat, January 29th, 2022	Wind Slabs	The avalanche danger is CONSIDERABLE above 1,000′ on all aspects. Yesterday’s heavier than predicted snowfall with last night’s strong winds will keep all storm snow avalanche problems in the forecast. Wind slabs will be the most likely to trigger and could be over 3′ in depth. It will also be possible to trigger storm slabs [Read More]
Fri, January 28th, 2022	Wind Slabs	The avalanche danger is CONSIDERABLE above 1000′ as winds continue to drift new snow into sensitive slabs 2′ deep or deeper. Human triggered avalanches will be likely with natural avalanches possible on wind-loaded slopes, becoming larger and more sensitive as snowfall continues and winds increase during the day. Cautious route finding and conservative decision making is [Read More]
Thu, January 27th, 2022	Storm Slabs	The avalanche danger is CONSIDERABLE above 1000′ today. Snowfall and moderate winds will build wind slabs up to 2′ deep that are likely to be triggered by a person and possible to produce natural avalanches. In protected areas the 8-16″ of new snow forecast from last night through tonight could produce storm snow avalanches at the interface [Read More]
Wed, January 26th, 2022	Wind Slabs	The avalanche danger is MODERATE on all aspects above 1,000′. Triggering a lingering wind slab or a new wind slab from today’s moderate east wind, is possible.
