Fri, January 5th, 2024	Storm Slabs	Glide Avalanches	The avalanche danger is CONSIDERABLE above 1000′. Human triggered avalanches releasing 2-3′ deep at the base of the storm snow from the past 48 hours remain possible due a weak layer at the old snow surface. Wind slabs forming along upper elevation ridgelines could cause natural or human triggered avalanches 1-2′ deep in exposed areas. In addition, [Read More]
Thu, January 4th, 2024	Storm Slabs	Glide Avalanches	As yesterday’s storm moves out the avalanche danger is dropping to CONSIDERABLE at the mid and upper elevations and MODERATE near sea level. This is the most dangerous time for human triggered avalanches. Although a few natural storm snow avalanches could occur today, more concerning is how easy it might be for people to trigger [Read More]
Wed, January 3rd, 2024	Storm Slabs	Glide Avalanches	The avalanche danger is rising to HIGH today due to a warm storm over the region. Heavy snowfall and strong east winds are expected to cause avalanches to release on their own. These storm snow avalanches could be large enough to send debris into the lower elevations where it’s raining. Travel in avalanche terrain in [Read More]
Tue, January 2nd, 2024	Wind Slabs	Glide Avalanches	The avalanche danger is CONSIDERABLE above 1,000’. Strong easterly winds will make natural and human triggered wind slab avalanches 1-2’ deep likely. The glide avalanche cycle continues to be a concern, these avalanches can be very large and release without warning. With low visibility expected today we recommend avoiding the areas where glide avalanches and [Read More]
Mon, January 1st, 2024	Wind Slabs	Glide Avalanches	Happy New Year! We’re kicking off 2024 with MODERATE avalanche danger above 1000′. Easterly winds are backing off slightly today, but will still be strong enough to move snow into sensitive wind slabs up to 6-12″ deep that may be easy to trigger. We are also concerned with the alarming rate of glide activity over the [Read More]
Sun, December 31st, 2023	Wind Slabs	Glide Avalanches	The avalanche danger is CONSIDERABLE above 2500′ and MODERATE below 2500′. Active weather returns to the area today, and natural and human-triggered avalanches will be likely above treeline as strong easterly winds build wind slabs up to a foot deep or deeper. We are only expecting a few inches of snow during the day, so slopes that are sheltered [Read More]
Sat, December 30th, 2023	Glide Avalanches	Wind Slabs	The avalanche danger is MODERATE above 1000′ today. Glide avalanches have been releasing at an alarming rate this week and we expect that to continue today.
