Date	Problem #1	Problem #2	The Bottom Line
Fri, April 7th, 2023	Deep Persistent Slabs		The avalanche danger is MODERATE above 1000′. The main concern is the lingering possibility of triggering a very large avalanche on a weak layer of snow buried 3-6′ deep. The likelihood of [Read More]
Thu, April 6th, 2023	Wet Loose	Deep Persistent Slabs	The avalanche danger remains MODERATE above 1000′. Loose wet avalanches could release naturally or be easily human triggered if the sun is able to break through the clouds today and melt the [Read More]
Wed, April 5th, 2023	Wet Loose	Deep Persistent Slabs	The avalanche danger is MODERATE for two very different issues. First is springtime wet loose avalanches late in the day. Daytime warming and sunshine could melt surface crusts enough on [Read More]
Tue, April 4th, 2023	Wind Slabs	Deep Persistent Slabs	The avalanche danger remains CONSIDERABLE above 2,500′. Strong easterly winds continue to impact the higher elevations. Watch for fresh wind slabs along ridgelines and in cross-loaded gullies. These are likely [Read More]
Mon, April 3rd, 2023	Wind Slabs	Deep Persistent Slabs	The avalanche danger is CONSIDERABLE above 2500′ as strong easterly winds will make it likely a person will be able to trigger a fresh wind slab avalanche up to a foot deep. [Read More]
Sun, April 2nd, 2023	Deep Persistent Slabs	Wind Slabs	The avalanche danger remains CONSIDERABLE above 1000′. We have seen multiple massive avalanches triggered by people over the past week, and dangerous conditions continue today. These avalanches are thousands of feet wide [Read More]
Sat, April 1st, 2023	Deep Persistent Slabs	Wind Slabs	The avalanche danger remains CONSIDERABLE above 1000′. Very large human triggered avalanches 3-6′ deep on a buried weak layer are still possible. Over the past 10 days there have been several close [Read More]
Fri, March 31st, 2023	Deep Persistent Slabs		The avalanche danger is CONSIDERABLE above 1000′. It is possible a person can trigger a very large avalanche 3-6′ deep or deeper on a weak layer of snow that was buried two [Read More]
Thu, March 30th, 2023	Deep Persistent Slabs	Wind Slabs	The avalanche danger remains CONSIDERABLE above 1000′ today. Human triggered avalanches 4-6′ deep are still possible and these very large avalanches can be triggered remotely from low angle terrain to the [Read More]
Wed, March 29th, 2023	Deep Persistent Slabs	Wind Slabs	The avalanche danger remains CONSIDERABLE above 1000′. It is still possible that a person can trigger a very large avalanche on a weak layer buried 4-6′ deep or deeper. Another one [Read More]
Tue, March 28th, 2023	Deep Persistent Slabs	Wet Loose	The avalanche danger is CONSIDERABLE above 1000′. Even though we are looking at another day of mild weather, a person can still trigger a very large avalanche on a weak layer buried [Read More]
Mon, March 27th, 2023	Deep Persistent Slabs	Wet Loose	The avalanche danger is CONSIDERABLE at all elevations. We have seen multiple very large human-triggered avalanches over the past two days, and similar activity is possible today. These avalanches have been triggered [Read More]
Sun, March 26th, 2023	Deep Persistent Slabs	Wet Loose	The avalanche danger remains CONSIDERABLE due to the possibility of triggering large and deadly avalanches. These are slabs 3-6+ feet deep and generally give no prior signs of instability. Several [Read More]
Sat, March 25th, 2023	Wind Slabs	Deep Persistent Slabs	The avalanche danger is CONSIDERABLE above 1000′ today. Wind slabs up to a foot deep are likely for human triggering and possible for natural avalanches today. The bigger issue is a weak [Read More]
Fri, March 24th, 2023	Wind Slabs	Deep Persistent Slabs	The avalanche danger is CONSIDERABLE above 1,000′. Dangerous avalanche conditions remain. Gusty northwest winds should be strong enough to create new wind slabs on top of the 3-6+ feet of [Read More]
Thu, March 23rd, 2023	Storm Slabs	Persistent Slabs	The avalanche danger remains HIGH above 1000′. Heavy snowfall and strong winds until yesterday evening will make human triggered avalanches very likely at upper elevations. The high level of uncertainty about the [Read More]
Wed, March 22nd, 2023	Storm Slabs	Deep Persistent Slabs	The avalanche danger is rising to HIGH today at all elevations. A storm bringing heavy snowfall and strong winds will rapidly increase the avalanche danger. Large natural and human triggered avalanches [Read More]
Tue, March 21st, 2023	Wind Slabs	Deep Persistent Slabs	The avalanche danger is CONSIDERABLE above 1000′. It is likely a person will be able to trigger a large avalanche where strong winds have created sensitive wind slabs up to 1-2′ deep. [Read More]
Mon, March 20th, 2023	Storm Slabs	Deep Persistent Slabs	The avalanche danger is CONSIDERABLE at all elevations today. Conditions remain dangerous after heavy snowfall brought 3-6′ new snow to our advisory area over the weekend. Despite the break in the weather [Read More]
Sun, March 19th, 2023	Storm Slabs	Persistent Slabs	The avalanche danger remains HIGH at elevations above 1,000′. Triggering a very large and dangerous avalanche is likely on all aspects. Between 3-5+ feet of snow has fallen in the [Read More]
Sat, March 18th, 2023	Storm Slabs	Persistent Slabs	The avalanche danger remains HIGH at all elevations. Two strong storms within 48 hours are rapidly loading the snowpack and creating very unstable avalanche conditions. Large to very large natural and [Read More]
Fri, March 17th, 2023	Storm Slabs		The avalanche danger will rise to HIGH today at all elevations. Up to a foot or more of snow and strong winds are expected, which will rapidly increase the avalanche danger. Natural [Read More]
Thu, March 16th, 2023	Storm Slabs		The avalanche danger is CONSIDERABLE above 2500′. Turnagain Pass received close to a foot of new snow in the past 24 hours combined with strong winds at upper elevations. Wind slab avalanches [Read More]
Wed, March 15th, 2023	Wind Slabs		The avalanche danger should rise to MODERATE today as several inches of new snow falls with moderate winds in the Turnagain Pass region. Wind slabs are expected to form in [Read More]
Tue, March 14th, 2023	Normal Caution		The avalanche danger will be LOW for most of the day, rising to MODERATE this evening as an approaching storm begins to impact our area. Conditions are expected to start out generally stable, but [Read More]
