Date	Problem #1	Problem #2	The Bottom Line
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. There is a smaller chance that a person may trigger a very large avalanche at the interface between last week’s storm snow and the weak [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 today, it remains likely that a person could trigger a very large avalanche with all of this new snow. It will be important to approach [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 past 4 days on older weak snow and crusts. The storm is moving out today but ridgetop winds are continuing to blow. Natural avalanches are [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 human triggered avalanches 2-4’+ deep are almost certain. We recommend avoiding avalanche terrain today and being aware of any overhead slopes that could release naturally [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 and human triggered avalanches 1-3′ deep in areas with active wind loading are very likely. In areas sheltered from the wind natural and human triggered [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 1-2′ deep are likely to be triggered by a person and possible to release naturally. In areas sheltered from the wind new snow avalanches are [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 the higher elevations or in exposed areas in the trees. They should be generally small, up to a foot at the most, but possible for [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 the avalanche danger will be on the rise later in the day as the weather picks up. As always, maintain safe travel protocol while you [Read More]
Mon, March 13th, 2023	Normal Caution		The avalanche danger is LOW at all elevations. It is unlikely a person will trigger an avalanche today, but not impossible. Be sure to stick with safe travel protocols, including only exposing one person at a time to steep terrain, watching your partners from safe spots, and always traveling with a beacon, shovel, and probe. PETE’S / [Read More]
Sun, March 12th, 2023	Normal Caution		The avalanche danger remains LOW at all elevations. Although triggering an avalanche will be unlikely, we still need to look for signs of unstable snow. If the sun heats up steep south facing slopes enough, small wet loose avalanches could be triggered. Additionally, watch for old wind slabs in upper elevation steep rocky terrain. Give [Read More]
Sat, March 11th, 2023	Normal Caution		The avalanche danger is LOW at all elevations. Generally safe avalanche conditions exist in the majority of the forecast area. Human triggered avalanches in isolated locations are unlikely but not impossible, so it is important to continue evaluating conditions in your area. Using safe travel protocols will stack the deck in your favor just in case you [Read More]
Fri, March 10th, 2023	Normal Caution		The avalanche danger is LOW today. Human triggered avalanches are unlikely, not impossible. Gusty outflow winds will make reactive wind slabs in isolated steep terrain, but these should stay small due to the lack of soft snow on the ground for building slabs. Be aware of the potential for finding one of these unstable pockets of snow, [Read More]
Thu, March 9th, 2023	Wind Slabs		The avalanche danger is MODERATE above 2500′. NW winds are picking up this morning which could make natural or human triggered avalanches up to 1′ deep possible at upper elevations. We expect these to be isolated to higher elevation ridgelines and areas that are exposed to gap winds like along Turnagain Arm. On the southern end of [Read More]
Wed, March 8th, 2023	Wet Loose		The avalanche danger remains MODERATE above 1,000′. Another unseasonably warm day with abundant sunshine will again melt the surface snow on southerly aspects creating wet loose avalanches on steep slopes facing the sun. These can occur on their own as well as be easy to trigger. There is a possibility that these smaller avalanches could [Read More]
Tue, March 7th, 2023	Wet Loose		The avalanche danger is MODERATE above 1000′. Unusually warm temperatures and sunny skies will make natural and human triggered wet loose avalanches likely, especially on southern slopes. These loose snow avalanche can build up steam on larger slopes and reach sizes large enough to bury a person. It is also possible that a loose snow avalanche could [Read More]
Mon, March 6th, 2023	Wet Loose		The avalanche danger is MODERATE above 1000′ today. Warm temperatures and mostly sunny skies will make loose avalanches the main concern, and there is a smaller possibility that these loose snow avalanches could pull out bigger slabs on isolated slopes. It is difficult to predict how the snowpack will respond to the first major warming event of [Read More]
Sun, March 5th, 2023	Wind Slabs	Wet Loose	The avalanche danger is MODERATE on slopes above 1,000′. Triggering a lingering wind slab formed during the strong NW winds is possible. These are in the 1-2′ deep range and may be found off ridgelines, in cross-loaded gullies, and on rollovers. Additionally, solar warming this afternoon could affect the southerly aspects enough to make some [Read More]
Sat, March 4th, 2023	Wind Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE above 2500′. Continued NW outflow winds are making natural wind slabs up to 1′ deep possible and human triggered avalanches likely in areas with active wind loading. These winds tend to favor areas along Turnagain Arm and other places where gaps winds are common. In areas sheltered from the recent winds the [Read More]
Fri, March 3rd, 2023	Wind Slabs	Persistent Slabs	The avalanche danger will remain CONSIDERABLE above 1000′ as northwest winds ramp up again today. It is likely a person will be able to trigger an avalanche a foot deep or deeper where winds are forming sensitive slabs through the day. It will be less likely to encounter unstable snow in areas where winds stay calm during [Read More]
Thu, March 2nd, 2023	Wind Slabs	Persistent Slabs	The avalanche danger will remain CONSIDERABLE above 1000′ as northwest outflow winds continue today. It is likely a person will be able to trigger a wind slab avalanche 1-2′ deep where winds are forming sensitive slabs– especially near ridgelines, convexities, and steep gullies. Safe travel will require identifying and avoiding steep wind-loaded features. The danger is MODERATE below 1000′, [Read More]
Wed, March 1st, 2023	Storm Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE above 1,000′. Human triggered avalanches are likely on slopes with more than 6″ of new snow that have seen, or are seeing, active wind loading. Wind slabs are expected to be 1-2′ deep and easy to trigger. On slopes out of the wind, the danger is MODERATE. Here we may [Read More]
Tue, February 28th, 2023	Storm Slabs	Persistent Slabs	A storm moving in will increase the avalanche danger to CONSIDERABLE above 2,500′ through the day and may reach HIGH overnight tonight. The danger is expected to remain MODERATE below 2,500′ today, where less snow and wind is expected, but will also increase in the overnight hours. Wind slabs are likely to develop by this [Read More]
Mon, February 27th, 2023	Wind Slabs	Persistent Slabs	The avalanche danger is MODERATE above 1000′. The strong northwest outflow winds from the past two days have built sensitive wind slabs 1-2′ deep that will remain possible for a person to trigger today. We’ve seen loading on all aspects with this round of wind, so be sure to carefully assess steep slopes and avoid traveling in [Read More]
Sun, February 26th, 2023	Wind Slabs	Persistent Slabs	The avalanche danger remains CONSIDERABLE in the upper elevations where winds continue to blow snow into drifts and slabs. Human triggered wind slab avalanches are likely on slopes that have, or are being, wind loaded. The danger is MODERATE on slopes out of the wind. Here there is still a chance of triggering a slab [Read More]
Sat, February 25th, 2023	Wind Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE above 2500′. Northwest outflow winds up to 30 mph are expected today which will make human triggered avalanches up to 1′ deep likely and natural avalanches possible. It is also possible to trigger an avalanche on a buried weak layer 1-3′ deep. Careful snowpack evaluation is recommended, especially in areas with active [Read More]
