Date	Problem #1	Problem #2	The Bottom Line
Sat, April 15th, 2023	Wet Loose		The avalanche danger is MODERATE at all elevations today. Loose wet avalanches releasing naturally as the temperatures increase throughout the day are likely. These are typically small avalanches that occur on steep slopes with wet snow on the surface, but can become large enough to bury a person on larger slopes where the initial avalanche can pick [Read More]
Fri, April 14th, 2023	Wind Slabs		The avalanche danger is CONSIDERABLE above 2500′. Snowfall and wind throughout the day will build fresh wind slabs up to 1′ deep. The new snow is falling onto an icy snow surface and wind slabs forming along upper elevation ridgelines will be likely for human triggering and possible for natural avalanches. There is some uncertainty [Read More]
Thu, April 13th, 2023	Storm Slabs		The avalanche danger is MODERATE at all elevations today. Our main concern is the possibility of triggering an avalanche 1-3′ deep in the new snow that has fallen since Sunday. The odds of triggering an avalanche will increase if the sun stays out later in the day before clouds start to build. SEWARD/LOST LAKE: The latest round [Read More]
Wed, April 12th, 2023	Storm Slabs		A CONSIDERABLE avalanche danger exists above 2,500′ and MODERATE danger below 2,500′. Many different kinds of avalanches could be triggered today. These are wind slabs up to 2 feet deep above treeline, which should be the most likely due to yesterday’s winds. The others are storm slabs between 10-20″ deep in areas without wind loading, [Read More]
Tue, April 11th, 2023	Storm Slabs	Deep Persistent Slabs	The avalanche danger remains CONSIDERABLE at all elevations today. The most recent storm has dropped 1-3′ of low-density snow since Sunday, and it is likely a person will be able to trigger an avalanche within all of that new snow today. Be on the lookout for increasing chances of triggering an avalanche as the weather picks up [Read More]
Mon, April 10th, 2023	Storm Slabs	Deep Persistent Slabs	The avalanche danger is CONSIDERABLE at all elevations today. With heavy snowfall over the past 24 hours, it is likely a person will be able to trigger an avalanche 1-2′ deep today. The new snow has fallen on a variety of weak surfaces and is expected to be especially reactive. There is also a much smaller chance [Read More]
Sun, April 9th, 2023	Storm Slabs	Deep Persistent Slabs	The avalanche danger is expected to rise to CONSIDERABLE in the higher elevations this afternoon due to heavy snowfall and moderate winds. Both slab avalanches and loose snow sluffs composed of the new snow could release naturally and human triggered avalanches are likely in areas seeing more than 8″ of snowfall. In the lower elevations [Read More]
Sat, April 8th, 2023	Deep Persistent Slabs	Wind Slabs	The avalanche danger remains MODERATE above 1000′. Up to 6″ of new snow today with winds expected to pick up in the afternoon will form fresh wind slabs up to 1′ deep. Human triggered and natural avalanches are possible with these fresh wind slabs. Deeper down in the snowpack a buried weak layer of facets 3-6′ [Read More]
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 triggering an avalanche is decreasing, but the consequences still have us avoiding traveling on or below steep slopes. The danger is LOW below 1000′. [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 surface crust that exists on solar aspects. In addition we are still concerned about the potential for very large avalanches releasing on a buried weak [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 solar aspects that wet loose avalanches may be easy to trigger and could release on their own. The second problem is the unlikely chance a [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 to be up to a foot thick and easy to trigger. Additionally, there remains a chance a person could trigger a very large avalanche that [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. There is also still a small possibility of triggering a very large avalanche failing on weak snow buried 3-6′ deep or deeper. The danger is [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 and 3-6′ deep or deeper, and have been triggered remotely from low-angle terrain connected to steeper slopes. The only way to truly steer clear of [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 calls with avalanches on this layer and due to the consequences of triggering one of these avalanches we are keeping the avalanche danger elevated. In [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 weeks ago. We’ve seen multiple avalanches triggered remotely from low angle terrain on this layer over the past week, and conditions will be slow to [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 sides, below, or above steeper slopes. The potential for very large human triggered avalanches is driving us to keep the avalanche danger elevated even though [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 of these monsters occurred yesterday near Girdwood (no one caught). These slabs are deep, wide and running to valley bottoms in many cases. The only [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 4-6′ deep or deeper. We have seen multiple avalanches failing over 1000′ wide and running thousands of vertical feet since Friday, and similar activity is [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 remotely from low-angle terrain connected to steeper slopes, and avalanches have been running far into valley bottoms. Dangerous avalanche conditions exist right now, and the only [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 were triggered remotely yesterday by people from the bottom of slopes and adjacent to them (no one caught). Warmer weather today may make these easier [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 layer buried 3-6′ deep that has produced some very large natural avalanches in the past few days. It is possible for skiers or riders to [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 snow from the past 8 day storm cycle. New wind slabs should be in the 1-2′ deep range and could release naturally. They could also [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 current snowpack conditions and the potential for large to very large human triggered avalanches are the primary reason for keeping the danger elevated. Very large [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 will become very likely with today’s 12-18″ of snow forecast. In areas sheltered from the wind, avalanches will remain likely within the new storm snow. [Read More]
