Date	Problem #1	Problem #2	The Bottom Line
Mon, March 4th, 2024	Wind Slabs		The avalanche danger is expected to rise to MODERATE in the higher elevations (above 2,500′) as easterly winds increase today. Wind slabs, up to a foot deep, are expected to form along the ridgelines. Watching for winds strong enough to drift loose surface snow into shallow wind slabs will be the main concern. Slopes sheltered [Read More]
Sun, March 3rd, 2024	Normal Caution		The avalanche danger is LOW today at all elevations. With another day of quiet weather and a generally stable snowpack in our core advisory area, it is unlikely, but not impossible, that a person will trigger a slab avalanche. It is very likely that people will trigger dry loose avalanches, or sluffs. Avoid getting caught off guard [Read More]
Sat, March 2nd, 2024	Wind Slabs		The avalanche danger is MODERATE above 2500′. Lingering wind slabs up to 1′ deep from the past several days of NW winds remain possible for human triggering today. These are most likely to be found in steep terrain along ridgelines, gullies, and convex rollovers. Loose snow avalanches are also possible in sheltered areas with soft snow still [Read More]
Fri, March 1st, 2024	Wind Slabs		The avalanche danger is MODERATE above 1000′. The NW winds over the past 3 days have formed wind slabs 1-2′ deep in exposed areas which will be possible for a person to trigger today. Loose snow avalanches will also be likely for a person to initiate on steep terrain. Below 1000′ the avalanche danger is LOW. SUMMIT [Read More]
Thu, February 29th, 2024	Wind Slabs		A MODERATE avalanche danger exists above 1,000′. Triggering a wind slab avalanche, formed by yesterday’s northwest winds, is possible. Watching for, and avoiding, slopes where winds have deposited snow, or places that are still seeing drifting snow today, will be key. Additionally, loose snow avalanches (sluffs) could be easy to trigger on steep slopes and [Read More]
Wed, February 28th, 2024	Wind Slabs		The avalanche danger is CONSIDERABLE above 2,500′ due to strong northwest winds yesterday and forecast for today that will be creating fresh wind slabs. These can be 1 to 2′ deep and easy to trigger on slopes that are loaded by the wind. Although an avalanche is less likely, evaluate wind loaded slopes at mid [Read More]
Tue, February 27th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE above 2,500′ due to strong winds overnight creating wind slabs in the higher elevations. New wind slabs between 1 to 2 feet deep may be easily triggered on slopes with recent wind loading. The chance of finding a wind slab in the mid elevations is lower, but still exists in [Read More]
Mon, February 26th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger will be CONSIDERABLE today and could increase to HIGH overnight as a storm brings between 1 to 2 feet of new snow during the nighttime hours. In advance of the heavy snowfall today, strong winds and a few inches of snow should create new wind slabs in the higher elevations. These could [Read More]
Sun, February 25th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE above 2500′ and MODERATE above 1000′. Northwest outflow winds increased last night and are expected to continue this morning, making natural avalanches possible and human-triggered avalanches likely where the wind is loading snow into steep terrain. There is also a smaller chance that you may be able to trigger a bigger avalanche on a [Read More]
Sat, February 24th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE above 2500′. New snowfall combined with NW gap winds this afternoon are likely to cause natural and human triggered avalanches up to 1′ deep. Larger avalanches on a buried weak layer 1.5-3′ deep are possible on isolated slopes above 2000′. The avalanche danger is MODERATE below 2500′. Natural and human triggered avalanches are possible [Read More]
Fri, February 23rd, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is MODERATE above 1000′. The new snow that fell on Wednesday has been blown around by strong westerly winds making wind slabs 1-2′ deep possible for people to trigger today. Larger avalanches failing on a buried weak layer 1.5-3′ deep are possible on isolated slopes above 2000′. We are uncertain about how widespread these [Read More]
Thu, February 22nd, 2024	Wind Slabs	Persistent Slabs	Heavy snowfall last night and windy weather today will keep the avalanche danger CONSIDERABLE above 1,000′. Wind slab avalanches between 1-2′ thick may release naturally and should be easy for a person to trigger. These could be larger than expected if they break in a weaker layer in the snowpack. A conservative mindset is recommended. [Read More]
Wed, February 21st, 2024	Wind Slabs	Wet Slab	The avalanche danger is CONSIDERABLE at all elevations today. Large amounts of new and windblown snow in the upper elevations and rain falling on snow in the lower elevations will make natural avalanches possible and human triggered avalanches likely. Avalanches will be more likely in places that received greater amounts of snow like Girdwood, Portage, [Read More]
Tue, February 20th, 2024	Wet Slab	Storm Slabs	The avalanche danger is rising to HIGH today as a warm, wet, and windy storm impacts the region. Rain falling on snow in the mid elevations and strong wind and new snow in the high elevations will create dangerous avalanche conditions. Natural avalanches are most likely in Girdwood, Portage, and Placer Valleys and possible in [Read More]
Mon, February 19th, 2024	Wind Slabs	Persistent Slabs	The danger remains CONSIDERABLE above 2500′. A storm is expected to arrive this afternoon, with increasing east winds making wind slab avalanches likely through the day. This storm will start adding stress to a deeper weak layer of snow that may produce bigger avalanches. Pay attention to changing conditions, and be prepared to adjust your travel plans [Read More]
Sun, February 18th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE above 2500′. The easterly winds are expected to back off slightly, but will still be moving snow into sensitive slabs in the upper elevations, making it easy to trigger an avalanche. There is also a weak layer of snow buried deeper in the snowpack that has the potential to make bigger avalanches, [Read More]
Sat, February 17th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE above 1000′. Strong winds continue to form wind slabs at treeline and above which remain likely for human triggering today. A weak layer buried 1-3′ deep could also cause very large human triggered avalanches. We recommend sticking to low angle terrain to avoid this widespread weak layer. Below 1000′ the avalanche danger [Read More]
Fri, February 16th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE above 1000′. Human triggered and natural avalanches in areas being actively wind loaded are likely. A weak layer buried 1-3′ deep could also produce very large avalanches. We recommend sticking to low angle terrain and being aware of overhead runout zones to avoid avalanches today. Below 1000′ the avalanche danger is MODERATE. A thick [Read More]
Thu, February 15th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE as this week’s wind storm continues to make larger natural and human-triggered avalanches likely where sensitive wind slabs are forming. We are also concerned with a weak layer of snow buried 2 to 3′ deep that will make even bigger avalanches failing deeper in the snowpack possible, even in sheltered terrain. [Read More]
Wed, February 14th, 2024	Wind Slabs	Persistent Slabs	Avalanche danger is CONSIDERABLE at all elevations for a variety of dangerous avalanche issues. In the mid and high elevations, wind slab avalanches may still release naturally due to strong east winds. Wind slabs could be up to 3 feet deep and easy for a person to trigger. A person could also trigger a slab [Read More]
Tue, February 13th, 2024	Wind Slabs	Persistent Slabs	Very strong east winds are impacting the mountains and raising the avalanche danger to HIGH at the mid and upper elevations. Naturally occurring wind slab avalanches are likely and human triggered avalanches are very likely on any wind loaded slope. Travel in avalanche terrain is not recommended during this stormy and windy weather, including runout [Read More]
Mon, February 12th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE above 1000′. Very strong easterly winds will increase the chances of triggering a large avalanche where snow is being blown into sensitive slabs, and we will most likely see some natural avalanches as the winds pick up. This will be adding stress to a deeper layer of weak snow that has [Read More]
Sun, February 11th, 2024	Persistent Slabs	Wind Slabs	The avalanche danger is CONSIDERABLE above 1000′. It is likely a person will be able to trigger a large avalanche on weak snow buried 2 to 3′ deep. It will also be easy to trigger avalanches near the surface where recent strong winds have blown the snow into sensitive slabs that will remain reactive today. Don’t let [Read More]
Sat, February 10th, 2024	Persistent Slabs	Storm Slabs	The avalanche danger remains HIGH above 1000′. The potential for very large human triggered avalanches still exists due to the heavy snowfall yesterday on top of buried weak layers 2-3′ deep. We recommend a very conservative approach to avalanche terrain today. Southerly winds could cause natural avalanches in wind exposed areas which could run out to lower [Read More]
Fri, February 9th, 2024	Persistent Slabs	Storm Slabs	The avalanche danger is HIGH at all elevations. A strong storm started yesterday evening with winds gusting to 90 mph and up to a foot of new snow already fallen. Today the heavy snowfall will continue and we recommend avoiding avalanche terrain and runout zones of avalanche paths, which could produce avalanches running into valley bottoms. [Read More]
