Date	Problem #1	Problem #2	The Bottom Line
Thu, February 8th, 2024	Wind Slabs	Persistent Slabs	A storm is moving in today and peaking tomorrow, which will create dangerous avalanche conditions. Today the danger is CONSIDERABLE above 1,000′ where increasing winds are expected to blow snow into fresh wind slabs 1-2′ deep. Natural wind slab avalanches could occur and should be easy to trigger by a person. Additionally, a person could trigger [Read More]
Wed, February 7th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE above 2,500′ today. A storm bringing mostly wind has arrived creating fresh wind slabs up to one foot deep. This new load will add stress to a weak layer of snow buried in the snowpack that could produce a larger avalanche two feet deep or more. This deeper weak layer [Read More]
Tue, February 6th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is MODERATE at all elevations. Triggering a slab avalanche around a foot deep is possible. The chances are more likely on wind loaded slopes but this could also happen on slopes that appear to not have been wind loaded. Over the weekend three of these types of avalanches were triggered with three [Read More]
Mon, February 5th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is CONSIDERABLE above 1000′ today. Strong easterly winds will build another round of sensitive wind slabs, making it easy to trigger an avalanche up to a foot deep within the new snow from the past few days. This will also be adding stress to the weak layer of snow that was buried a week [Read More]
Sun, February 4th, 2024	Wind Slabs	Glide Avalanches	The avalanche danger is CONSIDERABLE above 2500′. New snow and strong winds overnight will make it easier to trigger an avalanche where another round of wind slabs have formed. There is also still a chance that you could trigger a deeper avalanche on the older wind slabs that formed near the end of last week, which buried [Read More]
Sat, February 3rd, 2024	Wind Slabs	Glide Avalanches	The avalanche danger is MODERATE above 1000′. Wind slab avalanches 1-2′ deep are possible for a person to trigger today. An incoming storm this afternoon will bring increasing easterly winds that could form fresh wind slabs and cause natural avalanches on steep wind loaded features at upper elevations. Glide avalanches continue to be a concern and we [Read More]
Fri, February 2nd, 2024	Wind Slabs	Glide Avalanches	The avalanche danger is MODERATE at all elevations today. Human triggered and natural avalanches 1-2′ deep caused by wind transported snow are the most likely type of avalanche to encounter. Glide avalanches are also a concern on slopes with existing glide cracks. We recommend avoiding spending time underneath glide cracks because these avalanches release randomly and are [Read More]
Thu, February 1st, 2024	Wind Slabs	Glide Avalanches	Avalanche danger is expected to rise to CONSIDERABLE in the upper elevations (above 2,500′) as strong NW outflow winds develop today. Wind slabs can form quickly on any slope seeing active wind loading. These slabs could be 1-2 feet deep and may release naturally or be easily triggered by a person. In areas out of [Read More]
Wed, January 31st, 2024	Wind Slabs	Glide Avalanches	The avalanche danger is MODERATE at all elevations. East winds created fresh wind slabs 1-2′ deep yesterday and new wind slabs will also be forming today as winds pickup throughout the day. It is also possible to trigger an avalanche in the new snow in sheltered areas, especially where more new snow fell over the [Read More]
Tue, January 30th, 2024	Wind Slabs	Glide Avalanches	The avalanche danger remains CONSIDERABLE at the higher elevations (above 2,500′) where strong easterly winds created wind slabs in the 8-18″ of new light snow from yesterday. Wind slab avalanches should be easy to trigger on slopes with wind deposited snow. The danger is MODERATE below 2,500′ for the chance of finding a new wind [Read More]
Mon, January 29th, 2024	Storm Slabs	Glide Avalanches	Snow has returned to the area, and the avalanche danger has increased to CONSIDERABLE. We should see up to a foot of new snow on the ground before the storm breaks up this afternoon, which has fallen on weak older snow. It will be easy to trigger an avalanche today, and increasing winds through the [Read More]
Sun, January 28th, 2024	Glide Avalanches		The danger remains MODERATE above 1000′. A storm is heading our way starting this afternoon, but with most of the snow expected to arrive after sunset, we do not expect avalanche danger to rise until tonight. Our main concern for now remains the active glide cycle that we have been seeing for over a month now. These [Read More]
Sat, January 27th, 2024	Glide Avalanches		The avalanche danger remains MODERATE above 1000′ due to the threat of glide avalanches releasing up to 7′ deep and causing very large avalanches. These avalanches occur at random times on slopes with existing glide cracks, so being aware of any glide cracks on the slopes above you is critical to avoid this hazard. Gap winds gusting [Read More]
Fri, January 26th, 2024	Glide Avalanches		The avalanche danger is MODERATE today above 1000′. Glide avalanches releasing down to the ground (4-6′ deep) are our primary concern. Keep an eye out for glide cracks on the slopes above you and try to minimize the amount of time you spend underneath. In addition, wind speeds are expected to increase slightly today and small wind [Read More]
Thu, January 25th, 2024	Glide Avalanches		The avalanche danger remains MODERATE above 1000′. Glide avalanches releasing down to the ground are the main concern; two of these released last night. These can avalanche at random and we don’t want to be in the wrong place at the wrong time. Keep an eye out for glide cracks and try to avoid spending time underneath [Read More]
Wed, January 24th, 2024	Glide Avalanches		Avalanche danger remains MODERATE above 1000′. The main concern are glide avalanches spontaneously releasing in popular areas. Glide avalanches are large and destructive. Keep a close eye out for glide cracks and limit spending any time under them. Otherwise, triggering an avalanche is unlikely and normal mountain hazards exist, such as cornice falls, sluffs on steep slopes, [Read More]
Tue, January 23rd, 2024	Glide Avalanches		The avalanche danger remains MODERATE above 1000′. Glide avalanches releasing down to the ground are the main concern. They release at random and are not triggered by people. Keep an eye out for glide cracks above you and try to avoid spending time underneath. Otherwise, normal mountain hazards like cornices, dry loose avalanches, and small wind [Read More]
Mon, January 22nd, 2024	Glide Avalanches		The avalanche danger remains MODERATE above 1000′. Our main concern is the continued glide avalanche activity we have been seeing throughout the advisory area. These avalanches are large, destructive, and impossible to predict so be sure to avoid traveling under open glide cracks as much as possible. The danger is LOW below 1000′. SNUG HARBOR/LOST LAKE/SEWARD: These southern [Read More]
Sun, January 21st, 2024	Glide Avalanches		Avalanche danger remains MODERATE above 1000′, and our main concern is the active glide avalanche cycle we’ve been seeing for the past few weeks. Glide avalanches are large destructive, and unpredictable. Be aware of active glide cracks above popular routes, and limit spending any time under them. The danger is LOW below 1000′. [Read More]
Sat, January 20th, 2024	Glide Avalanches		The avalanche danger is MODERATE above 1000′ today. Glide avalanches releasing down to the ground are the main concern. These avalanches release randomly and are very destructive. Keep an eye out for existing glide cracks on slopes above you and try to avoid spending time underneath. Otherwise, normal mountain hazards like cornices, dry loose avalanches, and small [Read More]
Fri, January 19th, 2024	Glide Avalanches	Wind Slabs	The avalanche danger is MODERATE above 1000′ today. Glide cracks continue to release across the forecast area, causing very large and destructive avalanches. Be aware of any glide cracks on the slope above you to identify areas where there is a risk of being caught in the runout of a glide avalanche. Lingering wind slabs about 1′ [Read More]
Thu, January 18th, 2024	Glide Avalanches	Wind Slabs	The avalanche danger is MODERATE above 1,000′ for the threat of glide avalanches and wind slab avalanches. These are two very different concerns but both are easy to look for. Limit any time under those dark brown glide cracks in case they spontaneously avalanche. Additionally, watch for slopes and cross-loaded gullies with wind deposited snow. [Read More]
Wed, January 17th, 2024	Wind Slabs	Glide Avalanches	The avalanche danger is CONSIDERABLE above 2,500’ as an outflow wind event blows through the region. It will be likely for a person to trigger an avalanche 1-2’ deep in freshly windblown snow. Natural wind slab avalanches will also be possible in the higher terrain. Additionally, glide avalanches remain a concern above 1,000’ where the [Read More]
Tue, January 16th, 2024	Glide Avalanches	Wind Slabs	The avalanche danger will start out MODERATE and rise to CONSIDERABLE above 2500′ this afternoon, as strong NW outflow winds are expected to pick up around 3pm. The chances of both natural and human triggered wind slab avalanches 1-2′ deep will increase quickly once the winds pick up and start transporting snow. Glide avalanches are also a concern [Read More]
Mon, January 15th, 2024	Glide Avalanches	Wind Slabs	Avalanche danger remains MODERATE above 1000′ today. As the active glide avalanche cycle continues, our main concern is the alarming rate of glide avalanches in busy areas. You can manage this problem by spending as little time as possible under glide cracks. Consider using alternate routes whenever possible if your normal route travels under an open glide [Read More]
