The avalanche danger is MODERATE above 1000′. Up to 3″ of snowfall and moderate winds today will create fresh wind slabs up to 2′ deep which are most likely to be found at upper elevations. Active weather will make natural avalanches possible in the afternoon and the avalanche danger will trend towards CONSIDERABLE in the alpine. [Read More]

Storm Slabs
The avalanche danger is MODERATE above 1000′. It is possible a person can trigger an avalanche 1-3′ deep, with the snow from last week sitting on top of weak surfaces. We’ve seen this combination of a slab on top of a weak layer throughout the advisory area, so approach steep slopes with caution today. Be on the [Read More]

The avalanche danger is MODERATE above 1000′ today. It is possible a person could trigger an avalanche 1-3′ deep or deeper below the new snow from the end of last week, which fell on firm crusts, buried surface hoar, and near-surface facets. Approach steep terrain carefully today, and keep in mind the very real possibility of triggering [Read More]

The avalanche danger is CONSIDERABLE above 2500′. New snow and strong winds over the past two days have built sensitive slabs 1-2′ deep or deeper on top of weak surfaces, with a layer of buried surface hoar present throughout most of the advisory area. These storm and wind slabs will remain reactive today despite calm weather. These [Read More]

Storm Slabs
The avalanche danger is CONSIDERABLE above 1000′. Strong winds over the past 24 hours and 2-6″ of snowfall expected today will make natural avalanches possible and human triggered avalanches likely. Wind slabs at upper elevations will be up to 2′ deep and could release on lower angle slopes and propagate more widely than normal due to a [Read More]

The avalanche danger is CONSIDERABLE above 2500′. Strong winds and new snow over the past 12 hours have created fresh wind slabs up to 2′ deep that are likely for human triggering and possible for natural avalanches. This storm buried a layer of surface hoar that existed on all aspects and elevations and could cause wind slabs [Read More]

The avalanche danger is LOW at all elevations this morning and expected to rise to MODERATE at the high elevations (above 2,500′) later this afternoon. Increasing easterly winds through the day should begin to form small wind slabs on steep wind loaded slopes. Later this evening into tonight, light snowfall with the strong winds will [Read More]

Normal Caution
Normal Caution
The avalanche danger is LOW at all elevations in the Turnagain Pass region. Triggering a large avalanche is unlikely. In exposed steep terrain with wind affected snow, watch out for small isolated wind slabs. Additionally, watch your sluff on steep sustained slopes and chutes. As always, give cornices a wide berth and limit exposure under glide [Read More]

The avalanche danger is MODERATE at elevations above 2,500′ on all aspects. Lingering wind slabs formed by the strong winds last Friday may still be triggered by people on steep slopes. These could be up to 2-3′ in depth and be quite hard, allowing a person onto the slab before it releases. Additionally, triggering a [Read More]

The avalanche danger is MODERATE above 1000′. Lingering wind slabs up to 3′ deep from the very strong east winds on Friday are still possible for a person to trigger today. The most likely place to find a wind slab is along upper elevation ridgelines, cross loaded gullies, and convex rolls. Warming temperatures this afternoon could also [Read More]

We have issued an Avalanche Warning through the National Weather Service that continues until 6 p.m. this evening. We are expecting heavy snowfall and strong winds today, which will lead to very dangerous avalanche conditions. Large natural avalanches failing 2-4′ deep or deeper in new and wind-drifted snow are likely, and some locations may see very large [Read More]

The avalanche danger is CONSIDERABLE above 1000′ today. A widespread natural avalanche cycle yesterday, which was responsible for multiple highway closures throughout Southcentral AK, is a wake up call that dangerous avalanche conditions exist. Conservative decision-making and cautious route finding are recommended today so we can give the snowpack time to adjust to the new load. Human [Read More]
