The Avalanche Hazard is Moderate today in upper elevation wind affected terrain. Human triggered wind slabs are possible near ridge tops and will be most likely on Northerly slopes.  Pay attention in gullies and other terrain features that caught wind blown snow over the last few days as winds changed directions  The potential for wet, loose avalanches of various sizes will rise with the temperatures on sun affected terrain throughout the day.

The Avalanche Hazard is Moderate today. New snow with gusty varible winds have created wind slabs in upper elevations sitting on a variety of old snow surfaces including crusts, faceted snow and in some areas pockets of surface hoar.  Warm temperatures and the Sun will likely create loose-wet avalanches on slopes getting direct Sun. Utilize safe travel protocols especially in steep terrain, and evaluate slopes before committing.

The Avalanche Hazard is Moderate today.  New snow accumulations accompanied by gusty winds will create new avalanche problems.  Expect to see shallow, very sensitive wind and storm slabs sitting on a variety of old snow surfaces including crusts, faceted snow and in some areas pockets of surface hoar.  Enjoy the refresh on the snow this weekend but take time to refresh your avalanche mindset. New snow equals new avalanche problems.

The Avalanche Hazard is Low today.  Wet, loose avalanches may be possible on steep slopes that get direct sun, especially near exposed rock where the snowpack will be warming the fastest.  Isolated wind slabs are also something to think about if you are skiing or riding in steep northerly terrain, some of these wind slabs are resting on old crusts or faceted snow.  An experienced backcountry skier had a close call on 3/11/20 skiing a steep north facing gully.

The Avalanche Hazard is LOW today.   As the temperature increases, watch for increasing wet,loose avalanche hazard especially on slopes facing the sun.  You can reduce your exposure to wet, loose avalanches by staying on cooler, shady slopes where you are more likely to find soft snow.  Avoid traveling on or below large, overhanging cornices. Warm temperatures increase the potential for cornice failure.

The Avalanche Hazard is HIGH today.  Natural and Human triggered avalanches will be likely today throughout our forecast area. A combination of heavy snowfall,  winds gusting to 50+mph and warm temperatures have created dangerous avalanche conditions. Many natural and human caused storm slabs occurred over the last 3 days in the new snow layers.  Some of these avalanches were also releasing on weak layers created prior to the storm.  Today is NOT the day for skiing or riding steep terrain.

The Avalanche Hazard is Moderate today.  Natural and human triggered avalanches were reported earlier this week as the snowpack adjusted to wind and storm loading.  Avalanches are possible today on several weak layers in the upper 3 feet of the snowpack. Wind slabs have been widespread in high north facing terrain throughout the week.  Pay attention to the effects of warming temps through the day; roller ball and point release activity are signs of decreasing stability.

Human triggered avalanches are likely in wind affected areas. Triggering a shallow wind slab could result in a deeper avalanche that is able to step down into the layer of buried surface hoar or to the rotten facets near the ground.  Avoid wind affected terrain or slopes steep enough to slide.   Lower elevations still have a shallow, early season snowpack with a different set of hazards.

The Avalanche Hazard is Low Today. Use caution in or around wind-loaded, steep terrain. Shallow wind slabs with poor bonds exist in upper elevations. Wet-loose avalanche possibility will linger in the lower elevations today, and will be on the rise tomorrow as warm temperatures persist.

The Avalanche Hazard is Moderate Today. Gusty winds and around a foot of new snow have formed wind slabs in upper elevation leeward and exposed terrain, and may be sensitive to the weight of a skier or rider. Use caution in or around wind-loaded, steep terrain. Some of the new snow may not bond well to older Sun and rain crusts and may produce loose dry sluffs on slopes steeper than 30 degrees.

The Avalanche Hazard is Considerable Today. Gusty winds will continue to form wind slabs in upper elevation leeward and exposed terrain, and may be sensitive to the weight of a skier or rider. Natural avalanches are possible, especially in wind-loaded, steep terrain. Some of the new snow may not bond well to older Sun and rain crusts and may produce loose dry sluffs.

The Avalanche Hazard is Low today. Loose wet avalanches are possible as the snow pack receives sunlight, and daytime temperatures warm up. Avoid steep, rocky slopes that are getting the direct influence of the sun.  Later in the day, South winds around 30 MPH will be transporting snow and forming shallow wind slabs.

The Avalanche Hazard is Moderate today, The hazard will rise as the Sun and ambient temperature heats up the snow. The heat may produce cornice failures, rollerballs, and wet-loose slides on steep solar influenced slopes, especially near rocks.  Be cautious, and avoid sunny steep slopes that are receiving an excessive amount of heat where you are sinking above your boot tops.  Choose cooler aspects that are not receiving direct Sun.

The Avalanche Hazard is Moderate today.  Human triggered soft slab, avalanches up to 1 1/2 feet deep are possible on steep slopes that have been protected from the wind and Sun, where buried surface hoar is supporting a soft slab, and might be waiting for a trigger. Buried weak layers exist in the top 2 feet of the snow pack including surface hoar and graupel.  Cornices are overhanging and should be avoided right now.

The Avalanche Hazard is Considerable at all elevations. Up to 2 Feet of new snow by Friday along with gusty winds in the 20 MPH range are going to make Natural Avalanches possible and Human triggered avalanches likely. Use Good travel protocols like spreading out, and travel to avoid slopes steeper than 35 degrees. Lower elevation terrain, especially near rocks may produce small, loose-wet point releases, and or roller balls as the rain may creep up to 6,000 feet.

The Avalanche Hazard is Moderate on all upper elevation wind exposed, loaded, and cross loaded steep terrain where Human triggered avalanches are possible. The upper snow pack,  4-6 inches, or more is denser and overlying a layer of graupl that is not bonding well.  Good travel protocols like spreading out, and traveling one at a time on slopes steeper than 35 degrees. Solar aspects, especially near rocks may produce small, loose-wet point releases, and or roller balls.

The Avalanche Hazard is Considerable. Natural Avalanches are Possible and Human Triggered Avalanches are likely. Warmer and heavier snow is sitting on top of older loose snow. Strong South winds have created Wind slab hazard on wind loaded, and exposed slopes.  Storm slabs are likely in sheltered areas.  Travel cautiously in Avalanche terrain, and avoid wind loaded slopes.

The Avalanche Hazard is Moderate today. Natural Avalanches are unlikely and human caused Avalanches are possible.  Wind slab hazard exists on upper elevation, wind loaded, and exposed slopes.  Sluffing in the light density new snow is the biggest concern today and will be more likely in steep, rocky areas as the sun warms the surface of the snowpack.  Another series of storms will bring significant snowfall beginning tonight and will likely increase the hazard through the weekend.

The Avalanche Hazard is High today. Natural Avalanches are likely and Human caused avalanches are very likely.  Strong winds and heavy snow have created dangerous wind slabs on upper elevation, exposed slopes that will continue today with a little more wind and snow.  Storm slabs are also likely on slopes over 30 degrees. Wait for the storm to calm down and allow the snow pack to adjust and re-freeze. Cooling temperatures today could make slabs initially brittle and reactive?

The Avalanche Hazard is High today.  Natural avalanches are likely and Human triggered avalanches are Very Likely. Over 2 feet of snow is forecasted and ridge tops will see gusts upwards of 30 MPH over the next couple days that will continue to create wind slabs.  It is also possible to trigger soft storm slabs in the upper 2 feet. Cornices are growing, and will likely fail.  Travel in, or near avalanche terrain is not recommended today.
