LOW avalanche danger exists for all elevations today. "LOW danger" does not mean "no danger". Continue to use normal caution while traveling in the backcountry to minimize the chances of an unpleasant surprise.

MODERATE avalanche danger exists at all elevations due to new and old wind slabs and a possible lingering deep slab problem. Human triggered avalanches remain possible today. 

CONSIDERABLE avalanche danger will exist through the morning and into the afternoon due to wind slab, storm slab, and deep slab avalanche problems.  As the storm intensifies this afternoon, avalanche danger will rise to HIGH and continue overnight.  Dangerous avalanche conditions will exist with large and destructive avalanches possible.  Travel in avalanche terrain is not recommended.

CONSIDERABLE avalanche danger exists at all elevations due to a wind slab avalanche problem and uncertainty associated with continued storm slab and deep slab avalanche problems. Large destructive avalanches remain possible today.

CONSIDERABLE avalanche danger will exist at all elevations today. This afternoon it will increase to HIGH avalanche danger as the next strong winter storm arrives over the region. Expect large widespread avalanche activity during this storm. Dangerous and complex avalanche conditions exist with a mix of wind slabs, storm slabs, and deep persistent slabs.

MODERATE avalanche danger continues with a persistent slab avalanche problem at all elevations.  Large and destructive avalanches are still a concern throughout the forecast region.  Avalanche danger is expected to further rise over the next few days.

Avalanche danger has been elevated from yesterday's LOW danger back up to MODERATE danger for today at all elevations due to uncertainty associated with a lingering persistent slab avalanche problem. Large destructive avalanches are possible again today, mainly in response to large triggers.

The avalanche danger is MODERATE in near and above treeline areas with LOW danger below treeline. Some lingering wind slabs may still exist and persistent slabs have become unlikely but not impossible.

MODERATE avalanche danger will exist at all elevations throughout the forecast region due to wind slab and persistent slab avalanche problems.  Large destructive human triggered avalanches could be possible today. 

CONSIDERABLE avalanche danger will exist at all elevations this morning due to wind slab and storm slab avalanche problems. The avalanche danger will increase to HIGH around midday as a second storm impacts the forecast area bringing blizzard conditions. HIGH danger will last through the night. Travel in avalanche terrain is not recommended.

LOW avalanche danger continues today for all elevations. Avalanche danger will increase significantly tomorrow at all elevations following the onset of new snowfall.

LOW avalanche danger will continue throughout the forecast region at all elevations.  Normal caution is advised.

LOW avalanche danger exists for all elevations today. While some difficult (but not impossible) to trigger wind slabs may still lurk in isolated near and above treeline terrain, human-triggered avalanches should remain unlikely in most places today.

MODERATE avalanche danger continues near treeline and above treeline in specific areas where blowing snow has formed new wind slabs. In wind protected areas below treeline, LOW avalanche danger exists.

Moderate Avalanche Danger will exist as continued high winds affect our region today and tonight.  Wind slab avalanches will be possible in near and above treeline terrain.  Low Avalanche Danger will exist in below treeline terrain.

The avalanche danger will rise to MODERATE during the day as new wind slabs form in near and above treeline terrain. Human-triggered avalanches will become possible. Overnight the avalanche danger will continue rising to CONSIDERABLE as wind slabs become larger and more widespread and storm slabs may become possible in below treeline terrain. 

LOW avalanche danger exists today for all elevations. A wind slab avalanche problem lingers near and above treeline. Human triggered avalanches are not impossible today.

Moderate Avalanche Danger will continue today due to a wind slab avalanche problem as gale force winds with the possibility of light snow returns to our forecast area.  Wind slab avalanches will continue to be possible in near and above treeline terrain.  Low Avalanche Danger will exist in below treeline terrain.  

MODERATE avalanche danger still exists in near and above treeline terrain, due to the possibility of lingering wind slabs. Human-triggered avalanches may remain possible today. Create a plan with safety margins to avoid the avalanche problems and maintain awareness of the conditions and terrain to stick to these safety margins while traveling in the backcountry.

The avalanche danger will remain LOW and avalanche activity will remain unlikely until it starts snowing this evening. Continue to use normal caution when traveling in the backcountry especially in areas where old firm wind slabs may linger. The avalanche danger will increase quickly as snow starts to accumulate tonight and could reach CONSIDERABLE during the night.

LOW avalanche danger continues for all elevations. Avalanche activity remains unlikely, but keep an eye out for isolated instability in any areas where drifting snow accumulates.

Moderate Avalanche Danger is expected today throughout the forecast region due to a wind slab avalanche problem.  Increased winds overnight and through today will make wind slab avalanches possible in near and above treeline terrain.  Low avalanche danger will exist in below treeline terrain.

Some wind slabs may exist on top of a buried weak layer in some areas in very wind-exposed near and above treeline terrain. The avalanche danger is MODERATE. Human triggered avalanches may be possible today.

Avalanche danger has risen to MODERATE danger near treeline and above treeline. Increased SW winds last night may have created new wind slabs and loaded the Dec 4 buried surface hoar layer. LOW avalanche danger exists below treeline.

Low avalanche danger is expected throughout the forecast area today.  Buried surface hoar exists under 3-5'' of storm snow from yesterday in many areas, but this small amount of additional load is not enough to warrant an avalanche concern at this time.  Normal caution is advised in the backcountry today.

The avalanche danger will remain at MODERATE today due to the possibility of unstable storm slabs still lingering in some areas. Significant uncertainty remains concerning these storm slabs. If any doubts exist about the stability of a slope, avoid it and move on to something lower angle with less uncertainty. New snow expected tonight may allow storm slabs to become more widespread.

MODERATE avalanche danger exists at all elevations today due to lingering wind slabs and possibly some remaining storm slabs. Human triggered avalanches will remain possible today. If any doubts exist about the stability of a slope, avoid it and move on to something lower angle with less uncertainty.

Areas of MODERATE avalanche danger exist near treeline and above treeline due to recently formed wind slabs. Below treeline, avalanche danger is LOW. Avalanche danger is expected to increase on Saturday at all elevations.

Early Season Conditions Update #2

Ongoing periods of precipitation are expected through the end of the week with several feet of new snow possible over the mid and upper elevations. Early season conditions exist along with some avalanche concerns. Daily avalanche advisories will begin on Nov 29 if the storms materialize as forecast. 

Stoked for winter. Getting things up and running.

Areas of MODERATE avalanche danger will exist today at all elevations as a loose wet avalanche problem occurs in response to daytime warming and snow surface melt. Avoid travel in or below avalanche terrain on slopes with marginally supportable to unsupportable wet snow conditions or on slopes where roller balls are occurring.

Periods of intense April sun this morning may cause enough warming for some small loose wet instabilities to form in isolated areas. MODERATE avalanche danger would result from this expected warming. If the forecasted cloud cover materializes sooner than expected, loose wet instabilities may be unlikely and less avalanche danger would exist. 

MODERATE avalanche danger exists at all elevations today due to rapid warming allowing loose wet avalanches to become possible and lingering wind slabs on wind-loaded slopes. The April sun will help destabilize the snowpack and conditions could change in a matter of minutes once the sun hits the new snow. Once any signs of warming snow or wet snow exist it is time to move to colder aspects, lower angle slopes, or switch an activity that does not involve snow.

MODERATE avalanche danger will exist for most of today at all elevations due to a loose wet avalanche problem. As new snowfall and wind impact the forecast area this evening, avalanche danger will increase to CONSIDERABLE danger near treeline and above treeline due to a wind slab avalanche problem.

The avalanche danger is MODERATE today. Rapid warming will make loose wet avalanches a more widespread problem today. In addition to the loose wet avalanches that are possible today, some small wind slabs may exist near ridgelines. 

The avalanche danger may rise to MODERATE during the day if enough warming occurs for loose wet avalanches to become possible. Once the storm arrives over the forecast area this evening the avalanche danger will quickly rise to CONSIDERABLE during the night due to newly formed wind slabs and storm slabs. Slab avalanche activity will be an issue tonight and slab instabilities will linger into tomorrow. 

Areas of MODERATE avalanche danger will exist today at all elevations. As last night's snow surface refreeze melts away, loose wet avalanches will become possible. When snow surface conditions become marginally unsupportable to unsupportable, avoid travel in or below avalanche terrain.

CONSIDERABLE avalanche danger exists at all elevations today. Natural avalanches are possible and human triggered avalanches are likely. Today's avalanche problems include widespread loose wet avalanches, possible deep slab avalanches, and maybe some wind slab avalanches at the higher elevations.  Avalanches that occur today could be large and destructive and could have severe consequences.

MODERATE avalanche danger will exist at all elevations due to loose wet avalanche problems becoming possible again today. Rain on snow and warm temperatures will allow this problem to continue through the night. Expect the avalanche danger to increase on Friday and Saturday as a strong storm impacts the area through Saturday.  

MODERATE avalanche danger will exist as daytime warming occurs and a loose wet avalanche problem develops at all elevations.  Unstable snowpack conditions can quickly form as snow becomes unsupportable and loses strength.

MODERATE avalanche danger will develop at all elevations as a loose wet avalanche problem forms in response to daytime warming. Timing for travel in avalanche terrain is critical. In wet snow conditions, slopes can switch from stable to unstable in as little as 20 minutes.

LOW avalanche danger this morning will quickly increase to MODERATE avalanche danger all elevations as the day warms up. Loose wet avalanche activity will become possible. 

MODERATE avalanche danger will continue today due to a loose wet avalanche problem at all elevations.  Wind slabs have become unlikely but not impossible today in isolated areas in near treeline and above treeline terrain.  Identify areas of unstable snow and avoid specific terrain features. 

MODERATE avalanche danger will exist at all elevations today due to a combination of loose wet and wind slab avalanche problems. The vast majority of any avalanche activity that occurs today is expected to be human triggered, but an isolated natural avalanche is not impossible today or tonight.

MODERATE avalanche danger exists in near and above treeline terrain where human-triggered wind slab avalanches are possible today. Deep slabs have become an unlikely but not impossible problem. 

The avalanche danger is HIGH in near and above treeline terrain and CONSIDERABLE in below treeline terrain due to a complex mix of heavy snow, rain, wind, and changing snow levels. Natural avalanches are likely today and human triggered avalanches are very likely. Today's avalanche problems include wind slabs, storm slabs, and possible deep slabs.  Wet snow instability cannot be ruled out. Travel in, near, or below avalanche terrain is not recommended.

MODERATE avalanche danger will continue today due to loose wet and deep slab avalanche problems.  Loose wet avalanche activity will be possible at all elevations as rapid warming occurs and rain becomes possible this afternoon.  Deep slab avalanches remain possible in isolated areas of the forecast region.  Avalanche danger is expected to increase over the next few days as a larger storm impacts our area.

MODERATE avalanche danger exists today at all elevations due to a combination of wind slab and loose wet avalanche problems. Backcountry travelers should not be surprised by the occurrence of a human triggered avalanche today. Areas of unstable snow will exist within surrounding greater areas of seemingly stable snow. Take active measures to avoid the specific terrain features where unstable snow is most likely to exist.
