LOW avalanche danger exists this morning. As the day warms up, some pockets of MODERATE danger may form on sun-exposed SE-S-SW aspects steeper than 35 degrees up to 9500 ft. due to the possibility of some small loose wet snow instabilities like pinwheels, roller-balls, and point release avalanches. Most of these loose wet snow instabilities should remain small and isolated, but a few could entrain enough snow to create issues for backcountry travelers on slopes that experience the most warming.

MODERATE avalanche danger exists on NW-N-NE-E-SE aspects steeper than 35 degrees in near and above treeline terrain due to new wind slabs. Some isolated pockets of MODERATE danger may exist on NW-N-NE aspects steeper than 35 degrees at all elevations north of Emerald Bay due to storm slabs forming above a lingering persistent weak layer. Evaluate the snow and terrain carefully before committing to a slope instead of letting the excitement of early season snow lead to poor decision making.

LOW avalanche danger will persist on all aspects and elevations during the day today. Some unstable snow could still exist on isolated terrain features due to the presence of lingering persistent weak layers. The avalanche danger will increase quickly tonight and rise to CONSIDERABLE as new wind slabs and some small storm slabs form overnight. These avalanche problems mean that careful snowpack evaluation, cautious route-finding and conservative decision-making will be essential tomorrow (and tonight).

The avalanche danger remains LOW on all aspects and elevations. Avalanches remain unlikely but not impossible. Some unstable snow could still exist on isolated terrain features due to the presence of lingering persistent weak layers. The shallow snowpack means that numerous rocks, stumps, logs and other hazards remain exposed or barely covered.

LOW avalanche danger continues for all elevations and aspects. The potential exists for the unlikely triggering of small avalanches in isolated areas. Continue to use accepted best practice travel techniques while traveling in or below avalanche terrain. It is still early season and the snowpack is relatively shallow. Numerous barely covered rocks, stumps, logs, and other hazards exist.

LOW avalanche danger exists for all elevations and aspects. Small avalanches in isolated areas are quite possible given the current snowpack structure. Triggering is unlikely, but far from impossible. This fits the definition of LOW avalanche danger. It is a myth that LOW danger equals no danger. Exercise best practice backcountry travel techniques and manage terrain wisely.

MODERATE avalanche danger exists on all aspects in near and above treeline terrain on slopes 35 degrees and steeper due to presence of old hard wind slabs and smaller newly formed wind slabs. Human triggered avalanches remain possible today. Loose dry sluffs may remain possible on steep, sheltered, lower-elevation slopes as well. Evaluate the snow and terrain carefully before committing to a slope instead of letting the excitement of early season snow lead to poor decision making.

Avalanche danger remains LOW for all elevations and aspects. Triggering is unlikely but certainly not impossible given the current snowpack layering. Per the definition of LOW danger from the North American avalanche danger scale, small avalanches may still occur in isolated areas or extreme terrain during LOW danger. Use caution and watch for unstable snow on isolated terrain features when traveling in the backcountry. Shallow snow cover over rocks, stumps,and logs remains a significant hazard.

Pockets of MODERATE avalanche danger exist above treeline on all aspects on slopes 35 degrees and steeper due to lingering wind slabs. Near treeline and below treeline avalanche danger is LOW on all aspects. Isolated areas of unstable wind slab may remain near treeline, especially in complex terrain. LOW danger means that human triggered avalanches have become unlikely and areas of instability are isolated, not that avalanches will not occur.

Early Season Conditions Update #1

While overall snow depth remains shallow, wind slabs and basal facets are starting to show themselves as potential problems. At this point, early season forays into or below snow covered avalanche terrain without deliberate, educated snowpack assessment and companion rescue equipment is foolhardy. Daily avalanche advisories will resume once the snowpack becomes deep enough for over snow travel in widespread areas. Until that time, occasional updates to this page will occur as conditions warrant.

We have stopped issuing daily avalanche advisories for the 2014-2015 season due to significantly warmer than normal temperatures and below average precipitation this winter. Avalanche advisories will resume in the fall of 2015.

Avalanche activity can and most likely will continue to occur this spring as additional storm cycles impact the forecast area. Continue to monitor changing conditions and use caution when traveling in the backcountry. For general spring avalanche information please read the full spring avalanche statement.

Avalanche danger should remain LOW for all elevations and aspects again today. Some small loose wet snow instabilities could still occur on some steep slopes today on any aspect where snow cover still exists. Sunny E aspects represent the most likely places to find wet snow. While loose wet snow instabilities should remain minor inconveniences in most places, they could become more problematic near terrain traps (like cliffs) where the terrain can magnify the consequences of any size avalanche.

Areas of MODERATE avalanche danger will form today on slopes 37 degrees and steeper in response to daytime warming. Widespread loose wet instability in the form of roller balls, pinwheels, and loose wet avalanches not large enough to bury or injure a person are expected. Areas of MODERATE danger will be most widespread NW-N-NE-E aspects where snow cover existed prior to the last storm and may form in very isolated areas on SE-S-SW-W aspects.

The avalanche danger should remain LOW in most places today. Small human triggerable wind slabs may linger on isolated terrain features on previously wind loaded NW-N-NE-E-SE aspects in near and above treeline terrain. These terrain features could include extreme or complex terrain, wind loaded slopes above cliffs, other unsupported slopes, couliors, and gullies. If enough warming occurs today, some small isolated loose wet snow instabilities may also form.
