We have stopped issuing daily avalanche advisories for the 2015-2016 season. Avalanche advisories will resume in the fall of 2016.

Avalanche activity can and most likely will continue to occur this spring. This will occur with continued daily wet snow melt-freeze cycles and 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.

Moderate avalanche danger exists for all elevations and aspects on slopes 35 degrees and steeper due to wind slab and loose wet avalanche problems. Locations in the northern portion of the forecast area will be most prone to these avalanche problems today. Locations in the southern portion of the forecast area where little to no new snow accumulated over the past 36 hours will have more limited loose wet avalanche problems today and no wind slab avalanche problems.

MODERATE avalanche danger could exist on NW-N-NE-E-SE aspects due to a combination of wind slabs in near and above treeline areas and loose dry avalanches. Today's avalanche activity should remain small due to the amount of new snow, but some avalanches could cause problems for backcountry travelers especially north of Tahoe City or near terrain traps. If the sun breaks through the clouds, today some small isolated loose wet avalanches could occur on the near and below treeline SE-S-SW aspects

LOW avalanche danger exists this morning. Some slopes steeper than 35 degrees on the E-SE-S-SW-W aspects may see enough sunshine and warming for the avalanche danger to increase to MODERATE due to the possibility of loose wet avalanches. Loose wet activity may also become possible on some NW-N-NE aspects in near and below treeline terrain if the sun hits those slopes. If more cloud cover persists today, loose wet snow will remain more isolated since less melting will occur.

Loose wet avalanches will remain possible all day today on slopes steeper than 35 degrees on all aspects and elevations. These loose wet avalanches will keep the avalanche danger at MODERATE for today.  Some of the loose wet avalanches could involve enough snow to threaten backcountry travelers.

Moderate avalanche danger could exist on NE-E-SE-S-SW-W aspects near and above treeline due to newly forming wind slabs.  These wind slabs should be limited mainly north of Hwy 50 where we received more snow in the last 24 hours.  Loose wet avalanches are unlikely today but could occur if we receive large periods of sun and less cloud cover than forecasted.  Adjust terrain choices and route selection according to localized conditions.

Snowfall amounts and avalanche danger will vary greatly around the forecast area today. Adjust terrain choices and route selection according to localized conditions. Near and above treeline on NW-N-NE-E-SE-S aspects on slopes 35 degrees and steeper, avalanche danger could range from LOW danger to CONSIDERABLE danger based on the size of newly formed wind slabs.

Careful snowpack evaluation, cautious route-finding and conservative decision-making are essential. Identify where wind slabs and storm slabs exist and avoid them and their run out zones.

LOW avalanche danger exists this morning while the snowpack remains frozen. As the day warms up and last night's refreeze melts, pockets of MODERATE danger will quickly form slopes steeper than 35 degrees on E-SE-S-SW aspects due to the possibility of loose wet avalanches. Small human triggered roller balls, pinwheels, and point-releases should comprise most of the loose wet activity, but some loose wet avalanches could involve enough snow to cause problems for backcountry travelers.

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.

This morning the avalanche danger is LOW on all aspects and elevations. Some pockets of MODERATE avalanche danger may form below 9000 ft. on sun-exposed SE-S-SW aspects steeper than 35 degrees as the day warms up, and some small loose wet snow instabilities become possible.

CONSIDERABLE avalanche danger exists in near and above treeline terrain on NW-N-NE-E-SE aspects on slopes steeper than 35 degrees due to newly formed wind slabs. MODERATE avalanche danger exists elsewhere. The largest wind slabs will exist above 8700 ft. where more snow has accumulated. Human triggered wind slab avalanches are likely today, and some small sluffs may be possible.

Despite becoming increasingly difficult to trigger,  human triggered avalanches remain possible on some W-NW-N-NE-E-SE aspects at all elevations on slopes steeper than 32 degrees due to persistent slabs and old wind slabs. The avalanche danger is MODERATE today, but it will quickly increase to CONSIDERABLE due to added weight on the persistent slabs and new wind slabs resulting from more snow and wind impacting the region tonight and tomorrow. Some natural avalanche activity may start to occur during the night.

Even though avalanches have become more difficult to trigger, human triggered avalanches remain possible on some NW-N-NE-E-SE aspects at all elevations due to lingering persistent slabs and wind slabs. The persistent slabs could occur on slopes steeper than 32 degrees, while the wind slabs would be more problematic on slopes steeper than 35 degrees.
