Use caution in thin snowpack areas averaging 150cm or less. In these areas the basal snowpack layer of depth hoar and facets remains weak, and the mid and upper snowpack is thin enough to allow for triggering of the deep persistent layer.
The snow on slopes facing the sun will become moist this afternoon.  Use caution on steep terrain and around terrain traps.
This layer has become mostly dormant, but skier triggering may still be possible in shallower snowpack areas.
This problem exists with day time warming and especially on solar aspects.
This problem will require a large trigger, thin spots or rapid day time warming.

This layer has become mostly dormant, but skier triggering may still be possible in shallower snowpack areas.
This problem will increase with day time warming and solar input, Travel early when the snowpack is frozen on solar aspects, and avoid during the heat of the day.
This problem will require a large trigger, thin spots or rapid day time warming.
Use caution in thin snowpack areas averaging 150cm or less. In these areas the basal snowpack layer of depth hoar and facets remains weak, and the mid and upper snowpack is thin enough to allow for triggering of the deep persistent layer.
Strong spring sun paired with rising freezing levels will produce loose avalanches. Start the day early and be mindful of what is above you.
Moist snow has the potential to release due to the heat of the sun, entraining slopes below

Moist snow has the potential to release due to the heat of the sun, entraining slopes below
As the snow falls, it will be sitting on a variety of surfaces, from Melt freeze crusts to Scoured wind hammered and sastrugi. The bond will depend on the temperatures during the storm.
This problem will require a large trigger, thin spots, increased loading or rapid day time warming.

Strong possiblity of rain overnight and into the morning at lower elevation areas below 2000m
This problem will require a large trigger, thin spots, increased loading or rapid day time warming.
Incoming snow and moderate to strong SW winds Monday will create fresh wind slabs in lee areas at treeline and above. These will be possible to trigger by skiers. Avoid wind loaded areas in steep terrain, especially in thin snowpack areas.

Use caution in thin snowpack areas averaging 150 cm or less. In these areas the basal snowpack layer of depth hoar and facets remains weak. This has been unreactive for the last week but is still a concern in steep terrain.
New snow paired with moderate west winds will form windslabs. The timing of the incoming precipitation is uncertain so keep a close eye on what the weather is doing over the next few days.
Sunny skies on Thursday means loose avalanches on solar aspects. Watch for the obvious signs of moist surface snow and pinwheeling, and avoid overhead hazard, especially where cornices are involved (think Mt. Bertha).
Possibility new snow with varied consistency depending on elevation. Slabs may be limited to TL elevations but depends on condition of old surface, which is quite varied across the region.
This problem will require a large trigger, thin spots, increased loading or rapid day time warming.

10-15cm of new snow in the past 48 hrs appears to be bonding well to layers below. At ridge tops and on solar slopes, where crusts may be buried, this problem is of most concern.
The mid snowpack is consolidating and offers bridging strength over a weak&nbsp; base. Caution is needed in areas where the snowpack is thin.  Collapsing cornices may trigger this weakness unleashing large avalanches.
