The recent 25cm of snow will be reactive for a few days until it has had time to settle. This problem was active on Monday. More snow starting on Tuesday extending into Thursday may add to this problem.
The 25cm of new snow is enough to create loose avalanches in steep terrain or gullies. Extra heads up for ice climbers.
Sunday's storm had strong SW winds. Expect windslabs to have developed particularly on lee aspects.
30 - 60 cms of snow from the last storm has settled into a slab that overlies the Halloween crust/ facet interface. A natural avalanche cycle occurred on this layer on Sunday and Monday with avalanches to size 3, mostly starting in the low alpine.
Strong SW winds on Sunday created windslabs up to 1 meter thick in exposed alpine areas. If triggered, these will likely step down to the Halloween crust/ facet layer, creating a much larger avalanche.

The Halloween crust, while stubborn is active given the right location.  This layer can be found down approx 100cm and is a developing problem.
Expect incoming snow to overload the Halloween crust.  This may produce our first cycle of large avalanches this season.
Total new snow accumulations may reach 60cm by Friday.
The distribution of this problem will be tied to the freezing levels.  Rainfall may occur up into the alpine in the coming days.
This is an active avalanche problem and is the main reason people should avoid all avalanche terrain for Wednesday and Thursday. The problem exists in most terrain and will become overloaded with the incoming storm. Watch overhead hazard.
Winds up to 100 km/hr are forecast for Wed and Thurs which will load the new snow onto leeward aspects. Windslabs should be expected near all ridges and gully areas and can be expected to become large once triggered.

The distribution of this problem will be tied to the freezing levels. Rain is expected to continue near and below treeline tonight and tomorrow morning.
Intense loading of start zones combined with warm temperatures and significant rain or snow fall, has created touchy storm slabs.
Rain penetrating the upper snowpack can percolate down to the halloween crust, awakening this layer.
We have observed many loose wet avalanches over the last 24 hours. This trend will continue until the temperatures cool significantly.
This is an active avalanche problem that has become over loaded. It is the main reason people should avoid all avalanche terrain. Watch overhead hazard, avalanches will run further than expected incorporating slushy wet snow.

Dry surface snow is insulating a rain-saturated wet slab that extends almost to the ground. This is a snowpack weakness that will only heal with cold. Given the mild weather forecast, this layer is expected to persists for several days.
This is a complex problem which is hard to assess and predict. Give yourself a wide margin and make conservative terrain choices.
While the snow became soaked at lower elevations and has a thick refrozen surface crust, the new crust gets thin above 2400m and it is uncertain whether the deeper Halloween crust will continue to be reactive. A conservative approach is recommended.

New snow and southerly winds have created reactive storm slabs. Slabs will be well-formed on lee features when wind has contributed to loading. These slabs are touchy and sensitive to human triggered loads as well as natural inputs like wind and sun.
Sun crusts are buried 30-60 cm on steep solar aspects. This interface provides a smooth bed surface and may contribute to larger than expected avalanches. It is possible for storm snow avalanches to trigger this lingering problem.
A cold, facetting, and structurally weak slab up to 80cm thick overlies faceted crystals (well developed in shallow areas). Low elevations will present as a loose dry avalanche problem.

20-30 cm of snow in the last 24hrs has been sluffing naturally in steep terrain and is reactive to skiers. Wind, warm temps or sunny breaks will also increase the likelihood of this. Avoid steep confined terrain until the new snow settles and bonds.
20-30 cm of new snow is forming a soft slab and has been reactive to skier triggering. Places where this slab sits over a melt freeze crust may be the most likely to fail, but all steep terrain will be suspect for the next day or two.
Areas with deeper storm snow amounts are sluffing easily. This is a good time to avoid steep gullied terrain where even a small avalanche will gain mass quickly. Wind, warm temps or sunny breaks will also increase the likelihood of this problem.
In places where the storm snow is deepest, a soft slab has formed that remains reactive to human triggering. Monitor the storm snow amounts frequently, and use caution on larger slopes if a storm snow slab is present.

A slab up to 80cm thick overlies: weak faceted crystals (well developed in shallow areas), surface hoar (at, and just above treeline), and sun crusts ( on steep S and W aspects). Faceting has reduced slab strength below treeline and in shallow areas.
With some new snow and stronger SW winds the wind slabs have become a bit more reactive over the past 24 hrs, especially where present over a buried sun crust.
25cm of snow in the last 24hrs with strong to extreme winds has created widespread storm slabs on all aspects at Treeline and in the Alpine. Expect the strong winds to have scoured south aspects &amp; created firm windslabs on North facing slopes.
Overloaded and under tension, new and buried windslab in the Alpine and TL will be sensitive to further loads, like more wind, more snow, and riders.
A slab up to 1m thick overlies: weak faceted crystals (well developed in shallow areas), surface hoar (at, and just above treeline), and sun crusts (on steep S and W aspects). Faceting has reduced slab strength below treeline and in shallow areas.
Gusty winds and new snow have formed touchy soft slabs that are reacting easily to skier traffic and starting to fail as natural events. Watch for another pulse of snow to either contribute to these slabs or potentially hide them.
While it has been a few days since there has been any confirmed events directly associated with the March 15 crust, other crusts have now become buried in similar locations. Forecasters still voice caution with all of these potential sliding layers.

Over 30cm in last 48hrs initially accompanied by strong to extreme winds has created widespread storm slabs on all aspects at Treeline and in the Alpine. Expect the strong winds to have scoured S aspects &amp; created firm windslabs on N facing terrain.
The forecast calls for cloudy with sunny periods. If the sun does decide to make an appearance today solar radiation may initiate loose wet slides on steeper Southerly aspects. Rain possible later today will also destabilize surface layers.

A slab up to 1m thick overlies: weak faceted crystals, and sun crusts (on steep S and W aspects). This problem has been associated with large triggers like cornices and the subsequent avalanches are proving large and destructive.
Loose wet slides can be expected as daytime warming pushes freezing levels upwards of 1800m. Expect surface snow layers to be moist and reactive on convexities and unsupported features treeline and below this afternoon.
Over 30cm in last 72hrs initially accompanied by strong to extreme S'ly winds has created storm slabs on all aspects at and above Treeline . Wind effect may have hardened the slab on alpine lee slopes. Today's snow may mask this problem.
New snow will bury windslabs in the Alpine and TL, these are overloaded and under tension, and remain sensitive to light loads.
Large cornices in all areas of the bulletin region. When failing these are triggering persistent instabilities and the subsequent avalanches are proving large and destructive.
A slab up to 1m thick overlies: weak faceted crystals, and sun crusts (on steep S and W aspects). This problem has been reactive recently in North facing terrain.
20-50 cm of storm snow has fallen over the past few days with the greater amounts near the divide, and more is expected on Tuesday. This is settling quickly but wind loaded areas and steep terrain will be suspect for the next couple days.
While it has been several days since there have been any confirmed events directly associated with the March 15 crust, other temperature crusts have now become buried in similar locations and are providing a good sliding layer for the new storm snow.

While it has been several days since there have been any confirmed events directly associated with the March 15 crust, other temperature crusts have now become buried in similar locations and are providing a good sliding layer for the new storm snow.
Over 40cm in last 72hrs accompanied by mod to strong winds has created storm slabs on all aspects at and above treeline . Wind effect may have hardened the slab on alpine lee slopes. Today's snow may mask this problem.
