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.

Extreme southerly winds accompanied yesterday's storm and created reactive wind slabs. This problem is specific to the alpine due to intense rainfall and warmer temps at lower elevations during the storm.
This layer was awakened by heavy loading during the last storm. Although natural avalanche activity has subsided, this crust remains a concern due to its persistent nature in the snowpack. Human triggering is certainly possible.
Terrain at higher elevations did not get the rain from Thursdays storm and the halloween facets/crust will still be reactive to human triggering with a thicker slab on top. 
There has been lots of new snow up high over the past few days, and some wind slabs have been noted on lee aspects that in the short term may still be reactive. So far, reports from the field have reported these wind slabs to be &quot;stubborn&quot; in nature.

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.
Extreme southerly winds accompanied the November 22nd storm and created reactive wind slabs. This problem is isolated to leeward pockets in the alpine due to intense rainfall and warmer temps at lower elevations during the storm.
This is a complex problem which is hard to assess and predict. Give yourself a wide margin and make conservative terrain choices.
Be wary of areas where new snow transport has created pockets of windslab. Watch for sudden changes in texture and hardness. Typically occurring on lee aspects but may be influenced by local terrain.
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.
Given the amount of snow and wind that the alpine has seen in the last several days, a few reactive windslabs can likely still be found. Expect the incoming storm to create touchy new slabs as it passes.

Increasing West winds have moved new snow around in the alpine forming small slabs in lee areas. Watch for these in the high alpine, especially in steep unsupported terrain where skier triggering may be possible.
Isolated storm slabs could be found at ridgetop or features exposed to the wind. Solar radiation will trigger loose dry avalanches on steep sunny slopes and cliffs. These &quot;sluffs&quot; could trigger a soft slab or step down to a persistent weak layer.
Several sun crusts are buried within the top 50 cms on steep solar aspects. These layers have the potential for human triggering, dig down and assess the snowpack before committing to the line.
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.

rising freezing levels and large triggers like cornice failures may wake up deeper slab instabilities
Avoid steep gully areas and any sun exposed faces or overhead terrain - it will avalanche when the sun hits it. Stick to shaded terrain and look way overhead to make sure nothing big is hanging above you - things are falling off these days.
Hot weather means cornice season, and this is the time when large mature cornices begin to fall off and the mountain sheds its snowpack. On ridges stay well away from cornices (they can reach back and get you), and avoid traveling under them.

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.
