Uncertainty about wind slabs in the ALP is a concern. Suspect that the cooling temperatures and high pressure with little wind is quickly tightening these in, but few reports to verify.

The windslab problem is not a huge problem right now but if the weather forecast is accurate they will likely develop at/near ridgecrest as temps warm and winds pick up. A bit of new snow will be a lesser contibuting factor.

A weak interface is buried about a metre down. A surface avalanche stepping down, cornice fall, or the weight of a person from a thin-spot trigger point could trigger it.
Stiff windslabs can be found along ridgelines and in gullied terrain. The entire snowpack is likely to be involved in any avalanche that occurs on this layer.
New storm slabs are forecast to develop overnight.&nbsp;
New storm slabs are developing. Forecast strong Westerly winds may cause these slabs to be very easy to trigger.
The added load from the new snow may overload the deeply buried weak layer of early season crust. Northerly aspects in the alpine are the most suspect areas for this crust to become reactive.
Forecast snow and wind are expected to continue to develop a very touchy storm slab. Watch for areas that have already released re-loading from heavy snowfalls.
New storm slabs may release naturally or be triggered by light additional loads like skiers/riders. These storm slabs may be sitting on a layer of surface hoar on Northerly aspects, or on a melt/freeze crust on Southerly aspects.
I have this problem on all aspects, because we do not have many reports from this region. Dig down and find out if this deeply buried weak layer is in your area. Let us know what you find.
New storm slabs are expected to be easy to trigger with light additional loads like skiers/riders. New snow depths may vary greatly by elevation, with deep pockets of wind transported snow in the alpine.
Recently loaded lee slopes may be particularly touchy. If triggered they have potential to initiate a larger avalanche on a crust/facet layer buried deep in the snowpack.

High winds accompanying the recent snowfall will have produced wind slabs at tree line and above. Use caution venturing into wind loaded lee slopes
Touchy storm slabs exist with the potential to create large avalanches. Storm slabs may be more reactive on slopes affected by wind, or in areas where they overlie surface hoar. Sluffing may also occur where new snow is unconsolidated.
Loading from the recent storm may reactivate persistent weaknesses buried in the mid and lower snowpack. If triggered, avalanches on these layers would be large and destructive.
Variable amounts of new snow are probably gaining strength. The new slab is likely to be most reactive in exposed high elevation terrain where it exists as a wind slab.

Avalanches initiated in the upper snowpack are likely to step down to the basal October crust and involve the entire winters snowpack.
Storm slabs are beginning to develop with the arrival of new snow and strong winds over the next 24hrs. Snowfall amounts so far have been much less than expected, so this problem is not yet a major concern. However the situation could rapidly evolve.
Sluffing is occurring in steep Alpine terrain.
New wind slabs may form on South and West aspects at all elevations in response to strong outflow winds this week. It may also be possible to trigger older wind slabs on exposed North and East aspects near ridgetop.
New storm snow may not bond well to the underlying surface, which may include surface hoar or a sun crust. Strong northerly winds may form touchy new wind slabs in exposed South to West facing terrain.
The October rain crust and the early November surface hoar are lurking deeper in the snowpack. Smaller storm avalanches could step down to one of these layers creating a large full-depth avalanche.
Strong and variable winds have formed touchy wind slabs on a variety of aspects in exposed terrain. Outflow winds this week could redistribute new snow and create dense wind slabs on West and South aspects.
Suspect that there is a touchy to very touchy storm slab above the recent surface weakness. No information about how deep this storm slab is or how variable it is.
Deep storm slabs are releasing naturally from steep terrain, and are very easy to trigger on all aspects and at all elevations. Triggering slopes from adjacent terrain is a concern due to the buried surface hoar and crusts beneath the storm snow.
The new storm slab may be up to 50 cm deep in some parts of the region. This storm slab may release naturally, or be triggered by light additional loads like skiers/riders. Travel on adjacent terrain may trigger avalanches.
If deeply buried weak layers are triggered, expect very large destructive avalanches.
This potent new storm slab will be tricky to manage as it overlies a variety of weak surfaces. The new snow may also exist as a windslab in exposed terrain. Expect touchy conditions for the forecast period.
Loading from the recent storm may reactivate persistent weaknesses buried in the mid and lower snowpack. If triggered, avalanches on these layers would be large and destructive.
The cooling trend should help stabilize the recently developed storm slab. Forecast northerly winds, however, may redistribute loose surface snow into new windslabs on south-facing slopes.
A newly formed storm slab may be particularly reactive in wind-affected terrain. Watch for ongoing windslab formation with strong northerly winds forecast for the next few days.
The storm slab problem will be heightened in the southern portion of the forecast region where they received 40cm of new snow. To complicate the scenario, a forecast shift in wind pattern will likely create fresh wind slabs on south facing slopes.
The added load from the new snow may be enough to tip the scale and wake up the deeply buried October crust weak layer. This layer is most likely a problem for northerly aspects in the upper treeline and alpine.
Cold temperatures will likely allow the storm slab overlying buried weaknesses to persist for some time. To complicate the scenario, a shift to northerly winds may have deposited wind slabs on south facing slopes.
The weight of the new snow may be enough to overload buried weak layers found in the mid to lower snowpack. The weight of a smaller storm snow avalanche may also have the potential to step down to one of these deeper layers.
Up to 50 cm of storm snow sits on a recently buried surface hoar layer or sun crust. Be particularly cautious in areas that have been wind affected forming a slab.
Northerly outflow winds have likely created new wind slabs in exposed lee terrain at all elevations. These could remain sensitive to rider triggering throughout the week.

New wind slabs are likely in exposed lee terrain at all elevations from northerly outflow winds. These wind slabs may be in unusual areas and could be triggered by the weight of a rider. 
Northerly outflow winds have likely created wind slabs in exposed lee terrain - in areas that may be somewhat unusual. Rider triggering is possible throughout the week.&nbsp;
Suspect that the storm slab has become stubborn to trigger. The storm slab is sitting above the recent surface weakness. No information about how deep this storm slab is or how variable it is.
Storm slabs may continue to be triggered by human activity where the new snow is sitting on a weak layer that was recently buried. Storm snow slabs are up to 70 cm deep and may result in large avalanches if triggered.
The deeply buried early season crust may be reactive to the added load of storm snow, the weight of large triggers like snowmobiles or a group of skiers, or from storm snow avalanches in motion.
Storm snow avalanches are becoming more stubborn to trigger. As the storm snow settles into a cohesive slab or is transported into a wind slab, wider fracture propagations resulting in larger avalanches are a concern.
A settling storm slab overlies various buried weaknesses; surface hoar on shaded slopes and and a melt-freeze crust on solar facing slopes. In areas where the surface hoar overlies a thin melt-freeze crust the slab above may be particularly touchy.
The recent storm snow has been redistributed by northerly winds into wind slabs on south facing slopes. Cold temperatures may allow these wind slabs to persist.
The deeper weaknesses found in the mid and lower snowpack could be triggered by the weight of a rider, particularly in a areas where the snowpack is shallow. Additionally, the weight of a surface avalanche could also trigger these deeper layers.
This potent new storm slab will be tricky to manage as it overlies a variety of weak surfaces. A conservative and investigative approach is required for safe mountain travel.

Only for the N sections where it is suspected to be rounding and gaining strength. Probably will get flushed out down south with this storm.
Skier triggerable windslabs are being encountered as one moves into more treeline or wind affected features.&nbsp; Two recent close calls were observed each around 2200m.

Windslabs are present at treeline and alpine elevations. The thickness of these slabs vary depending on where you look in the terrain. The reactivity of these slabs is still a concern.
Still the main concern out there right now. The surface windslabs are still prone to human triggering in the right piece of terrain. The potential for large avalanches is still out there on this layer.
Wind slabs continue to grow on lee slopes at tree line and above. In some areas these slabs may be up to one metre thick. Warm temperatures may result in loose wet avalanches on southerly aspects, or cornice falls, triggering these wind slabs.
Storm snow may not have bond well to the surface hoar and melt-freeze crusts that developed before the storm.  Forecast warm temperatures may result in easier triggering of these slabs
This problem is more likely in areas that had a shallow snowpack during the cold arctic outbreak. Loose wet avalanches or cornice falls may trigger deeply buried weak layers resulting in large destructive avalanches.
Warm temperatures may significantly change the nature of the snow pack. Slopes exposed to strong solar radiation may become weak and easily triggered by rider activity. Special concern should be given to shallow snow pack areas.
Dense storm slabs above this SH layer will likely now be hard to trigger, but if triggered may produced large destructive avalanches.
A cornice failure could trigger deeply buried weak layers buried near the ground. This is more likely in areas that had a shallow snowpack during the cold arctic outbreak.
Surface hoar and near-surface facetting from cold temperatures are beginning to erode the wind slabs. In some areas, however, winds are continuing to build wind slabs. Be extra cautious in areas of shallow snow pack with wind slabs on top.
Storm snow and hard wind slabs have been added to the load above buried weak layers. Deeply buried weak layers may become harder to trigger, but the consequences could be very large destructive avalanches.
Cornices may become weak and fail naturally with the strong solar radiation and warm alpine temperatures. Cornice falls are a large load that could trigger buried persistent weak layers on slopes below, resulting in large and destructive avalanches.
The chance of triggering a deep persistent slab is greatly reduced. However if you did trigger such an avalanche, the consequences would be great. The most suspect slopes would be thin or variable alpine start zones on steep convex slopes.
Although deep persistent slab avalanches have become less likely, the consequences of a release would be severe. Possible triggers include cornice fall, rapid temperature change or a heavy load over a thin spot.
It's getting to the point where it's difficult to trigger an avalanche in most of the region, but it's certainly not impossible.&nbsp; Be wary of steep faces receiving direct sun and do your best to avoid potential weak areas as listed below.

30-55 cm of recent snow and strong SW winds have built touchy wind slabs on lee slopes. Storm slabs at treeline and below may be reactive to rider triggers. Whumpfing, cracking and avalanches are direct indicators of a buried weak layer.

Forecast new snow and strong winds are expected to continue to add a new load to the storm slab. Natural avalanches and very touchy sensitivity to human triggers may result from this added load.
Variable new snow amounts across the region have developed a storm slab that is between 40-70 cm. The storm slab may be triggered by light additional loads or remote triggered from adjacent terrain.
There are several buried crusts and or surface hoar layers that developed in the end of January and during the cold weather earlier this month. Avalanches releasing on these layers may be large with serious consequences.
The new snow is expected to continue to be touchy to any additional load. Small avalanches in motion may step down to the bottom of the nearly metre deep storm slab. Conservative terrain selection with no overhead hazard is required.
The crust and facet layer that developed during the cold weather at the beginning of the month is now down about 90 cm. Avalanches that release on this PWL are expected to be less frequent but higher consequence.

Strong south winds over the weekend have deposited deep wind slabs in lee terrain features. Forecast winds are to shift from north to south by mid-week, potentially depositing fresh wind slabs on all aspects.
A recently buried weak layer composed of a melt-freeze crust/facets and surface hoar is creating touchy conditions. This layer, down 30-50cm appears most reactive further south, responsible for several recent remotely triggered avalanches.

Forecast new snow and wind are expected to add to the deep storm slab above the early February weak layer. Expect increased sensitivity to human triggers and another round of natural avalanche activity.
Forecast new snow and strong winds are expected to add to the load of recent storm snow resulting in natural avalanche activity. Light additional loads may propagate long fractures into remote terrain.
The early February crust /facet layer is now down over a metre and continues to be reactive. Storm snow avalanches in motion may step down to this widespread weak layer. Expect long fracture propagations across terrain boundaries.
More new snow and wind are forecast overnight. Expect very touchy storm slabs that may step down to the persistent weak layer that is about a metre deep. Natural avalanches and remote triggering are likely.
Forecast new storm snow may over load the persistent weak layer resulting in very large avalanches. Storm snow avalanches in motion may step down to the buried weak layer.
The slab on top of this layer is becoming stiffer and more susceptible to widespread propagation across terrain .
The basal weakness remains, and incoming snow and wind may lead to a re-awakening of this problem.
Close to a metre of highly reactive storm slab is now sitting on a variety of weak layers, facets, surface hoar and decomposed wind slab. Significant potential for remotely triggering an avalanche below or adjacent to start zones exists.
Up to 60cm of storm snow has settled into a reactive storm slab that lies over a combination of surface hoar, facets, and wind slabs. Wind slabs above and below tree line are a major concern. Remote triggering is probable in even moderate terrain.

The windslabs from last week have been downgraded to persistent slabs. The reason for this is the slow bond and the general nature of the Feb 11th layer. This avalanche problem will be on the radar for some time.
A few more cm of new snow and continued strong winds are forecast. Expect natural avalanche activity, long fracture propagations and remote triggering to continue.
A little bit more new snow and continued strong winds are forecast. Expect natural avalanche activity to continue, as well as long fracture propagations and remote triggering.
The persistent slab is over a metre deep and continues to be very touchy to any additional load. Continued wind loading, storm slab avalanches or cornice falls in motion, and triggering from adjacent terrain are all concerns.
The natural avalanche cycle is expected to continue with another load of new snow and wind added to the storm slab.
Expect the deeply buried weak layer to continue to produce very large and destructive avalanches. Each load of new snow adds to the storm slab above the weak layer.
Large avalanches are still running naturally and remote triggers are being reported.  It's not necessary to be on a big slope to trigger it, triggering may be accomplished by reasonable proximity to the slope. Time to scale back plans for big rides.
