After a completely calm two days since the new snow fell, the wind is just now beginning to stir. Expect to find freshly formed windslabs in the days to come.
The SW winds have blown for two days to affect ridgelines at treeline and above. Expect to find small, thin, freshly formed windslabs lurking near ridgelines and in the lee of open features. We would expect these to be more developed in the alpine.
The storm snow may now be hiding wind slabs in the lee areas of exposed features above treeline. New slabs will build with the 20-25cm of storm snow now available for transport. These will become larger and more easily triggered as the wind picks up.
Remember that previous West Winds had a strong effect on the current distribution of snowpack: fragile cornices and buried windslabs will complicate the picture and limit terrain choice as travelers look to avoid the persistent slabs

Moderate ridge top winds mainly from the West have developed thin new slabs at treeline and above these will continue to develop with the addition of new snow on Friday.
Fresh slabs can be found near ridgecrests at Treeline and in any lee features in the Alpine. Expect these to be sensitive to skier triggering especially while the temperatures remain warm Tuesday.
Buried windslabs are hiding under the recent low density snow at ridgecrests and lee features. New slabs will develop over Fri/Sat with NE winds and 20-30cm available for transport. This will be touchy until temperatures start to warm up next week.
New slabs have developed with the recent snow and NE winds, creating windslabs in places they may not usually be seen. As temperatures warm up and SW build more windslabs on Wed and Thur there will be a spike natural avalanche activity.
Steep, unsupported terrain is a likely trigger spot for these newly formed hard slabs that are found in all open areas at treeline and above.
These slabs are still a concern where the slope hasn't been sun effected. Steep, unsupported terrain is a likely trigger spot for these hard slabs that are found in shaded NE areas at treeline and above.
These slabs are a concern on shaded NE areas at treeline and above. Rain forecast for Sat will make these slabs more unstable and increase the avalanche danger. If these become rain soaked these could act as a wet slab avalanche.
Although thin in many areas, there are some significant slabs that have grown along the ridge crests. While warm temps limited growth at TL, be prepared for larger slabs above. New snow and continued west winds will continue to build these slabs.

Recently formed windslabs are now being buried by light snowfall
Previously formed windslabs are now difficult to detect as they were buried by the recent new snow.
Small surface wind slabs are still visible in isolated locations, while older large wind slabs are buried under a skiff of recent snow.
These may lie on a weak layer formed in dry weather during early January - suncrust on solar aspects, and facets / surface hoar all other aspects. Dig to see if this layer exists before committing to open slopes, as it may allow wide propagations.
These Wind Slabs are widespread, but generally stubborn at treeline. However, they may be touchy and propagate widely where they sit directly on a weak layer of suncrust/facets/surface hoar buried during early January. Avoid obviously loaded slopes.
These Wind Slabs are widespread in exposed areas, and may also be found in isolated locations below treeline. Avoid obviously loaded slopes.
Buried Wind Slabs are widespread in exposed areas, and are largest in the SW of the Park. These are hidden under recent snow, and touchier new Wind Slabs. Use extra caution on lee slopes - clues include cornices up above, and a deep snowpack.
While stubborn to trigger, windslabs have the potential step down to previously buried weak layers.
Buried wind slabs exist lee to previous SW winds. While stubborn, these wind slabs may propagate surprisingly far where they are hard, or sit on a hard surface. From Wednesday afternoon onwards, watch for for development of small new Wind Slabs.
Stubborn Wind Slabs exist lee to Westerly winds, and will increase in size and sensitivity by Saturday.

Flurries this weekend have the potential to be redistributed into fresh windslabs in isolated pockets in the alpine and at treeline.
At Treeline, wind slabs exist on the North and East sides of ridge crests. In open and Alpine terrain, their distribution is more random. Although the Wind Slabs feel stubborn to human triggers, be aware of a crust down 40cm that these could fail on.
