While not widespread, or thick it can be found on steep terrain. Beyond the predictable crust formation, we still have those pesky windslabs from the last couple of wind events. These range in hardness, but unfortunately seem to be everywhere in the alpine. And of course, we have the lower 2/3's of the snowpack that is still a delicate combo of facets and depth hoar.

The lack of support within the snowpack is preventing any sort of anchoring. Treeline has a similar issue, only the wind slabs are thinner and not as widespread. The treeline slabs may be even touchier because of their thin nature and shorter recover (re-freeze) time at night.</span></p><p class="p_CC664AAA"><span class="s_AA239A9B">To share an opinion, this year's snowpack has a character that we haven't seen before.

Expect this new snow to slide and entrain all of the storm snow, especially on solar aspects. . This new snow has fallen on top of a previous melt freeze crust that developed during last weeks heat wave. The main concerns at this time is the new snow sliding on solar aspects that are overlying the previous melt freeze crust as well as concerns associated with the deep persistent weak base. The freezing level on Thursday climbed to 2300m with some moist snow being found below this elevation. Untracked areas at treeline and below are weak isothermal. In these Spring conditions, the avalanche danger rating can deteriorate rapidly, especially with solar input.</span></p>

The deep persistent weak facets will be with us until the snow is gone.  Be sure to asses this layer as you travel.  Some good corn is out there if you can get the timing right!!&nbsp; Start Early and be home early and avoid the heat of the day</span></p>

Day time high, quality of freeze overnight, aspect and influx of new load from snow or rain. In general, as temperatures warm up, stability will decrease. These decreases will be most apparent on solar aspects where the radiation is strong. The timing on this decrease will vary but can be affected by overnight freeze and aspect. Poor freezes mean avalanche danger will increase quickly with warming. Northern aspects are still holding some dry snow at upper elevations but expect a battle up and down from there. The deep persistent weak facets will be with us until the snow is gone. Be sure to asses this layer as you travel. Some good corn is out there if you can get the timing right!!

In general, as temperatures warm up, stability will decrease. These decreases will be most apparent on solar aspects where the radiation is strong. Cornices could become weak and prone to failure. The timing on this decrease will vary but can be affected by overnight freeze and aspect. Poor freezes mean avalanche danger will increase quickly with warming. Northern aspects are still holding some dry snow at upper elevations but expect a battle up and down from there. The deep persistent weak facets will be with us until the snow is gone. Be sure to asses this layer as you travel. Some good corn is out there if you can get the timing right!! Start early and be home early and avoid the heat of the day.</span></p>
