<p>Poor Snowpack structure confined to Storm Snow and Storm Slab issues. Touchy and Widespread. </p>

Snowpack

Instability Comment
<p>See above for Storm Slab issues, and multiple reports of Catch and Carry validate Widespread sensitivity. With the warm to moderate temperatures on Friday, these issues should be less Reactive on Saturday.</p> <p>Contributing Factor of Wind Loading on Friday appeared to exacerbate the Storm Slab Problem. Lingering Wind Slabs on Saturday may still be an issue. </p> <p> </p> <p>Clear skies and rising temperatures on Saturday may likely help activate any isolated and the few remaining lingering Storm Slab weaknesses, but these should be settled out signifcantly compared to Friday Cycle. The big issue will likely be Wet Loose activity. Supportable bed surfaces on the Solar aspects will help in potentially producing long running sun induced natural avalanches. </p>

Elevation dependent storm totals with HST at 8000' reaching 45cm and Upper BCC easily hitting at least 60cm. 

 

Attempted tour to Back Bowls, and pulled the plug after 100 feet of entering BC, at 0930 HST at least 50cm of upside-down/inverted snow, with 20 cm of four finger plus to one finger slab resting on top of fist plus storm snow, very easy hand shears with cracking; Second option: Lodge shot with 28 cm of rightside-up Storm Snow with no slab, Very slight bottom feeding on a Turning Surface that was a 5 cm spongy/friable m/f crust with four finger minus cold dry snow below, skied well without issues.
