Check out that forecast to get a feel for the more complex snowpack and the associated Persistent Slab Problem. In the north it appears that two buried weak layers may be problematic: The mid November surface hoar/facet/crust combo down 70 - 90 cm and the weak sugary snow (large facets) near the ground. Little is known about the particulars of this setup, more observations would be great!</span></p><p class="p_CC664AAA"><span class="s_17AE1194">In the southern portion of the region observations indicate that the snowpack is much more homogeneous and strong. There have been no reports of deeply buried weak layers. The Black Friday storm came in wet and finished cold. As a result, the structure consists of 15 - 25 cm of cold snow on top of a 2 - 6 cm supportive pencil/knife hard crust which was been observed as high as 2100. This crust could act as a bed surface in the future, but for now it appears to be bridging any deeper weaknesses.</span></p>
