The general snowpack structure consists of a weak base with a slightly stronger (but still weak) upper layer of snow that fell last Thursday, Nov 21st. The most concern can be found in areas that have been wind loaded in the last couple days, with a stiff and cohesive wind slab. There is still some evidence visible from natural avalanche activity caused by the wind. All avalanche activity that we have seen in the last 2 days has followed this pattern.
Leeward facing slopes, which are predominately southeast and east faces but may include other aspects, are the primary concern today. The thin and shallow snowpack makes all avalanche activity low volume, but exposed rocks and trees create an additional hazard that we don’t experience most of the winter.
Clear and cold weather persists across the region. Temperatures this morning hover around zero F. A few weather stations are reading higher, and a few are reading lower. Wind at the ridgetops is expected to remain 15-30mph from the North.
This pattern is expected to to stay with us through the weekend. A warming trend is forecasted to start on Sunday with precipitation (hopefully) by Tuesday.
