Yesterday was another somewhat un-inspiring day in the backcountry in terms of avalanche activity. To date our snowpack above 2000’ is shallow and made up of very weak snow that lacks any sort of cohesive slab. Without that slab component, we simply are not seeing avalanches in our area. At lower elevations, stout crusts that were so prevalent and annoying a week ago are decomposing, lending to improved surface conditions.
Though the skiing leaves much to be desired, it is worth a jaunt into our backcountry facet-farm simply to get eyes on what will be the foundation of our 2013/14 seasonal snowpack. There are some fun turns to be had in this recycled powder snow, just be mindful of what the ski industry refers to as “early season hazards”.
The faceting process looks to continue in the near future as temperature gradients in our shallow snowpack are well within the limits to promote facet growth.
Average snowpack depths:
Above treeline, 15-30″
Below treeline, 12-15″
The temperature inversion remained in place yesterday, though wasn’t quite as extreme as we saw at the beginning of the week. Ridge top temperatures did stay below freezing and continued a slow slide down toward what we would consider more normal December temperatures yesterday. Winds were light and variable as a high deck of clouds moved into our area from the south mid-day.
We can expect increased clouds in our region today though winds will remain light and variable. Temperatures look to be moderating throughout the day, as colder low elevation air will continue to be scoured out and replaced by a slightly warmer air mass.
Models show a slight chance of mixed precipitation tonight and into tomorrow for the Anchorage area, but given the general flow pattern and forecasted amounts its unlikely that the eastern Turnagain arm region will see much more than a few flakes.
