More snow, wind and rising freezing levels will keep the hazard elevated. Use caution approaching wind effected terrain and avoid cornices overhead
Weather Forecast
Today should be a break between storms that have been bringing precip to Rogers Pass. The good news is more snow by the weekend but the bad news is that the freezing level is going to be steadily rising after each pulse of moisture. Skies will be cloudy today with flurries. Frz lvl will be at 1500m, alpine highs of -4 deg & SW ridge winds 25-35kph
Snowpack Summary
15cm of new snow with mod winds have created soft slab burying old the previous windslab in alpine. This brings our storm snow to 40cm on the Feb 27 layer which is a variable crust on SE-W asps & widespread surface hoar/stellars on shaded aspects. On a S asp field crews experienced whumfs from this layer on Monday.
Avalanche Summary
Yesterday natural avalanche activity tapered off with minimal precip and little solar input. The windslab in the alpine remains touchy and was triggered yesterday by a group on Puff Daddy 30cm deep and 30m wide running 10m to a natural bench.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
