Buried surface hoar reactive to rider triggering with larger propagation, chose your terrain carefully.
Weather Forecast
Low pressure system over the region today is forecast to bring light to moderate amounts. Snow tapering off by Tuesday morning with sunny breaks by the afternoon. The next system will arrive Tuesday night with light precipitation into Wednesday.
Snowpack Summary
50cm of new snow in the past 4 days. Slab over Feb 12 surface hoar/crust layer 40-55cm thick, fist to 1 finger snow. Well settled mid pack with no significant layers below Feb 12 surface hoar.
Avalanche Summary
Yesterday: A skier remote triggered size 2.0 slab avalanche from 30m away. 2010m, North aspect, 35-40degrees, 42cm deep, 100m wide X 100m long on the Feb 12 SH sz 3-8.3 avalanches in the highway corridor size 1.5 to 2.0.
Confidence
Intensity of incoming weather systems is uncertain on Monday
Problems
Persistent Slabs
Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
Loose Dry
Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
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.
