Avalanche Summary

Loose wet natural avalanche activity in the afternoons continues.

Snowpack Summary

5-10cm of soft snow can still be found in the shaded alpine. Solar aspects have multiple crusts within the upper 30 cm. A total of 20-40cm of snow now sits over the March 19th crust which is present everywhere except North aspects above 1900m. The Feb 3rd crust interface is down 30-90cm. Basal depth hoar and facets make up the bottom of the snowpack. HS ranges from 560 to 150cm.

Weather Summary

Monday: Cloudy skies and flurries at higher elevations. Southwest ridgetop winds will range from 35 to 50 km/h. Precip will be mainly on the windward side of the Rockies but some snow will drift across to the eastern slopes through the afternoon. Freezing levels will be 1800-2000 m.

Terrain and Travel Advice

Be carefull around freshly wind loaded features.
Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
Avoid exposure to steep sun exposed slopes.

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 Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
