Regions

Glacier.

Some sneaky storm slabs are still reactive to skier triggering in isolated locations- assess convex rolls carefully.

Expect some bumpy, refrozen snow for travel in the morning on solar slopes and all aspects below treeline!

Weather Forecast

We are into a cooling/drying trend after our warm wet weather from earlier this week, with high pressure building over Rogers Pass.

Tonight: Cloudy with clear periods. Low -11*C. Moderate N wind.

Sun: Mix of sun and cloud. Low -11*C, High -8*C. Light W wind.

Mon: Flurries, trace accumulations. High -8*C. Light W wind with moderate gusts.

Snowpack Summary

Fluctuating temps have settled the upper snowpack & created a surface crust below 1500m (higher on solars).

Up to 45cm of snowfall early in the week with warm temps and a brief wind spike, created storm slabs over the Feb 26th interface - wind effect in open areas, small surface hoar and facets in sheltered terrain, and sun crust on steep solars.

Avalanche Summary

A possible skier accidental size 1.5 slab avalanche occurred in the top of the Teddy Bear trees area today.

Several size 1-1.5 loose snow avalanches have been triggered by the sun on steep slopes at all elevations over the past few days.

Confidence

The weather pattern is stable

Problems

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.

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.
