Regions

Glacier.

A variable snowpack and potentially strong solar input today is keeping the hazard elevated. Winter avalanche conditions prevail at higher elevations, even if it feels a lot like Spring in the valley.

Weather Forecast

Expect a mix of sun and could today. Freezing levels are forecast to rise to 2000m, winds will be moderate from the SW, and we may get a trace of snow this morning. Similar weather conditions can be expected tonight and tomorrow. No significant snow is forecasted until the weekend, where we may see up to 25cm of new snow.

Snowpack Summary

Since Friday, Rogers Pass has received ~95cm of snow at treeline. The storm came in with warm temperatures and moderate to strong wind, forming storm slabs. These storm slabs remain reactive to skier triggering on specific terrain features in the Alpine and at Treeline. The March 18th layer is now buried 60-100cm depending on aspect and elevation.

Avalanche Summary

A skier accidental occurred yesterday on Teddy Bear Trees. The slab avalanche was at least a size 2.5, failing either as a storm slab, or on the March 18th persistent slab interface. Field techs will investigate further today. Another MIN report of skier accidentals and remotes in the Hermit Moraines area yesterday, click here for more details.

Confidence

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.
