Regions

Glacier.

Expect travel conditions below 2200m to be rugged in the refrozen snowpack.  Watch for storm slab and avalanche hazard as you move into the alpine.

Weather Forecast

Flurries will bring 2cm today accompanied by gusty north winds. High pressure will bring cold clear conditions for Sunday. Monday the next storm system comes bringing periods of snow.

Snowpack Summary

The midweek warm, wet, storm brought heavy rainfall as high as 2400m. Upper elevations received over 50cm of storm snow accompanied by extreme west winds that raked the alpine. The storm ended with a rapid cooling trend refreezing rain soaked snow. The cooling trend was accompanied by light snowfall partially softening the crusted surface.

Avalanche Summary

A significant loose wet avalanche cycle occurred with the last storm with slides up to size 3 along the highway corridor. No new avalanches observed in the last 24hrs.

Confidence

Due to the number and quality of field observations

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.
