Regions

Glacier.

Expect to find touchy storm slab, minimize time spent in areas exposed to overhead hazard. Avalanches have the potential to run into valley bottoms.Strong winds and snowfall will persist for the day.

Weather Forecast

For all the mountain bikers and rock climbers out there, winter isn't over yet so keep your Gore-tex out! A pacific storm will deliver another 10-15cm of snow today with westerly 30-70km/hr winds. Freezing level will rise to 1700m with an alpine high of -4. Wednesday will see sun and cloud and cooler temps but the snow will return on Thursday.

Snowpack Summary

Moderate to strong southerly winds have redistributed the 20cm of new snow in the past 24hrs forming a fresh storm slab. Cool temps have kept the near surface crust below tree line intact. Watch for a buried crust on steep solar aspects and isolated patches of surface hoar, both down 30-45cm.

Avalanche Summary

A natural cycle will occur today as forecasted snow and strong winds will continue into the evening.Skier triggered sz 2 wind slab yesterday afternoon on a steep NE aspect, no involvement, read the report here. A sz 2 skier accidental occurred Saturday midday on a westerly aspect on a cross loaded feature. It ran for 350m and injured the skier.

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.
