Regions

Glacier.

Watch for changing conditions in the new snow, wind and temperature changes will promote slab formation

Weather Forecast

5-10cm throughout the day today with precipitation intensity increasing this afternoon. Winds light W and a high of -8 at treeline. Snow tapering off overnight as a weak high sets up tomorrow and Monday with winds continuing light W, temperatures falling and flurries.

Snowpack Summary

45cm of storm snow in 48hrs with light to mod S-W winds. Variable layers of resistance and sun crusts isolated to steep SW aspects reported within the storm snow over a strong snowpack of mostly rounds.

Avalanche Summary

Numerous natural avalanches to size 2.5 from all aspects yesterday with dust from them running far.

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.
