Confidence

Poor - Due to the number of field observations

Weather Forecast

Light snowfall is expected on Saturday, tapering to flurries on Sunday/Monday. Winds are expected to be light to moderate from the south-west to south-east.

Avalanche Summary

There are no new avalanche reports from the region. Please let us know what you're seeing out there. Submit your information under the 'Avalanche Information' tab at the top of the page.

Snowpack Summary

Around 20cm of recent snow sits on previously rain-soaked snow below treeline. At alpine elevations, recent storm slabs and wind slabs may still be sensitive to triggers like the weight of  a person. Deeper in the snowpack, weaknesses such as loose sugary facets and crusts exist at least in some locations. We have limited 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.
