Weather Forecast

The ridge of high pressure will continue to steer any significant weather away from the region. Today and Friday we will see increasing cloud with potentially a few flurries. Accumulations will be a few centimeters a day. Alpine highs will be -4'C with moderate ridgetop winds. Saturday will be similar but with sunny periods.

Snowpack Summary

~5cm of snow covers the previous surface of crust, facets, surface hoar and pockets of thin soft slab. Northerly winds have created pockets of soft slab in the immediate lees of ridges. Overall the snowpack is now well settled and strong.

Avalanche Summary

Small pockets of windslab have been reactive to skiers at ridgetop and the loose surface snow sluffs on steep slopes. No new natural avalanches have been observed recently.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
