Moderate to strong winds and a little bit of new snow over the next few days may be enough to create pockets of thin wind slab potentially by Sunday. Monitor for this condition.
Weather Forecast
Late Friday evening to Monday will bring a series of weak cold fronts. Freezing level will be 1500m Saturday then drop to valley bottom Sunday then rise again Monday. Only limited amounts of snow is expected but winds will be moderate to strong W-SW Friday evening into Monday morning.
Snowpack Summary
Suncrust is found on solar aspects. 5-10 cm of snow can be located sporadically and largely aspect dependent over a supportive temperature crust above 2200m. Weak basal facets are bridged by a strong mid-pack in most areas at treeline and above. Monitor this weekend's wind loading patterns as wind slabs may form on a slippery crust.
Avalanche Summary
No new avalanches have been observed for sometime. Debris from recent cornice falls have been noted recently on steep unskiable terrain which DID NOT propagate any avalanches on the slopes below.
Confidence
Timing, track, or intensity of incoming weather system is uncertain on Saturday
Problems
Cornices
Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
