Time to start and end early to avoid the afternoon warming, increasing the overall hazard. Be aware of steep solar aspect gully features particularly in the late afternoon which could produce avalanches up to size 2.
Weather Forecast
Expect another good freeze Thurs and Friday nights. Friday daytime will be spring like temperatures but clouds and wind will increase throughout the day. Two weak cold fronts will move through Friday evening into Sunday. Daytime temperatures will be cooler and some snow which may start as rain in valley bottom. 1200m freezing level for Saturday.
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 treeline and above. Little change for sometime.
Avalanche Summary
No new avalanches were observed in the Maligne lake area today. 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.
Loose Wet
Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
