Regions
Glacier.
Skier/Rider triggered avalanches are possible today. Extra caution should be exercised on steep slopes where crusts are buried under the new snow and where the wind has affected the storm snow.
Weather Forecast
Today is starting off with some sun, that will make way for clouds near noon and snow falling shortly after. FL will rise to 1300m, mod winds from the SW. No significant accumulation today, but we could see 20cm by tomorrow morning. Friday night into Saturday, there will be a break in the weather before the next low moves over Rogers pass.
Snowpack Summary
30cm in the past 48hrs brings the weekly total to 60cm of storm snow. Moderate to strong winds have redistributed the new snow into wind slab on lee features. Watch for a buried crust up to 2000m on all aspects and on steep solar aspects into the alpine down 30-60cm.
Avalanche Summary
Vague report from a MIN of Puff Daddy, skier accidental? Healthy size 2, ran 200 meters in length, crown up to 1m deep in and 50m wide. A field team in the Illecillewaet area yesterday, observed limited and small activity that occurred during the storm on March 27. Artillery control on the 27th produced results up to size 3.0.
Confidence
Due to the number of 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.
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.
