Evaluate snow and terrain carefully before committing to big lines. Watch for unstable snow on isolated features.
Weather Forecast
Sunday will be flurries, seasonal temperatures, and potentially strong alpine SW winds with light to moderate speeds at lower elevations. Monday may bring up to 10cm of snow and diminished winds locally to the Icefields. Precipitation amounts are uncertain and low confidence for Monday. Tuesday will be sunny, cooler temperatures, and light winds.
Snowpack Summary
Variable windslabs exist at ridgetop and exposed alpine and treeline locations. A solid midpack bridges weak basal depth hoar. Un-supportive facets dominate lower elevations. Surface conditions range from dust on crust, to sustrugi, to hard slab, with the odd pocket of sheltered soft snow offering a few turns, ending with wallowing below treeline.
Avalanche Summary
No new activity was noted on Saturday's patrol. Its been a while since significant avalanche activity has been observed. Don't let your guard down as allot of variability exists across the landscape.
Confidence
The weather pattern is stable on Sunday
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.
