Weather Forecast
MONDAY NIGHT: Clearing skies, 30-40 km/h north wind, treeline temperatures drop to -7 C.
TUESDAY: Sunny, light northwest wind, treeline temperatures around -5 C.
WEDNESDAY: Cloudy with light flurries and up to 5 cm of new snow, 30-40 km/h southwest wind, treeline temperatures around -5 C.
THURSDAY: Mix of sun and cloud, light northwest wind, treeline temperatures around -3 C.
Avalanche Summary
Preliminary reports from Monday suggest the new snow formed some thin reactive slabs, with a few size 1.5 natural avalanches reported. Otherwise avalanche activity over the past week has been limited to small dry loose sluffs and small wet loose avalanches on sun-exposed slopes.
Snowpack Summary
Flurries over the past few days delivered 15-30 cm of snow. This snow has generally been stable, but there could still be some wind slabs at higher elevations. This snow sits above a widespread crust, with the exception of high north-facing terrain. A persistent weak layer from late January is buried 80 to 150 cm deep, but is unlikely to trigger as the last reported avalanche on this layer was in late February.
Terrain and Travel
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- Be alert to conditions that change with elevation and sun exposure.
- Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
