Summary
Confidence
Moderate - The snowpack structure is generally well understood.
Weather Forecast
Sunday night: up to 5 cm of new snow expected at higher elevations. Moderate to strong south winds and freezing level falling to 1500 m.
Monday: 5 to 10 cm of new snow expected at higher elevations with moderate southerly winds. Freezing level rising to 2100 m.
Tuesday: A mix of sun and cloud with the possibility of flurries bringing up to 5 cm of new snow at higher elevations. Light variable winds and freezing levels around 2000 m.
Wednesday: Stormy with 5 to 15 cm of new snow expected at higher elevations. Moderate northwest winds and freezing levels around 1700 m.
Avalanche Summary
Natural wet loose avalanches up to size two have been observed throughout the region over the past few days. Information is limited at this time of year. Please consider submitting to the Mountain Information Network!
We suspect that that new wind slabs could form in exposed terrain on Monday. As the freezing level rises small wet loose avalanches are possible.
Snowpack Summary
New wind slab will likely form on northerly aspects The upper snowpack contains several crusts that extend to mountain top on solar aspects. Moist snow will likely be observed at lower elevation terrain.
The snowpack below treeline is thinning quickly.
Cornices are very large and exposure to slopes beneath them should be minimized, especially if the weather is sunny, warm, or windy.Â
Terrain and Travel
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Minimize your exposure time below cornices.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
Problems
