Continuously assess for changing conditions as you move through terrain. Winter like conditions could still be found at higher elevations.
Summary
Confidence
Low - Uncertainty is due to the limited number of field observations.
Weather Forecast
Monday night: Up to 5 cm of new snow expected with light to moderate southwest winds. Freezing level falling to 1100 m.
Tuesday: A mix of sun and cloud with flurries bringing up to 5 cm of new snow for most of the region, eastern slopes could receive 10 to 15 cm. Light variable winds and freezing levels around 1700 m.
Wednesday: A mix of sun and cloud with up to 5 cm of new snow possible. Moderate northwest to west winds and freezing levels around 1700 m.
Thursday: A mix of sun and cloud with the possibility of flurries bringing trace amounts of new snow. Light to moderate west winds. Freezing level around 1800 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 rider triggerable wind slab could still be found in the alpine. When the freezing level rises or the sun comes out wet loose avalanches become likely.
Snowpack Summary
Dry snow and pockets of wind slab can still be found in the alpine. The upper snowpack contains several crusts that extend to mountain top on solar aspects. Moist snow will likely be observed at lower elevation terrain and on solar aspects if the sun comes out.
The snowpack below treeline is thinning quickly.
Cornices are 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.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
- Minimize your exposure time below cornices.
Problems
Wind Slabs
Winter conditions will likely persist at higher elevations for the next few days. Winds slabs are possible. Keep an eye on new snowfall amounts and look for wind transport as you gain elevation.
Aspects: All aspects.
Elevations: Alpine.
Likelihood
Expected Size
Loose Wet
When the freezing level rises or the sun comes out wet loose avalanches will become likely. Back off slopes as the surface gets moist and avoid steep slopes above terrain traps where getting caught in even a small avalanche could be consequential.
Aspects: All aspects.
Elevations: Alpine, Treeline.
