Current Snowpack Conditions

Warmer temperatures have resulted in a well-settled snowpack, and the last storm snow will have settled and bonded well. Recent wind slab danger above 2000m will have been resolved by Friday and Saturday's high freezing level. The snow on sunny aspects may be sensitive to sun and warm temperatures.

Mountain Weather

Fine. Freezing level rising from 600m to 1300m by the afternoon.

Sliding Danger

The snow will be hard in places. Ice axe and crampons will need to be carried for mountain travel.

Forecast Confidence

High

  • We are confident due to a stable weather pattern.
  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.
