Highlights

A lot of snow has been lost in the past 24 hours due to warm temperatures and rain. Above 2100 meters, we expect pockets of wind-loaded snow and wind slabs to have formed. With sunshine and warm temperatures in tomorrow's forecast, loose wet avalanches are possible.

    Above 2100 meters, a reasonable amount of snow has accumulated. Pockets of wind-loaded snow are possible on aspects lee to the previous northwest winds.

Recent Avalanche Activity

A previous loose, wet avalanche cycle has occurred with the recent rain and warm temperatures.

Current Snowpack Conditions

Warm temperatures and rain as high as 2100 meters have significantly reduced snow depth. Below 1700 meters, the snowpack is below threshold. Above 2100 meters, new snow accompanied by strong winds has loaded the higher-elevation slopes in the park.

Mountain Weather

Some cloud about the tops, otherwise fine.

Sliding Danger

Snow remains on most of the main passes and tramping routes. Sliding into rock is a potential hazard. Ice axe and crampons should be part of your winter gear.

Forecast Confidence

High

  • The snowpack structure is well understood.
