Avalanche Forecast

Poor - Freezing levels are uncertain

Friday: Clouds and a few cm of snow, falling as rain below treeline. Freezing level around 1200 m. Light northerly winds.Saturday: Mainly cloudy, with sunny breaks. Some lingering light precipitation is possible in the morning, becoming dry by afternoon . Light, variable winds. Freezing level around 1200 m.Sunday: Mainly cloudy. Freezing level near 1500 m. Light winds, increasing from the SW by evening as a low pressure system approaches.

Several natural glide avalanches were reported this week on E to SW aspects below treeline, in the size 2-3.5 range. Wet loose avalanches up to size 2.5 were also observed in response to warming and sunshine. Last week, a large icefall triggered a slab in the Bear Pass area, creating a size 4 avalanche.

Glide cracks have opened up and pose the threat of large, full-depth releases, especially on steep rocky terrain features at low elevations. Otherwise, a relatively strong and deep spring snowpack exists, which becomes weak during periods of warm weather or rainfall. Recently, a lack of overnight freezing below about 1500m has left the snowpack weak. Large cornices and ice cliffs pose a threat from above. Pockets of dry snow and surface hoar may still be found on high north aspects. Areas of wind slab may exist near ridge crests.
