High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
There have been periods of rain over the past 24 hours. The pack has been soft for many days and this additional moisture will only exacerbate the problem. Loose, wet avalanches are a possibility on a full range of aspects especially, between 1000 and 2000m. If you find the pack is very soft (rotten) this morning, turn around and head for home.

Alpine level
High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
Rain over the past 24 hours has added further moisture and weight to the pack. Wet slab releases are a possibility particularly, between 1000 and 2000m. These slides could occur on any aspect and may fail to ground. Stay clear of areas where you find glide cracks or buckling.

Recent Avalanche Activity

Recent Avalanche Activity
No avalanches reported for several days. Avalanche activity is likely to increase over the next 24 hours as rainfall continues.

Current Snowpack Conditions

Current Snowpack Conditions
Rain has fallen intermittently over the past few days and the freezing level has been sitting up at between 2000 and 2300m. As a consequence, the pack is very soft and this will not change until the freezing level drops. Prior to the recent spell of cloudy Northerly weather, melt/freeze crusts were common on solar (North facing) aspects. The pack is becoming isothermic on solar aspects below 1800m. Glide cracks and areas of buckling are appearing on North facing slopes especially, on steep terrain with limited toe support.

Mountain Weather

Mountain Weather
Sunday - rain heavy at times falling as snow down to 1600m . Moderate to strong Northerly winds. The freezing level is hovering around 2000m.

Sliding Danger

Slide For Life
As Spring conditions develop, it is likely that crusts and icy areas will become common. Snow surface conditions will frequently vary greatly depending which aspect you are on - one side of a ridge maybe sun softened while the other side, will be hard and icy. Ski crampons and/or crampons and an ice axe are a well worth adding to your back country kit.
