Alpine level
High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
Loose,wet avalanche activity is a possibility particularly, on solar (North facing) aspects during the middle of the day.The key to finding good (and safe) Spring corn skiing and riding is timing. Ideally, you want to arrive at the top of a slope as the surface is releasing but before, it becomes too soft. If the snow under your skis or board is becoming very soft or slushy, it is time to move to a cooler area. You may need to change aspect several times to enjoy optimal conditions.

Recent Avalanche Activity

Recent Avalanche Activity
No avalanches reported for a number of weeks. Avalanche activity is likely to increase over the next couple of days with fresh snow at upper elevations.

Current Snowpack Conditions

Current Snowpack Conditions
A significant amount of new snow may fall above about 1800m over the next 24 hours. This new snow will land on crusts in many places and as a result, the bond to the old surface will be suspect. The mid and lower pack are generally well consolidated. Melt/freeze crusts have been widespread particularly, on solar (North facing) aspects.

Mountain Weather

Mountain Weather
Saturday - rain, falling as snow down to about 1800m. Moderate Northerly winds.

Sliding Danger

Slide For Life
Areas of hard re frozen snow and crusts are common at this time of year. Adding ski crampons and/or crampons and an ice axe to the equipment in your touring pack is a good idea. It is important to keep in mind that one side of a ridge (North facing) may be sun softened while the shady side (South facing) is still hard and icy.
