This is an English summary of the current avalanche forecast. It contains information about the avalanche danger rating, a description of the current avalanche problems combined with recommendations for terrain travel and risk management.
Evaluate snow and terrain carefully; identify features of concern and manage risk accordingly.

Risk management
Avalanche conditions are especially dangerous or difficult to predict and anticipate. Manage the risk by making conservative terrain choices avoiding steep slopes.
Characteristics
- Slabs resting on top of persistent weak layers can produce large avalanches.
- They stabilize slowly, tending to persist for several weeks or longer and often have dormant periods, becoming active again when the weather changes.
- Persistent slabs can often be triggered by light loads and tend to release above the trigger making it difficult to escape.
- Avalanches are often triggered remotely from a long distance away and slabs often propagate wide in surprising and unpredictable ways.
- There are often no visible signs of persistent slab instability. Lack of avalanche activity and lack of danger signs are NOT reliable indicators of stability.
Can avalanches be triggered? In how many places?
Although the avalanche problem might not obvious you could trigger avalanches on a few steep slopes. Heavier loads like groups of people, machines or cornice falls increase likelihood of triggering.
How large and destructive can avalanches become?
Avalanches can get large enough to bury a car and have the force to break trees or destroy a small building (size 3). When people are caught by avalanches of this size, the probability for severe consequences is very high.

Wet avalanches
Wet slab and loose wet avalanches. Wet Slab avalanches are the release of a cohesive layer of snow (a slab) that is generally moist or wet when the flow of liquid water weakens the bond between the slab and the surface below (snow or ground). They often occur during prolonged warming events and/or rain-on-snow events. Wet Slabs can be very unpredictable and destructive. Wet Loose avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers. Aviod steep terrain when and where the snow is moist.
Can avalanches be triggered? In how many places?
Sensitive even at low load on individual slopes
How large and destructive can avalanches become?
Avalanches will most likely be small and in most cases relatively harmless, though could knock you off balance and can be dangerous near all kinds of terrain traps (size 1).
