Avalanche bulletins

5. November 2024

Safety information is always available in Skida. You can access the avalanche bulletins directly from the map, when zooming out or in the route details card. Remember to read and understand the whole bulletin, before making any decissions. And always check for the latest updates underway, we check for updated avalanche forecast from the authoroties continuously!

In your Outdoor home area, or guidebooks you subscribe to, you can access the avalanche bulletin for the starting point of the route, from within the route description. This is to make sure you check the correct bulletin for your tour. But if your tour is crossing or near other avalanche bulletin areas, it is recomended to check the nearby bulletins.

The Avalanche bulletins are provided by local authorities. We do not alter the content of the forecast. So what you get in Skida is the same information as you get in Varsom, Whiterisk, Meteo France or other equivalents.

What is provided in the avalanche bulletins?

We follow the EAWS standards for European avalanche foreacasts. The visual presentation and illustrations are based on these standards.

Avalanche danger level

It’s good information, but keep on reading. The risk level is just a number, and does not tell you where the danger is or how it affects your plans.

Avalanche danger level 1 Avalanche danger level 2 Avalanche danger level 3 Avalanche danger level 4 and Avalanche danger level 5

General avalanche warning

Avalanche bulletin providers always gives a textual description of the current avalanche risk. It is crucial to understand all aspects of the general warning, before proceeding to the rest of the bulletin. It should give you clear indications on what to expect. But keep reading, the devil is always in the details.

Avalanche problems in the avalanche bulletins

Avalanche forecasters try to predict what kind of avalanche problems that are in the different areas. These predictions are based on a set of observations. The different avalanche problems are further descibed here:

Avalanche problem gliding snow
Gliding snow
Avalanche problem new snow
New snow
Avalanche problem wet snow
Wet snow
Avalanche problem persistent weak layer
Persistent weak layers
Avalanche problem wind slab
Wind slab
Avalanche problem cornices
Cornices

Avalanche problems and their locations

In the forecast the avalanche problems are identified with an indication of where they are likely to appear, based on elevation above sealevel and direction. In Skida this is represented by a “pizza”, where each slice is representing a compass direction, North, North East, East, South East etc. Elevation is indicated on a mountain icon and with numbers representing bottom and top elevation. The colored space indicates where the problem is.

Avalanche forecast with danger level 2, indication persistent weak layers 900 meters above sealevel on North-East, East, South-East and Southern faces.

Rysstadåsen route details with slope direction and slope elevation

With the avalanche Bulletin in the example above, the route Rysstadåsen is not affected. The direction is partly covered, but max elevation of the tour is bellow the indicated problem. It would however be wise to avoid avalanche terrain at the top parts of this route for that specific date.

By presenting the avalanche problem location in the same way as we present the route direction and elevation we make it easier for you to see if the route is affected by the current avalanche problem(s).
