Local reports describe observed conditions. The weather forecast is shown separately; it does not establish piste quality or snow cover.
The illustration connects the three views. It is a schematic, not a route map or a picture of current snow cover.
Forecasts are model estimates at one point and adjusted elevations, not measured snow.

MET Norway ↗Schematic elevation profile
How we calculate this
Wet-bulb: Stull (2011), a near sea-level approximation. Alpine pressure effects and very cold, dry conditions limit accuracy. Potential hours use a −2°C threshold; equipment, water and operating decisions remain unknown. Snow balance uses wet-bulb precipitation partition and a configurable degree-day melt factor. Uncalibrated research model.

Open saved forecast ↗How this comparison works+
Daily comparison selects the nearest stored issue to 24 hours earlier (within 6 hours); weekly uses 7 days (within 12 hours). At least six consecutive future hours must match. Source and model version must agree. The comparison describes changes in that forecast period.
This view uses a single forecast. Probabilities and historical accuracy scores are not available.
