Weather: each summit’s forecast is refreshed about once a day (last update 19 hours ago). Forecast snowfall, temperature and freezing level at each summit from each area’s general-purpose model, at 10 cm of snow per 10 mm of water; the wind is the model’s wind for that spot, and real summit winds are often stronger. Prominence: how far a summit rises above the lowest col linking it to higher ground. Mountains, heights, prominence and ranges: Wikidata (CC0). Forecasts: Open-Meteo (CC BY 4.0).
