How this forecast is made
Fresh snow (hourly snowfall), freezing level and snow depth come from the Open-Meteo forecast API, which blends national and global weather models (among them ECMWF IFS, DWD ICON and NOAA GFS) and corrects them to the altitude asked for: here the summit and the base of Mammoth Mountain. Totals start from the current hour; the daily table runs in local time. Model snow depth is natural snow only. The live map shows NOAA GFS snow depth and freezing level around Mammoth Mountain.
