Season snowfall to date
How this is estimated
Snow depth is modelled by replaying this season's weather hour by hour — snowfall, melt, sunshine and settling — then checked against government snow stations. The typical line is the same model averaged over recent seasons, so the comparison is like-for-like. Resorts report depth on packed, groomed pistes, so their figure is usually lower, especially on high, wind-exposed summits.

How this forecast works
Snow Maps blends four global weather models and works out the rain/snow line hour by hour, then calculates snowfall separately at the base (1230 m), mid-mountain (1605 m) and summit (1980 m) of Chapelco. Colder, higher terrain gets a lighter, deeper snow ratio. The range shows how far the individual models disagree: a wide range means low confidence.
