ACCUM merges live snow conditions with avalanche forecasts into a single GO / CAUTION / NO-GO / SKIP verdict. A verdict is a suggestion computed from data, and data can be wrong, stale, or misread. Always verify with your local avalanche center and use proper training, gear, and judgment in the backcountry. The decision is yours, made in the field.
Weather and snow data by Open-Meteo (CC-BY 4.0 ). Avalanche danger ratings are published by their issuing forecast centers — the US Forest Service National Avalanche Center and the American Avalanche Association, Avalanche Canada, and European avalanche warning services. Each resort credits its own center; always read that center's full forecast before travelling in avalanche terrain.
