Avalanche Danger Ratings by Forecast Zone for a US Avalanche Center (Avalanche.org)

avalancheorg/danger-map-by-center

The current avalanche danger rating, travel advice and forecast link for every forecast zone of one United States avalanche center, such as NWAC (Northwest), CAIC (Colorado), UAC (Utah) or GNFAC (Gallatin). Returns the provider's GeoJSON feature collection with one feature per zone: danger label, numeric danger level (-1 when the center is out of season and gives no rating), colour, the issuing center and a link to its full forecast, plus the zone polygon. The feature id is the zone id that Avalanche Forecast takes. An unknown center id returns a collection whose features are null. This is safety information relayed from the issuing center (center and center_link name it), never a forecast of record: read the issuing center's full forecast before travelling in avalanche terrain and do not rely on this copy alone. Data from Avalanche.org / the American Avalanche Association and the issuing avalanche center, served by Eden Engine; not an official Avalanche.org product.

Data source

Avalanche.org (American Avalanche Association)
