Forecast Base URL
https://avcan-services-api.dev.avalanche.ca
To build a complete forecast interface, you typically need to use three endpoints together: fetch Areas to display forecast area polygons on a map, use Metadata to colour the polygons and provide alt text, then fetch detailed Products for forecast display pages.
Endpoint
GET /forecasts/{lang}/areas
Retrieves all forecast areas for the specified language as GeoJSON features.
