Steps

Call GET https://api.avalanche.org/v2/public/products/map-layer for a GeoJSON FeatureCollection of all US avalanche center zones, or /map-layer/{avalanche_center_id} (e.g. SNFAC) for one center
Read each feature's properties: danger, danger_level (-1 to 5), color/stroke/font_color for rendering, and travel_advice text
Check start_date/end_date to know when the forecast was issued and expires, and warning.product for active avalanche warnings
Link users to the full forecast via the link/center_link properties rather than trying to reproduce the full narrative forecast yourself
Poll during the 6-10am Mountain Time window since centers typically publish once daily in the morning, December-April

Known gotchas

The API only exposes the 1-5 danger scale and travel advice, not the full forecast text - avalanche.org explicitly asks integrators not to alter the intent/accuracy of this limited data
Some zones show 'no rating'/grey (summary-only centers) rather than a real danger level - handle that as a distinct state, not as missing data
