What we ingest
International SIGMET bulletins by FIR: hazard type (turbulence, icing, volcanic ash, tropical cyclone), severity qualifier, base and top altitudes, movement, and the raw bulletin text.
Where this feed reaches
A region on this list means we fetch it. It is not a promise of station density: a listed region can still have sparse or no reporting sites near a given airport. Where a feed does not reach a region at all, this page says so instead of showing an empty panel.
- Global — no regional boundary applies
How AeroCopilot uses it
