In-flight hazard advisories - SIGMET / AIRMET / G-AIRMET (NOAA AWC)

Active in-flight hazard advisories from the NOAA/NWS Aviation Weather Center: international SIGMET (worldwide), US convective SIGMET/AIRMET, and US G-AIRMET, unified into one list with a GeoJSON area and a centroid for bounding-box filtering. Filter by advisory type, hazard and bounding box. Consultative only; not a substitute for an official preflight briefing.
