Volcanic ash advisories (Washington VAAC)

Current volcanic ash advisories from the NOAA/NESDIS Washington VAAC. Each advisory carries the volcano summit, an observed ash-cloud polygon plus up to three forecast polygons (+6/+12/+18 h) with flight-level bands (in metrics.ash_clouds). Severity is Sugra-computed from the aviation colour code / ash presence. Filter by bounding box (on the volcano summit). Sugra retransmits; it is not an official flight-decision source.
