What the reports establish
These reports were linked by category and sea, with positions within 30 nautical miles and issue dates within 30 days of another report's recorded in-force span. Links can extend through other members, so the full group can cover a larger area or period. Proximity does not confirm that they describe one incident.

Report comparison · 2 notices
Each report is compared with an earlier notice it explicitly cancels, when available, or with the preceding report. Changes refer to recorded wording and parsed fields; quoted lines are textual differences, not a verified account of how an incident developed. Nearby reports can describe different hazards. A status explanation is given once, on the first notice with that status.
