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.

Current notices and reporting context in the North Pacific Ocean →What the numbers show
All 2 located notices give the same position (to about half a mile).
Together the notices were in force for 2.7 days over an issue span of 3.5 days; overlapping notices are counted once.
Reading these warnings
- Position (degrees and minutes)
- How warnings write positions: degrees, a hyphen, then minutes, with N/S and E/W — 49-40.8N 003-43.8W.
- Date-time group (DTG)
- A compact UTC timestamp — day, hour and minute followed by Z — such as 201500Z for the 20th at 15:00 UTC.
- Cancellation reference
- A line that cancels an earlier warning by its number, such as CANCEL HYDROLANT 1085/12.
- NAVAREA
- One of the 21 ocean areas of the World-Wide Navigational Warning Service, each with a coordinator that broadcasts long-range warnings.
- CANCEL THIS MSG
- The warning's own expiry: a line telling the reader when the message cancels itself.
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.
