Dates are NOAA posting dates, which can differ from when events happened or original reports were published. Excerpts retain the source's wording and uncertainty. This account does not independently establish the cause, current outcome or safety of the area. NOAA coverage is selective; missing updates do not mean nothing happened. The map shows one approximate incident area, not a vessel track.
