It is desirable that a vessel encountering hurricane or typhoon conditions sends weather reports to the closest meteorological service at which time interval?
• SOLAS V – Safety of Navigation requirements on weather reporting • Obligations of ships during tropical cyclone (hurricane/typhoon) encounters • Typical international synoptic observation intervals used by meteorological services
• Think about how often meteorological services normally receive routine ship weather observations and how this might change (or not) in severe weather • Consider what is practical and sustainable for a ship in heavy weather over many hours, not just for a short emergency period • Ask yourself which interval best balances timely updates for forecasters with the workload and safety of the crew during a storm
• Check what interval is commonly associated with standard marine weather observations on the high seas (look for 3‑hourly vs 6‑hourly cycles) • Verify in SOLAS or meteorological guidance whether special reports in cyclones follow the same pattern as routine reports or are more frequent • Make sure the option you pick would still be realistic for a vessel dealing with heavy seas, reduced mobility, and crew fatigue
