A coastal warning or advisory displayed for the selected marine warning area should prompt a plan review. The available guidance does not identify one named warning, severity level or threshold as the universal trigger, so singling out a particular alert in advance would be misleading. The next check is the latest service status for every intended route.
How to check the coastal warning
Select the relevant area on the coastal and sea map. The forecast for that area and its warnings will then appear on the page.
If a warning or advisory is displayed, that is the point to review the travel plan rather than relying on a remembered warning category or an earlier forecast. The guidance does not provide a fixed severity threshold that applies to every area and journey.
How to check the sailing
Check the service status for each route before travel because it contains the latest information on sailings. The marine-area forecast and the route status answer different questions: one provides the forecast and warnings for an area, while the other provides route-specific sailing information.
A displayed coastal warning should not be treated as proof that a particular sailing has changed. Any connection between the warning and an individual route must be confirmed through the current service status.
What travellers must still confirm
Before travelling, travellers still need to confirm:
- The current forecast and warnings for the selected marine warning area.
- The latest service status for every intended route.
- Whether either check has changed since the travel plan was reviewed.
The available guidance provides no fixed review deadline or automatic rule linking a particular warning to a sailing outcome. Those details cannot be inferred and must be checked against the current, route-specific information.
