Navigation Warnings on the Web:

The following map shows the limits of the 21 Operational NAVAREAs.
Clicking on a NAVAREA title will take you to the NAVAREA Co-ordinators' website where Navigational Warnings are listed. (Note not all NAVAREA Co-ordinators publish warnings on the World Wide Web, some only provide Notice to Mariners.)

NB    The availability of Navigational Warnings on the web does not relieve Masters / Captains of the requirement to receive Navigational Warnings via IMO/IHO approved broadcast systems, as websites are not continuously updated and not necessarily monitored for correctness.
