Radio Navigational Warnings (RNWs)


We act as the NAVAREA I (NE Atlantic) Co-ordinator for the International Maritime Organisation (IMO) and International Hydrographic Organization (IHO) Worldwide Navigational Warning Service (WWNWS) and also as the United Kingdom National Co-ordinator for issuing coastal navigational warnings.

Whilst the UKHO will attempt to keep this site up-to-date by adding and cancelling navigational warnings in real time, for reasons beyond its control, this may not always be possible.

The approved method of receiving Maritime Safety Information (MSI) is via the appropriate IMO, Global Maritime Distress and Safety System (GMDSS) broadcast systems as defined by the WWNWS. For more information please see the 'About RNWs' tab below.
