Radio Navigational Warnings

We act as the NAVAREA I (NE Atlantic) Co-ordinator for the International Maritime Organization (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. The provision of navigational warnings on this website is not intended to be a substitute for, or an alternative to, the International SafetyNET service or the International NAVTEX service, and does not relieve Masters/Captains of their responsibility to monitor MSI broadcasts in accordance with the provisions of SOLAS.

Many warnings are of a temporary nature, but others may remain in force for several weeks and may be superseded by Notices to Mariners.

The IHO WWNWS-SC web page allows direct access to all the NAVAREA Co-ordinators around the world who have made their NAVAREA warnings available on the web. To get to the IHO WWNWS-SC web page, click on the "Visit IHO WWNWS" button below.

To switch to a low-graphic/plain text/non-java version, click on the "Simple Text Version" button below.

The World Meteorological Organization is conducting a survey concerning the quality of messages broadcast via SafetyNet and NAVTEX to identify measures to improve service. The World-Wide Meteorological Information and Warning Service survey is available at: www.JCOMM.info/MMMS. Your participation is greatly appreciated and valued.
