Vessels can obtain details of all the current NAVAREA 1 warnings in force on our website www.admiralty.co.uk under Maritime Safety Information, Radio Navigation Warnings and select NAVAREA I, alternatively you can use the following link https://www.admiralty.co.uk/maritime-safety-information/radio-navigational-warnings
However it should be noted that the only approved ways of receiving Radio Navigation Warnings are from either the International SafetyNet service or the International Navtex service as laid down in SOLAS.
There is also a link under the About RNWs tab to the IHO web page with all available world wide NAVAREA warnings
This will bring up a world map with all the NAVAREAS on, by clicking on the relevant area it will take you directly to the website for the area.
For further information please contact RNW at: navwarnings@ukho.gov.uk
With regard to viewing Navtex bulletins via an ECDIS, this is not something the UKHO can advise on and we would suggest contacting the ECDIS manufacturer directly for confirmation regarding the capabilities of their product.
The UKHO do not provide NAVAREA Warnings through AVCS .
