The worlds' oceans have been divided into 21 areas, called MetArea's, for the provision of marine products to shipping.

The products displayed are issued by the National Meteorological Services (NMS) appointed as WWMIWS Issuing Services.
METAREA Coordinators are assigned to coordinate provision of the marine services for each area. View the MetArea Coordinator contact list.

Information on the Worldwide Navigational Warning Service (operated by the International Hydrographic Organization), may be found using the NAVAREA co-ordinators websites.

This website was developed and maintained by Meteo-France. It has been operational since June 2003 and will continue to grow and evolve. Suggestions are welcomed (Mireille Mayoka).
