The Joint WMO-IOC Technical Commission for Oceanography and Marine Meteorology

Worldwide Met-Ocean Information and Warning Service (WWMIWS)

 

The Worldwide Met-Ocean Information and Warning Service (WWMIWS) provides Maritime Safety Information (MSI) to mariners in the form of marine forecast and warning products. The WWMIWS is coordinated across the worlds’ oceans through 21 defined areas, called MetArea’s. Ships receive the MSI products via SafetyNet and Navtex communication systems, which form part of the Global Maritime Distress and Safety System (GMDSS).

The MSI products are issued by National Meteorological and Hydrographic Services (NMHS) appointed as WWMIWS Issuing Services. METAREA Coordinators are assigned to coordinate provision of the marine services for each area. View the roles and responsibilities for a MetArea Coordinator and a contact list.

The WMO/IOC Joint Technical Commission for Oceanography and Marine Meteorology (JCOMM) has an operational web site http://weather.gmdss.org·that provides a single entry point to SafetyNet and Navtex products issued under the Worldwide Met-Ocean Information and Warning Service.

The JCOMM Expert Team on Maritime Safety Services (ETMSS) is responsible for the operational coordination of the WWMIWS. View the activities of the ETMSS.
