Metareas

Metareas have the same boundaries as NAVAREAs, areas which are designated for the issue of navigational warnings and other related Maritime Safety Information within the GMDSS regulations.
In the context of the issue of meteorological forecasts and warnings for the High Seas the areas are referred to as Metareas. Certain Member countries of the World Meteorological Organization take on responsiblities as Preparation and/or Issuing Services for specific Metareas in the context of meteorological warnings and forecasts. In this context the United Kingdom has undertaken both responsibilities re Metarea I, the Met Office providing the warnings and forecasts and issuing them via the Inmarsat SafetyNET™ Service.

The table below is reproduced from that published in the WMO Manual on Marine Meteorological Services, WMO-No.558.
