In the UK, the Maritime and Coastguard Agency (MCA) is responsible for the provision of Maritime Safety Information (MSI) to ships at sea, which includes the broadcast of warnings and forecasts. This includes Navigation Warnings.
The Met Office initiates warnings and prepares routine forecasts for dissemination on behalf of the MCA.
