Coastal Warnings are promulgated by a National Co-ordinator to ensure safe navigation within a region, out to about 250 miles from the coast. They should normally provide sufficient information for safe navigation to seaward of the fairway buoy or pilot station and should not be restricted to hazards in or near the main shipping lanes. These warnings are broadcast on NAVTEX where the region is serviced by a NAVTEX station, otherwise onSafety NET where Safety NET is being used in lieu of NAVTEX.
They may also be broadcast by other means such as VHF R/T not covered by the requirements of the GMDSS.
The messages are in English, but may also be in the local language
