The extended outlook information

The extended outlooks are issued once a day, at 2300 GMT and cover the next 3 to 5 days.

For the extended outlooks the waters surrounding the British Isles are divided into three areas: Cullercoats, Portpatrick and Niton. These three areas reflect the coverage areas of the UK's Navtex transmitters, which overlap in some areas.

The extended outlook forecast contains details of the likelihood of gales or storms, a general synopsis and a general forecast for the area of coverage of each Navtex transmitter.
