Extended outlook forecast

Issued: 2025 on Thu 02 Jul 2015 UTC

Issued by the Met Office, on behalf of the Maritime and Coastguard Agency

Valid from 2100 on Sat 04 Jul 2015 UTC until 2100 on Tue 07 Jul 2015 UTC

Cullercoats

At the start of the period on Saturday evening a large area of low pressure will be located west of Ireland. At the same time pressure patterns across continental Europe will be slack. The general pattern will change very little through the forecast period with the low west of Ireland moving very little, although at times smaller centres will rotate around it and merge into the system. Meanwhile over the continent there will if anything be a small build of pressure by the end of the period. For Cullercoats there is no signal for strong winds across most of the area throughout. The exception could be Fair Isle right at the start of the period. The light winds could lead to the formation of some sea fog at times, this perhaps most likely over the southern North Sea during Sunday and Monday.

Niton

At the start of the period on Saturday evening a large area of low pressure will be located west of Ireland. At the same time pressure patterns across continental Europe will be slack. The general pattern will change very little through the forecast period with the low west of Ireland moving very little, although at times smaller centres will rotate around it and merge into the system. Meanwhile over the continent there will if anything be a small build of pressure by the end of the period. With this set up the strongest winds will always be across the north west of Niton, with parts of Fitzroy, Sole and Shannon likely to see strong winds throughout. Winds across Shannon in particular could approach Gale force at times, especially from Sunday onwards. Elsewhere there is no signal for strong winds at any time this period.

Portpatrick

At the start of the period on Saturday evening a large area of low pressure will be located west of Ireland. At the same time pressure patterns across continental Europe will be slack. The general pattern will change very little through the forecast period with the low west of Ireland moving very little, although at times smaller centres will rotate around it and merge into the system. Meanwhile over the continent there will if anything be a small build of pressure by the end of the period. With this set up persisting throughout the period strong winds will affect large parts of Portpatrick for most of the time. The strongest winds are likely on Tuesday when gales are possible in Bailey, Faeroes and South East Iceland sea areas. Shannon could see gales too, but the risk here is not as high.

Extended outlook overview

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

For the extend 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.

In the UK, the Maritime & 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. The Met Office initiates warnings and prepares routine forecasts for dissemination on behalf of the MCA.
