Extended Outlook

2100 UTC Friday 29 July to 2100 UTC Monday 1 August 2016
Issued by the Met Office, on behalf of the Maritime and Coastguard Agency, at 272047 UTC

Cullercoats

Friday evening, a broad low is situated across the Norwegian Sea, Scandinavia, and most of Cullercoats, with central pressure 1002 Norway. High pressure lies out southwest of Portpatrick and Niton, with a ridge extending across central Europe. The pattern remains similar overnight and into Saturday, with low pressure remaining to the northeast of the UK and high pressure to the southwest. By Sunday, remaining similar again, although with the low centre sinking south into Viking 999. At this time, high pressure starts to move eastwards across parts of southern Portpatrick and across much of Niton. Much of Monday remains similar, but later low pressure systems are likely to arrive from the Atlantic across parts of Niton and Portpatrick, with some uncertainty on timing at this stage. Whilst this happens, the broad low pressure remains slow-moving across Scandinavia with high pressure over western Europe. Strong winds are likely across northern parts of Cullercoats during Sunday and Monday, but no gales

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.
