Cullercoats

Wednesday evening, a broad area of low pressure is centred 995 in the Norwegian Sea. Another shallow trough is centred near Bailey and a ridge extending out of the Azores High lies Sole eastwards through the English Channel. A heat low also exists over Spain. By midday Thursday, a similar pressure pattern persists except the trough near Bailey develops into a low centred 1006 over Western Isles. By midday Friday, the ridge of high pressure declines back to the Azores, whilst another area of low pressure from the Atlantic combines with the Western Isles Low to form a broader area of low pressure centred 1001 over western Ireland. This low deepens further overnight and into Saturday, potentially reaching 995 in the Irish Sea but with some uncertainty at present. Strong winds are possible for a time across northern areas of Cullercoats during Wednesday night into Thursday morning. Near gale is possible across northwest Fair Isle during Sunday

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; Cullercoast, 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.
