Extended Outlooks 1800 UTC Fri 24 Feb to 1800 UTC Mon 27 Feb Issued by the Met Office, on behalf of the Maritime and Coastguard Agency, at 222300 UTC

  1. Niton

    On Friday evening, high pressure centred in the Bay of Biscay will be ridging northeast across much of Niton. A deep low pressure system, will be centred 959 off the southwest coast of Iceland. Through Saturday morning the ridge migrates away east, however a cold front will move across the northwest of the region through the morning. A weak ridge of high pressure will then build across Niton and the UK on Sunday. However shallow low pressure systems could develop to the west of the UK, perhaps affecting the far northwest of Niton. During Monday, there is the potential for one of these features to track further southeast through Sole and Shannon. Gales are likely across Shannon, and northwest Sole Saturday. These extending east Sunday morning, into Fastnet, Irish Sea, Lundy and Plymouth before easing. Further gales are then possible across northwest Shannon overnight into Monday, before more widespread gales become possible west of 03W, perhaps occasionally severe

However an Atlantic low is also expected to develop southwest of Iceland, moving east. Various shallow low centres could also develop to the north and west of the UK. One feature is likely Sunday, developing near Rockall and moving north. During Monday there is then potential for a further feature to develop across Shannon and track northeast across Scotland. Severe gales, occasionally storm force winds, are possible across southeast Iceland and Faeroes Friday evening, with gales west of 2W. Further gales are likely across Portpatrick Saturday, and also near the system moving north Sunday. Gales are also likely Monday south of 55N, and also Fair Isle later
