Extended Outlooks 1800 UTC Wed 27 Jul to 1800 UTC Sat 30 Jul Issued by the Met Office, on behalf of the Maritime and Coastguard Agency, at 252300 UTC

  1. Niton

    On Wednesday evening a ridge of high pressure lies across the whole of Niton, this, combined with the seasonal heat low over Iberia is responsible for near gale strength northerly winds in southern Fitzroy. Overnight Wednesday and during Thursday a shallow low in the northeast Atlantic moves east into Rockall, becoming centred 1004 Irish Sea by Thursday evening, bringing strong winds to Shannon, Fastnet and Lundy. The ridge of high pressure across the rest of Niton declines slightly, but strong winds persist in Fitzroy, especially further southeast where gales are possible near the Galician coast. Overnight Thursday the low in Irish Sea continues to move east and crosses the UK into the North Sea by Friday morning, with strong winds easing in Shannon, Fastnet and Lundy, with weak high pressure building again over Niton, and strong winds persisting in southern Fitzroy. No hazardous winds are forecast across Niton on Saturday
