Extended Outlooks 1800 UTC Fri 18 Apr to 1800 UTC Mon 21 Apr Issued by the Met Office, on behalf on the Maritime and Coastguard Agency, at 162300 UTC

  1. Niton

    On Friday evening an area of high pressure extends from the mid Atlantic across the UK to Scandinavia. A slow moving, slack area of low pressure lies across much of southern Europe, across Biscay, Fitzroy and Trafalgar. High pressure will drift gradually northwards over the weekend and a low centre, 999, is expected to develop over the Low Countries on Saturday night. This is expected to move westwards across southern parts of the British Isles through Sunday to lie to the south of Ireland by late on Monday. For the Niton area this set up means there will be little in the way of strong winds through most of the forecast period. There is a risk of strong winds in Lundy, Fastnet and Irish Sea late on Sunday as the low pressure centre moves from the east, with these easing by Monday morning
