  1. Niton

    At first large mid Atlantic anticyclone extending east across the north of the Niton region, while a small low lies 42N 20W, 1014. This low fills as it moves southeastwards Wednesday night into Thursday, allowing the high pressure to cover the entire Niton region. Thereafter high pressure will continue to dominate the weather across the Niton region, with the anticyclone moving east to become centred over sea area Biscay by midday Saturday, 1023. A large depression will follow from the west, becoming centred mid Atlantic by the end of the forecast period. Wednesday evening and overnight strong winds across eastern Thames, abating Thursday morning while strong winds develop across southeastern Fitzroy and isolated strong winds develop across northern Shannon. Friday night strong winds across northern Shannon cease, while strong winds continue across southeastern Fitzroy. Saturday strong winds become isolated across Fitzroy
