By midday Saturday an area of low pressure will be centred west of Fitzroy, 1002. This low will drift northwards and deepen slowly before moving eastwards across the UK as a complex feature on Sunday. During Monday the Azores high will re- establish itself across Niton. Near gale force south or southeast winds look set to develop across northwest Fitzroy and west Sole during Friday night, extending to Shannon by Saturday morning. These will persist through Saturday veering Westerly in northwest Fitzroy but remaining strong. During Sunday winds will ease through these sea areas with no further hazardous winds forecast in Niton. While light winds may lead to localised reductions in visibility widespread fog is not expected.
