Cullercoats
A developing area of low pressure will transfer northeastwards from
southeast England into the southern North Sea during Friday. This low
deepens rapidly as it exits southeast England, before moving
northeastwards through the North Sea towards southern Scandinavia
during the weekend, with the deep parent low expected to later
transfer westwards towards the Shetland Islands later Sunday. There
will be a transient ridge of high pressure moving eastwards from the
Atlantic into Ireland during Saturday, ahead of an approaching
frontal system, this expected to reach western Britain later
Saturday, sliding eastsoutheastwards towards northern France during
Sunday, perhaps with a low centre developing. A westerly flow follows
across the United Kingdom on Monday. Cyclonic strong to gale in the
central North Sea becoming northwesterly to northerly in all areas as
the low moves away northeastwards, perhaps local severe gale in the
western North Sea. By Sunday evening and persisting through Monday,
mainly westerly to southwesterly gale in northern North Sea, locally
cyclonic or severe gale near Viking and Shetland, with strong to gale
westerly winds in southern North Sea and English Channel
