Cullercoats
Late Sunday a low, pressure near 990, is expected to lie centred over the Faeroe Islands. At the same time, a large but weak area of high pressure is expected to cover much of continental Europe. The aforementioned low, initially slow moving, is expected to move northeastwards through Monday, reaching the Norwegian Sea, deepening 988, as a ridge of high pressure builds east across Europe from the Azores high. Then a couple of small, weak lows on frontal waves may develop on frontal systems, moving east across the UK during Monday and Tuesday. Wednesday the parent low, associated with the frontal waves, will start to move southeastwards from the south of Iceland, towards Scotland. Occasional strong winds or near gales are likely at times north of 58N through Monday, especially across Shetland, easing overnight. Thereafter no strong winds are forecast across the Cullercoats region
Niton
A large but weak area of high pressure is expected to cover much of continental Europe Sunday night, with the main Azores high located well to the southwest of the UK. Monday a ridge of high pressure builds east across Europe from the Azores high. Then a couple of small, weak lows on frontal waves may develop on frontal systems, moving east across the UK during Monday and Tuesday. Wednesday the parent low, associated with the frontal waves, will start to move southeastwards from the south of Iceland, towards Scotland, resulting in the decline of the ridge of high pressure to the south. Overall no hazardous winds are expected across the Niton region throughout the forecast period. However, there is a chance of occasional strong winds developing Wednesday across the far south of Fitzroy, but more especially strong to near gale force winds may develop across Shannon through Wednesday afternoon. However, confidence is low regarding this
