Cullercoats

Throughout much of this period an area of high pressure is expected to be centred over or near the east of the North Sea, extending a ridge across the UK, whilst low pressure resides over Spain. On Wednesday night into Thursday, a low pressure system to the northeast of Iceland is expected to move east across the north Norwegian basin into northern Scandinavia. On Friday night and through Saturday, the high cell is forecast to weaken slightly and move east into the Baltic, as a small low pressure system in the Atlantic moves slowly east, to lie west of Fitzroy at midday on Saturday. On Wednesday evening, strong to near gale force winds are expected across the far north of Cullercoats. Winds easing overnight, and generally no further hazardous winds are forecast for Cullercoats during this period. However, strong winds may affect the Dover Strait and in the English Channel at times
