On Wednesday evening, a complex low pressure area lies over the UK, with the main low over Viking, 990, and a secondary one over eastern Sole, 999. This complex low transfers eastward during Thursday, the secondary low slowly filling while transiting over south England. Meanwhile a new low pressure system deepens over the Atlantic, reaching the southern tip of Iceland by midnight, 970. It then starts dumb-belling with another Atlantic low during Friday whilst deepening further on Saturday. Details are very uncertain but its cyclonic influence is expected to extend across the whole of Britain. Strong winds expected over Fair Isle and Viking on Wednesday evening, before extending to German Bight and Fisher later. Winds generally moderating on Thursday, but with a chance of strong winds in Wight. Strong winds then spreading east across most sea areas on Friday, easing overnight. Winds strengthening again on Saturday, with near gales north of 54 North but perhaps gales in Forties and Viking
