A developing area of low pressure may produce a short spell of very strong winds. Winds will initially strengthen across some western and southwestern areas, before migrating northeastwards, clearing into the North Sea during the early hours of Sunday morning. Whilst not everywhere in the warning is expected to experience very strong winds, some inland locations may see gusts of 50-60 mph whilst gusts of 65-75 mph are possible around some coasts. The strongest winds are more likely around Bristol Channel and the west Wales coast on Saturday afternoon and early evening, then along the North Sea coast of east and northeast England overnight into early Sunday morning.

Information on update: The likelihood of impacts has been increased to reflect increasing confidence, particularly across north Wales and northern England late Saturday afternoon and evening. The warning has been removed from Scotland whilst Humberside has been added with the end time brought forward. A band of rain, heavy at times, across Wales, and northern and western England is expected to remain slow-moving during Saturday morning before making erratic eastward progress, eventually clearing early on Sunday. Whilst there is still some uncertainty in the focus for the heaviest rainfall, 20-30 mm of rain is likely to fall quite widely with some locations in the warning area seeing 60-80 mm of rain. These higher accumulations may not be confined to high ground only with these more probable over north Wales and northern England. Should confidence increase in these higher totals falling over urban or sensitive areas, this warning may be upgraded. As the area of rain clears east, a spell of strong northwesterly winds may develop later Saturday and Sunday morning, most likely towards North Sea coasts.

Information on update: The warning area has been moved southeast to remove parts of the Central Belt but to include a greater portion of England and Wales. A band of rain, heavy at times, across Wales, northern England and southern Scotland is expected to remain slow-moving during Saturday morning before making erratic eastward progress, eventually clearing early on Sunday. Whilst there is still some uncertainty in the focus for the heaviest rainfall, 20-30 mm of rain is likely to fall quite widely and there is a chance that 60-80 mm of rain could fall in places. These higher accumulations may not be confined to high ground only. Due to this uncertainty, further changes to the warning area are possible. As the area of rain clears east, a spell of strong northwesterly winds may develop later Saturday and Sunday morning, most likely towards North Sea coasts.
