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.
The Met Office said in a yellow weather warning:
.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..
The warning is in place until 3 am on Sunday 21 September.
