Information on update: The area of the warning has been extended to cover more of northwest Wales, including Anglesey. A deep area of low pressure is expected to bring a spell of prolonged and, at times, heavy rainfall across a large part of the UK this weekend. Across Wales and western England, rain and hill snow is expected to develop during the early hours of Saturday morning before falling as rain to all levels by late morning and continuing through to early Sunday morning. 50-75 mm of rain is expected to fall fairly widely with 100-125 mm of rain over higher ground, particularly in south Wales. There is a chance that prolonged heavy rain could become slow-moving over south Wales with up to 150 mm possible in a few places and it is here where impacts are most likely. Strong southerly winds will accompany the heavy rain and may locally exacerbate impacts.What should I do? Check if your property could be at risk of flooding.
