Risk of flooding in north-west midweek

Hurricane Ophelia will transition into a powerful post-tropical storm as it approaches the British Isles from the south-west on Monday. Stormy conditions are expected for Ireland, whilst gales may affect the west & north of Britain overnight into Tuesday. During midweek, a strong south-westerly wind brings a risk of further prolonged rainfall for the hills in the west & north-west.
