    A spell of persistent rain, heavy at times, accompanied by windy conditions, is expected to affect parts of southern and southwestern England and parts of south Wales from the early hours of Saturday onwards into Saturday late afternoon or evening.

    20-30 mm of rain is expected quite widely across the warning area with 50-70 mm on south-facing slopes. Higher ground in southern parts of Devon and Somerset are likely to see the highest totals with locally in excess of 80 mm possible over parts of Dartmoor. In addition, southerly gales or severe gales are expected with gusts of 40-50 mph inland and locally 65 mph over higher ground and south-facing coasts.As this rain will be falling on near-saturated ground, please be aware of the risk of localised flooding and perhaps some disruption to travel.

    An area of very strong winds is likely across parts of southwest and southern England, in particular the coasts of Cornwall, as well as south Wales on Monday morning before winds gradually ease during the afternoon and evening.

    Gusts of 60-70 mph are possible, particularly in association with heavy showers running across the area, with 80 mph gusts possible in exposed coastal districts. Some very large waves are also likely along the north coast of Cornwall in particular.Please be aware of the potential for disruption to travel as well as localised damage to structures and interruption of power supplies.

    This is an update to the alert issued on Friday to broaden the area affected by the strong winds into south Wales, the Bristol Channel and further along the south coast. This also moves into the medium impact column.
