    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.
