The Met Office has issued a Yellow Warning of Rain.
Issued at: 1036 on Fri 12 Jun 2015
Valid from: 1100 on Fri 12 Jun 2015
Valid to: 0900 on Sat 13 Jun 2015
Persistent rain, locally very heavy, will spread across southwest England and south Wales today, whilst isolated severe thunderstorms may well develop further east bringing the risk of torrential downpours. Rain and showers will spread north through Friday night into Saturday morning, easing with time.
Whilst most places will miss the heavier rain, the public should be aware that there is a chance of some very localised significant disruption, mainly from surface water flooding. Lightning and hail could also cause some impacts.
Chief Forecasters analysis:
An area of warm, humid, unstable air will move north across the region today and tonight. Thunderstorms bring the potential for 20 to 30 mm falling within an hour or so, probably on a very localised basis and more likely roughly Dorset and Somerset eastwards to Home Counties. More persistent rain will give 10-20 mm quite widely over southwest England and south Wales with the risk of more than 40 mm locally.
