Flood risk alert for parts of the UK Rain could be a blessing for England's cricket team on the final day of the third Ashes test against Australia at Old Trafford, Manchester. Photograph: Phil Noble/Reuters Weather forecasters have warned of possible floods caused by a band of heavy rain affecting large parts of the country. The Met Office issued a yellow severe weather warning, saying there was risk of flooding in south-west and northern England, Wales and southern Scotland. Up to 60mm (2.3ins) of rain are possible in the south-west of England. West Yorkshire could also be hit. Cornwall Fire and Rescue Service said there had been isolated incidents of flash flooding in the Porthleven, Perranporth, Redruth, Camborne, Bolingey, Newquay, Truro, Falmouth, Bude and Bodmin areas, which crews had responded to. Western Power Distribution said its engineers were attempting to restore electricity to more than 500 properties in the St Teath area of north Cornwall. A spokeswoman said: "We are looking into the cause and we hope to restore customers' power as soon as possible." Helen Rossington, a forecaster with MeteoGroup, said: "We have got low pressure moving across England today and a front associated with that is bringing rain to the south east of Scotland, northern England, Wales and the northern Midlands, moving eastwards during the day. Southern England could see thunderstorms moving in from south Wales this afternoon, but it looks much quieter over the next couple of days with a return to sunny spells and scattered showers. Rossington said the highest totals for rainfall registered so far on Monday were in Culdrose, Cornwall, where 11.2mm of rain fell in one hour between 8am and 9am. A Met Office spokesman said floods were a greater risk after periods of dry weather, with hardened ground not allowing water to be absorbed. Yellow warnings are the least serious severe weather alerts issued by the Met Office, ahead of orange warnings to be prepared and red warnings to take action.
