Thoughts and prayers are with all affected. Looks as though the worse is yet to come. Forecasters have extended flood warnings across the UK ahead of torrential rain and gale force winds expected over the next 24 hours. The Met Office said the heaviest downpours would arrive on Monday morning as a storm band sweeps over England and Wales, accompanied by strong to gale force winds. The news does not bode well for tennis fans keenly awaiting the first day of Wimbledon, where stars such as Tim Henman, Andy Roddick, Roger Federer and Justine Henin are expected. And with no roof on centre court this year, play is likely to be stop-start for most of the day. The entire month's average rainfall - more than two inches - is predicted from Yorkshire to north east Wales, with up to four inches in some areas. The exceptional amount of rain is likely to cause more widespread disruption and flooding than in recent days, especially in areas that are already saturated, the Met Office warned. The downpours have the potential to cause trouble for travellers, and difficult conditions for revellers as they prepare to depart the Glastonbury festival. The event has been a complete washout, as heavy rain throughout the three-day festival turned Worthy farm into a giant quagmire. The Environment Agency has two flood watches in place - the River Leam between Marton and Leamington Spa in Warwickshire and River Wreake from Frisby to Syston. Marco Petagna, forecaster for MeteoGroup UK, the weather division of the Press Association, said parts of England had received heavy showers on Sunday, with nearly half and inch falling in one hour in Hereford. He said the soaking the country has received in the past week is unusual for June, as are the temperatures - which dropped to 12 to 18C across the country.
