Heavy rain is sweeping across central England, increasing the risk of further flooding.Flash floods have already hit North Yorkshire and dozens of residents were evacuated when Skeeby Beck burst its banks, causing flooding in Gilling West, Hartforth, Melsonby, Ravensworth, Kirby Hill and Middleton Tyas near Richmond.The downpours started in southern England in the early hours and are expected to last most of the day.Central England and Wales are likely to see heavy rain during the day, with up to four inches predicted to fall in a short period.The north of the country is likely to have a showery day before heavy rain at night.Other areas at risk include the South West and eastern parts of Wales, where there could be up to two inches of rain.Keith Groves, head of forecasting at the Met Office, said: "When you get such heavy rainfall in such a short time then there is a greater risk of flooding."Areas such as Birmingham, the M5/M4 corridor and the Cotswolds are at the greatest risk of the most rain, but anywhere in England and Wales could see torrential downpours at some stage today."The Highways Agency warned rain and spray can reduce visibility and more than double the distance it takes to stop.A spokesman said: "Drivers are advised to use headlights and keep well back from the vehicle in front."Drivers are also advised to check for delays and weather problems before they set off and to listen to radio bulletins while they are on the road.© Independent Television News Limited 2007.
