Flood risk as Britain faces wet weekend At this stage floods are unlikely but it cannot be ruled out because the ground is so saturated. The South West and Wales are most at risk. Sunday will see a return to drier weather but is likely to be cold with the risk of wintry showers along the east coast of Britain, forecasters said. Sleet could fall across the South as far as East Anglia. The start of 2013 saw unseasonably warm weather with highs of 13C in parts of Britain last weekend. However, Thursday will mark a change in the weather, with colder and wetter conditions likely at the weekend and at the beginning of next week. Temperatures tomorrow night could fall as low as -1 or -2C in rural areas of the northeast and Yorkshire, while rain is expected to sweep in from the West and spread eastwards as the day goes on. Friday will bring a widespread frost, forecasters said. By Monday, there is a risk of fog and icy patches across the country while wintry showers could affect northern and eastern parts.
