Heavy rain, winds and “unseasonably cold” weather are hitting parts of the UK, with flood and weather warnings in place. Some train services in the south-east of England have been cancelled. A yellow warning for heavy rain and strong winds is in place for southern and eastern parts of England for the whole of Monday. Forecasters warned some places could see more than a month’s rainfall in one day. A flood warning – which means flooding is expected – is in place along the River Nene, east of Peterborough. The Environment Agency issued a total of 31 flood alerts – meaning flooding is possible – across England. Some early morning services on Southeastern Railway were cancelled and Southern Rail passengers also saw disruption because of speed restrictions due to the weather. Thameslink and Gatwick Express services also said they could be affected and London City Airport said some flights could be delayed or cancelled. The Met Office had warned commuters that flooding could result in poor driving conditions and delays to bus and train services. The wet and windy weather is the result of an area of low pressure moving northwards overnight on Sunday. It will feel “unseasonably cold” for the time of year, the BBC Weather Centre said, with maximum temperatures about 6 to 7C in these areas, but feeling much colder under the rain and wind. High ground – like the Chilterns and the Cotswolds – could even see sleet and snow, although it will not settle. During the course of Monday, affected areas are likely to see rainfall of 25-35mm. Up to 80mm is possible across parts of Norfolk and the North Downs (average monthly rainfall for Norfolk in April is 44mm). There will be strong northerly winds too, with gales around eastern coasts with gusts of 40-45mph inland and up to 50-55mph along exposed coasts. This is a relatively unusual wind direction for the time of year, the Weather Centre added, and trees being in full leaf could cause some problems.
