Wet and windy weather has been causing havoc for commuters across the UK this morning as flash flooding closed roads and cancelled public transport. Meanwhile, forecasters have warned Brits to 'get their ice scrapers out' and prepare for frost this week as temperatures are due to drop to -2C in parts of the UK tomorrow. The rain has mostly affected the South East, where earlier today flooding blocked sections of the M25, A41 and A1 in London and caused long delays on the Underground.
