New forecasts show the exact day parts of the UK could be hit by freezing rain, which can leave roads and runways covered in slippery ice

The Met Office has warned of flooding, flight and public transport delays, and a “danger to life” from fast-flowing rivers in parts of the UK. The forecaster said flooding to homes and businesses and delays to train and bus services are likely in the south-west of England on Wednesday.

The UK is forecast to experience a significant freeze in the coming weeks, with five counties expected to be hit the hardest.

The Met Office says temperatures are set to tumble in the coming days and overnight frost and fog, or freezing fog, is likely too as the weather looks unsettled before Christmas

More settled but colder conditions are expected, with the potential for wintry showers in places, the Met Office said.

The weather phenomenon, which is mostly common in the US, will hit several areas of the country, the maps have suggested.
