UK weather: Heathrow flights cancelled as freezing fog causes travel disruption

Yellow weather warning in place for large area of England after extremely cold temperatures overnight

Dozens of flights out of the UK’s largest airport have been cancelled as freezing fog causes disruption to transport networks. Forecasters warned that much of south-eastern England would be hit by travel delays as a patch of cold weather moves in.

The Met Office said an area stretching from London almost to the Humber was at risk and issued a yellow warning – the least severe. Parts of south-eastern England, including most of East Anglia and the home counties, as well as much of the east Midlands, were likely to be affected, they said.
