A weather warning for snow and ice has been extended as an Arctic blast heads towards the UK.

Spells of snow on Wednesday may cause travel disruption tomorrow and into Thursday morning.

The Met Office has warned of delays on roads that could strand vehicles and passengers, as well as longer journey times on bus and train services.

The weather warning, which in place for all of Sussex, now lasts from midnight tomorrow until 9am on Thursday.

A spokesman for the Met Office said that the warning has also been extended to cover a larger part of southern England.

He said: “The warning has also been extended into Thursday, primarily to include residual ice impacts that may persist into the morning travel period.”

Dale Hipkiss, national network manager at National Highways, urged people to plan their journeys ahead of time, listen to weather forecasts, and adjust driving behaviour according to the conditions on the roads.

He said: “Freezing conditions bring so many hazards such as snow and ice, so take every possible step to understand your journey in advance and allow lots of extra time when travelling to prepare for the unexpected.

“Keeping a kit of essential items like a torch and warm clothes in your vehicle can be vital in case you and your passengers become stranded.”
