Parts of Sussex could see travel disruption from wintry showers tomorrow, with a weather warning in place for snow and ice.

The Met Office yellow weather warning covers most of the county and is in place for all of tomorrow.

The weather service has said there is a chance that snowfall will cause travel delays on roads, along with cancelled rail or air travel. Many areas could also see accumulations of up to two centimetres of snow.

The warning covers vast swathes of southern England, as well as most of southern Wales, as the country prepares to face the Arctic blast.

Met Office chief meteorologist Dan Suri said: “Snow, ice and low temperatures are the main themes of this week’s forecast, as the UK comes under the influence of an arctic maritime airmass as cold air moves in from the north.

“Wintry hazards will develop with parts of England and Wales affected by icy patches and snow in places in parts of the south early on Wednesday.”

Light rain is expected in the early hours of tomorrow, turning to sleet at around 3am and then heavy snowfall from 4am.

The wintry showers are forecast to last until around 8am, with cloudier conditions anticipated for the rest of the morning and into early afternoon.

More rain is then expected from around 3pm, turning heavy from 4pm, with sleet forecast across the city from around 7pm until later in the evening.

A yellow weather warning for snow and ice is in place for all of Sussex from midnight tomorrow until 9am on Thursday, with the Met Office warning that the wintry conditions could cause travel disruption.

A spokesman for the weather service said people can expect possible travel delays on roads, which could strand some vehicles and passengers, as well as delays or cancellations to bus and train services and the prospect of power cuts in certain areas.

The weather warning is in place for all of southern England, including London, as well as most of southern Wales.
