Sussex residents have been warned of travel disruption with a weather warning issued for snow for later in the week.

A yellow weather warning has been issued by the Met Office for most of the county, as well as most of southern England and South Wales for Wednesday for snow as a band of Arctic air meets Atlantic air pushing north.

The weather service has warned of a chance of travel delays on roads, cancelled rail or air travel, and a “slight chance that some rural communities could become cut off” by the wintry conditions.

Power cuts could also occur due to the snowfall, the Met Office warned.

A spokesman for the Met Office said: “Spells of snow reaching parts of South West England late on Tuesday evening will then spread north during the early hours of Wednesday before clearing away eastwards during Wednesday daytime.

“Many parts can expect accumulations of one to two centimetres of snow whilst over higher parts of South West England, especially Bodmin Moor, Dartmoor and Exmoor, along the hills and mountains of south Wales five to ten centimetres of snow is likely for some.

“Untreated surfaces are also expected to become icy.”

It comes just hours after the Met Office issued a yellow weather warning for parts of northern Sussex for snow and ice from later this evening and into tomorrow morning.

BBC weather forecaster Carol Kirkwood said that, while uncertainty remains over the forecast for later this week, heavy snow could hit parts of southern England early on Wednesday morning.

She said: “At the moment, we think it will come in over southern areas of England for a time, and then it will revert back to cloud and rain.

“Later, we will see more rain and snow coming in across the South West.

“As we move towards the end of the week, it will turn that little bit milder in the south.”

Temperatures are expected to rise to around 11C in the latter half of the week, but conditions will be wet with heavy rain forecast.
