The Met Office has issued an update to a weather alert for snow across Sussex tomorrow.

A yellow weather warning for snow and ice is in place for the entire county tomorrow evening, with the BBC forecasting wintery showers across parts of Sussex.

Eastbourne, in particular, is expected to see prolonged periods of snowfall from around 7pm until around 3am the following morning.

However, the national weather agency has pushed back the start of its alert, which also covers most of south-east England and London, to 6pm tomorrow.

The Met Office warn that snow and ice could lead to a risk of travel disruption, especially for commuters on Monday morning, with as much as ten centimetres of snow possible in some places.

“The areas most likely to be affected are in Kent and Sussex, with the higher ground here most exposed,” a spokesman for the weather service said.

The cold snap that has gripped the country in recent days is expected to last well into the coming week.

Met Office chief meteorologist Steve Willington said: “It is staying cold with daytime temperatures remaining only a few degrees above freezing in many places over the coming days and overnight temperatures dropping to -10C or lower in isolated spots.

“Although below average, these temperatures are not that unusual for this time of year.

“There is still a risk we could see some freezing fog in places, particularly southern England, especially for Sunday and Monday mornings. There is also a small risk of a band of sleet or snow moving into the far south-east on Sunday.

“If this happens, it could potentially bring some disruption, especially to rush hour on Monday.”
