A message on its website says:
Extremely high winds are expected during the early morning of Monday 28th October. As a result, Network Rail has declared that there is a high risk of trees and debris falling onto railway lines and as a consequence, it may be unsafe to run trains while the winds persist.
“Therefore, Southern and Gatwick Express services will not run tomorrow morning until it has been declared safe to do so.
Passengers are advised to check with National Rail Enquiries on 08457 48 49 50 or visit www.nationalrail.co.uk for up to date information as the morning progresses.”
