Winds of 70mph are set to strike this afternoon, a rail operator has warned, with services set to be affected.

The strong gusts are expected to start at 4pm today (Monday) and continue until tomorrow morning.

Rail firm First Capital Connect is expecting the wind to have a major impact on services.

A statement on the firm’s website said: “Severe weather is expected to impact our network over the coming days.

“Winds of 70mph are expected from 16.00 Monday to 10.00 Tuesday and trains will be running at reduced speed to reduce the safety risk associated with trees and other debris being blown on to the railway lines.

“We advise you to travel on Monday and Tuesday only if your journey is necessary.”

On the Great Northern Route, which serves stations including Welwyn Garden City, Hatfield, Potters Bar, Brookmans Park, Knebworth, rail chiefs have warned the forecast winds are likely to cause further disruption.

Evening peak restrictions will be lifted.
