Fallen trees and flooding from the storm overnight have caused major problems on the transport network this morning.

Southern trains said it had cancelled all services until further notice because it is unable to properly assess the damage from the storm until daylight. It does not expect trains to run again until much later this morning.

First Capital Connect is advising people to only travel if necessary. It has suspended Thameslink services on the Wimbledon/Sutton Loop until further notice due to Network Rail testing the route to make sure it is safe to run trains.

South West Trains has said it will not be running trains on any routes until at least 10am.

Trams have also been affected with the Croydon tramlink service suspended between Lloyd Park and New Addington due to damage caused by flooding at Addington Village.

The road network has also been affected by flooding and fallen trees.

In Croydon, the A232 Shirley Road has been closed both ways due to flooding between A232 Addiscombe Road and A232 Wickham Road.

The A212 Wellesley Road was closed in both directions due to an accident between Station Road and A222 St James's Road at about midnight, but it reopened shortly after 7am.

Marlpit Lane, Coulsdon has been closed due to flooding between Chaldon Way and B2030 Coulsdon Road.

In Cheam a fallen tree closed A232 High Street in both ways overnight at A217 St Dunstan's Hill but this has now been reported as cleared.

Rail companies are advising people to check their websites and the national rail website before attempting to travel.

A statement from Southern trains on their website this morning said: "The stormy weather overnight into this morning has caused considerable difficulties for our rail network and the surrounding road network.

"As a result, several lines of route are suffering from a combination of flooding, blockages from fallen trees, power supply failure or potential landslips.

"We will not be able to gauge the full extent of this damage or the prospect for operating services safely until daylight. Currently we are working closely with our colleagues in Network Rail to prioritise the clearing and proving of routes to be safe before trains can operate.

"This means that train services are suspended until this work is complete and we do not expect this to happen until much later this morning."

"There will be no trains on the Wimbledon/Sutton Loop until further notice due to Network Rail testing the route to make sure it is safe to run trains."

"Services are likely to remain disrupted for the rest of the day so anyone travelling is advised to do so as early as possible to ensure they reach their destination on Christmas Eve."
