Commuters have been urged to check journeys before travelling this morning after heavy rainfall overnight left train lines and roads submerged in water.
Five Tube lines have already been hit by flooding, with the Piccadilly, London Overground, District and Metropolitan all part suspended. There are also severe delays on the Bakerloo line.
National Rail has warned passengers that services across England and Wales may be affected after the Met Office warned that more than a month’s rain could fall in some areas on Monday.
Severe weather is affecting Great Northern, Gatwick Express, Southern and Thameslink routes. The disruption is expected to last until at least 7.30am.
On the roads, National Highways has warned drivers to consider alternative routes into London, with the A3 northbound entry slip road from the M25 at junction 10 roundabout closed after flooding.
