Storm Bert is bringing further widespread disruption, with public transport badly affected after “devastating” flooding over the weekend.

Several rail operators cancelled services on Monday while more than 160 flood warnings remain in place.

Hundreds of homes were left under water, roads were turned into rivers and winds of more than 80mph were recorded across parts of the UK.

In England, a severe flood warning, meaning there is danger to life, has been issued for Billing Aquadrome and surrounding parks next to the River Nene in Northampton.

Two severe flood warnings previously issued for the River Monnow in south-east Wales for Monmouth and Skenfrith, have been lowered to warnings, meaning flooding is expected.

More than 150 flood warnings and 197 flood alerts have been issued by the Environment Agency in England, with a further 10 flood warnings and 21 flood alerts in place in Wales.

Rail passengers have been urged not to travel between Broxbourne, Hertfordshire, and Stansted Airport, after several fallen trees damaged the electrical overhead wires. No trains are expected to run until 5pm.

London Northwestern Railway reported that no rail services would operate through Northampton station due to the River Nene bursting its banks.

Southern, which runs rail services across the south-east of England, said some services on Monday will be cancelled or revised because of forecast severe weather, including on its London network and the West Coastway between Havant and Southampton.

Great Western Railways warned passengers not to travel as it suspended services on all key routes because of flooding and fallen trees.

Transport for Wales said all services between Pontypridd and Treherbert, Aberdare and Merthyr Tydfil are currently cancelled with disruption expected throughout Monday.

It added lines are closed between Hereford and Abergavenny due to a landslip with no rail replacement service available, while no services will run between Shrewsbury and Swansea until at least 12pm.

Services between Lancaster and Barrow-in-Furness in Lancashire will not run until Friday due to heavy flooding, with rail replacement transport extending journey times by up to an hour.

Southwestern Railway said all lines between Fareham and Southampton Central have now reopened after the removal of a tree, but services will be disrupted until 11am.

ScotRail advised customers speed restrictions will be in place on many of its routes leading to longer-than-normal journey times.

On the roads, the A5 is closed in both directions between the A508 and the junction with the A43 because of flooding as of Monday morning.

A lane on the A14 eastbound between junctions J16 Catworth and J18 Spaldwick West is also shut with disruption expected to clear between 8.45am and 9am.

Welsh Water has issued a “boil water” notice to customers in 10 areas in South Wales, advising that their tap water may be contaminated because of flooding and must be boiled until further notice.

In a post on X, Canterbury Cathedral in Kent said it would be closed until midday on Monday because of the effects of the storm.

Storm Bert is “only just slowly pulling away” from the UK on Monday, meaning an “unsettled start to the day”, according to the Met Office website.

In an online forecast, Met Office meteorologist Greg Dewhurst said: “The day ahead is generally a mixture of sunny spells and showers.”

Frequent showers are expected in Scotland, Northern Ireland, northern England, Wales and the West Country, with sunnier, drier weather across parts of the Midlands and south-east England, he continued.

It will be “a pretty windy afternoon” across the country, with gusts of around 30mph to 40mph which may reach 50mph in parts of Scotland, Mr Dewhurst added.

London and south-east England will experience a top temperature of 11C, with highs of 7C expected in Scotland.

Into the evening, further showers are expected across the country with longer spells of rain and snow on high ground in Scotland, Mr Dewhurst added.

All of the forecaster’s rain warnings ended on Sunday but strong winds persist and rain from high ground will reach rivers, which could disrupt clean-up efforts.

A yellow wind warning remains in place for much of central and western Scotland until 10am, with gusts of up to 70mph likely in exposed areas.

Around 350,000 homes in England lost power during the storm, though most have since been reconnected.

More than 300 flights set to depart from UK airports were cancelled during Storm Bert, aviation analytics firm Cirium said.

Some areas saw in excess of 130mm of rainfall in just 24 hours on Sunday.
