As many as 11 UK cities could experience disruption from heavy rain and flooding including travel problems and power cuts as Storm Bert wreaks further havoc on Sunday.

Right now, the one Met Office urges people to prepare for potential flooding and the knock-on effects it could have in several major cities.

Cities mostly in the south have been issued a yellow weather warning for heavy rain, including Portsmouth, Oxford, Bath, Gloucester, Exeter, Bristol, Plymouth and Truro as well as Brighton.

In South Wales, both Swansea and Cardiff are affected.

The rest of the UK is not yet under a rain warning, but rain is still forecast for many cities, including London, Leeds, Newcastle and Manchester.

The Met Office said in its forecast: “Heavy rainfall will affect large parts of the UK this weekend. Rain is expected to develop on Saturday morning across south-west and southern England, becoming particularly heavy and persistent overnight and into Sunday. Accumulations of 50-75mm are expected to fall quite widely during this time.

“There is a chance that some places across Dartmoor could see 100-150mm. Strong southerly winds will accompany the heavy rain and could locally worsen the effects. The rain will be less extensive on Sunday as it clears erratically eastwards.”

In its advice on the yellow weather warning, the Met Office urges households to be prepared for the potential effects of flooding.

It adds: “Check whether your property may be at risk of flooding. If so, consider preparing a flood plan and emergency flood kit.

“Give yourself the best chance of avoiding delays by checking road conditions if you’re driving, or bus and train timetables, changing your travel plans if necessary.

“People cope better with power outages when they prepare for them in advance. It’s easy to do; consider packing flashlights and batteries, a cell phone battery and other essentials.”

Dozens of red flood warnings have been issued in England, meaning flooding is expected and residents and businesses should “act now”, according to the Environment Agency (EA).

The Met Office said Storm Bert is likely to cause “dangerous coastal conditions” and disruption across southern England and parts of Wales until 9pm on Sunday with a yellow wind warning in place.

The Met also issued a yellow weather warning for Sunday across parts of south-east Wales and Herefordshire, which is active until 1pm.

The National Weather Service has warned that some communities could be cut off by flooded roads, particularly in the west of England.

Heavy and persistent rain will hit south-west England into Sunday, with a chance that some places across Dartmoor could see 100-150mm of rainfall, Met Office said.

Strong winds will exacerbate the effects of heavy rain across the country.

Travel disruption will continue into Sunday and ferry operator DFDS has suspended services on some routes until Monday, including departures from Newhaven to Dieppe.

It comes after as much as 64.4mm of rain fell in Capel Curig, North Wales, in 12 hours on Saturday and gusts of up to 82km/h were recorded in the Welsh village.

A man in his 60s died after a tree fell on a car on the A34 near Winchester, Hampshire Police said.

The force was called at 7.47am on Saturday to the southbound carriageway between Kings Worthy and Winnall and found the driver of a black Mercedes E350 dead at the scene. The police are investigating whether the incident was connected to the storm.

Two other fatal collisions occurred as the storm took hold in England.
