Weather: Floods In Wales Cause Power Cuts And Train Delays

Media caption, Many areas across Wales are experiencing storm disruption following high winds and heavy rain overnight.

Stormy weather has caused disruption in south Wales including power cuts, flooding and train delays.

The National Grid said about 600 homes, mainly in Newport, have no power.

South Wales Fire and Rescue Service said the areas worst affected by flooding were Porth and Pontypridd in Rhondda Cynon Taf.

Earlier on Thursday, Transport For Wales (TfW) said four railway lines were blocked, including Cardiff Central to Caerphilly.

These services blocked due to flooding included Pontypridd to Treherbert, Abercynon to Aberdare, and Bridgend to Llantwit Major, but the Porth and Pontypridd service is running, TfW said.

Great Western Railway also said its services were affected due to heavy rain.

The fire service added that a number of hillside and low-lying properties have been affected from run-off water and blocked culverts – these are tunnels which drain water away.

A yellow rain warning remains place until 17:00 GMT on Thursday across 16 of Wales’ 22 counties.

Meanwhile, wind speeds are predicted to increase and a yellow warning for high winds up to 70mph (112km/h) has been issued in Conwy, Gwynedd and Anglesey between 15:00 on Thursday and 03:00 on Friday.

Group manager and head of community safety at South Wales Fire and Rescue Service, Bleddyn Jones said: “The incident in Tylorstown involves a blocked culvert which has affected around 20 to 25 properties, and we are hearing that ports around the Power Station hill area near Pontypridd, there’s some localised flooding in that area.”

Natural Resources Wales has more than 40 flood alerts in place, but said there was no widespread flooding from major rivers at present.

Leader of Rhondda Cynon Taf council, Andrew Morgan, said: “So far all the culverts that we’ve spent millions of pounds upgrading since Storm Dennis have upheld.

“If your journey is not urgent, stay off the roads for the next few hours so the highway crews and emergency services have a chance to respond.”

Guto Davies from Clwb y Bont in Pontypridd said there was about 2in (5cm) of water in the club and he had erected barriers to stop more getting in.

He added: “We received many flood alerts, but until we get a flood warning we don’t put the barriers up. That system hasn’t worked for us and that’s worrying and disappointing.

“Since February 2020, we partially reopened then fully reopened in November – barely three months and it’s flooded again.”

Head of operations south central at Natural Resources Wales (NRW), Mike Evans, said: “We’ve been suffering from quite severe conditions on top of several weeks of rainfall.

“The biggest impact is there is a lot of surface water around so I advise people to be very careful before leaving the house.”

Several of Stagecoach South Wales’ services have been cancelled or delayed.

Dairy farmer Abi Reader from Wenvoe, Vale of Glamorgan, told BBC Radio Wales Breakfast that it had been “a wild night”.

She added: “We’ve had electricity flickering on and off. The milking parlour had about a foot of water in it which we’ve had to pump out.”

Meanwhile, the National Grid said power outages were mainly affecting about 450 homes in Newport as well as some in Penarth, Vale of Glamorgan, Llanelli, Carmarthenshire and Kenfig Hill, Bridgend county.

Among the flood warnings in place from NRW, there are eight for stretches of the River Severn in north Powys, four for different stretches of the River Taff from Merthyr Tydfil to Pontcanna in Cardiff, and three on the River Cynon.

The M48 Severn Bridge is closed in both directions between Chepstow and Aust in Gloucestershire.

The heavy rain has caused one of the main roads in Chepstow, Welsh Street, to close between the town centre and the comprehensive school.

The A4061, Bwlch Mountain Road, is partially blocked in both directions between B4223 Pen-Twyn Road and Haul Bryn in Nantymoel, Rhondda Cynon Taf, due to a landslip.

Meanwhile, Cardiff council has warned that water levels are extremely high at the level crossing on Michaelston Road over the River Ely at St Fagans and urged people to avoid the area.

TfW said it was experiencing “disruption across the network” in south Wales and advised passengers to check before travelling.
