Met Office issues upgraded amber alert for Cardigan area

There are limited replacement buses but road closures are also likely. The alerts mean flooding is possible rather than expected, with high river levels and standing water on roads likely.

"South Wales in particular is a cause for concern, with an amber warning in force", Met Office meteorologist Aidan McGivern warned.

Rivers, including the Towy in Wales, burst their banks and homes were left without power as the west of Britain was lashed with rainfall, with parts of south-Wales severely affected, with images showing towns partially submerged across the region.

Rail services to Drogheda, Dundalk and Belfast have been suspended because of a tree on the line at Donabate in Dublin.

The Scottish Environment Protection Agency issued five flood alerts for Friday in Argyll and Bute, Ayrshire and Arran, Dumfries and Galloway, Scottish Borders, Skye and Lochaber and Orkney.

"Natural Resources Wales has issued flood alerts for the Pembrokeshire coast due to a low pressure system bringing tidal surges, strong winds and large waves on top of high astronomical tide period" he continued.

There is now a yellow warning for wind in place for Northern Ireland.

Edinburgh will then see heavy rain continuously throughout the day on Saturday, only easing towards late evening. "We've got a wind warning which covers all the western side of the UK".

James Nicholas of Arriva Trains Wales said: "There is significant rain expected this weekend across Wales coupled with high winds and very high tides, particularly up on the Cambrian Coast - linking in to Shrewsbury".

Monsoon-like weather saw the United Kingdom deluged with rain bringing flooding chaos. "In addition, leaves and twigs, brought down by the wind, could block drains and culverts, increasing the likelihood of flooding".

Windsor, the scene of Friday's royal wedding, looks set to escape the worst of the storm.

The south-east is expected to be blustery but stay "quite dry", with temperatures possibly reaching up to 24C (75F).
