Storm Callum has begun wreaking havoc across the UK, bringing torrential rain and gale force winds of up to 76mph to some areas, and prompting warnings of flooding, power cuts and travel disruption.
The severe weather has already hit some parts of the country hard, with Western Power Distribution saying more than 950 homes had been left without electricity in south-west England, while almost 100 were affected in south Wales.
Homes and businesses in Northern Ireland also suffered a power loss, and both flights and rail services have experienced disruption as weather alerts have been issued.
The Met Office has issued a 36-hour amber warning for much of south Wales, advising that the heavy rainfall could present a risk to life. Yellow warnings are also in place for the rest of Wales, along with large parts of northern England and southern Scotland.
Coastal areas are expected to be the worst hit, with some communities at risk of being cut off by flooded roads.
The strong gales are also expected to lead to widespread travel disruption, and several flights and trains have already been cancelled in some areas.

The Met Office meteorologist Alex Burkhill said: “We’ve got a wind warning which covers all the western side of the UK.
“That in itself is likely to bring disruption to roads and there is likely to be some bridge closures and power outages.
“We also have yellow and amber warnings of between 50mm and 150mm of rain for Wales. That’s quite a substantial amount of rain to come and could bring flooding.”
Sioned Warrell, natural resources Wales duty tactical manager, added: “The current forecasted rain could cause flooding this week, especially in south and west Wales, and we are urging people to prepare themselves.”
Dozens of flights at Belfast City and Dublin Airports have been cancelled, with the airline Flybe cancelling all departures from 6am to 9:30am this morning, apart from flight BE731 to Leeds Bradford and BE680 to Edinburgh which have been delayed until later in the day.
Flybe flights in and out of Newquay in Cornwall were also cancelled this morning, with customers affected by the cancellations advised not to travel to the airport.
A spokesperson for Flybe said: “The safety of its passengers and crew is our number one priority and Flybe will, as always, do everything possible to minimise any disruption.
“Customers are asked to continue to check the airline’s ‘live’ flight information for the latest updates.”
