Heavy rain and flooding bringing possible danger to life have been forecast for parts of Wales and England on Tuesday as Storm Bram hits the UK.
Amber warnings have been issued by the Met Office for large areas of South Wales and Cornwall from midnight to 10am on Tuesday.
Heavy rain will build from Monday evening, continuing through the night and into Tuesday morning, with between 50mm (2 inches) and 75mm (3 inches) falling over around nine hours.

As much as 100mm (4 inches) may fall in a few exposed locations, forecasters said.
Deep or fast-flowing floodwaters are possible, causing damage to buildings and flooding homes and businesses, with roads cut off and travel disrupted.
Parts of northwest Scotland were already under an amber warning for "very strong" winds reaching as high as 90mph (145kmh) from 4pm until the end of the day.
Flying debris "could result in a danger to life" - and there could be damage to buildings and homes along with the risk of roofs being "blown off" due to the "very strong and disruptive winds", the Met Office warned.
Forecasters added there was the potential for large waves and beach material "being thrown" across sea fronts, roads and properties.
Storm Bram, named by the Irish weather service, could bring more than half a month's rainfall to some parts of the UK in just a 24-hour period, the agency said.
Yellow warnings for rain have also been issued for most of Wales, the South West and the central belt of Scotland, the Met Office said.
Yellow and orange warnings are in place across Ireland on Monday and Tuesday, with "very strong to gale force" winds forecast on Tuesday.
The Met Office said strong winds forecast from Monday evening through until Wednesday could cause disruption, with gusts of 50-60mph predicted widely and 70-80mph in some places.
A yellow weather warning for rain comes into force from 6pm on Monday, and will be in place until 2pm on Tuesday, covering parts of southwest England and Wales, and stretching to parts of Herefordshire and Hampshire.
The Met Office has also issued a yellow warning for high winds from Dorset to Cornwall and up to North Wales, in place from 10pm on Monday until 4pm on Tuesday.
It said transport networks could face disruption, with delays for high-sided vehicles on exposed routes and bridges, and coastal roads and seafronts affected by spray and large waves. Power outages are also possible.
From 6pm on Monday, up to 40mm of rain could fall in some areas, with 60-80mm of rain over Dartmoor and high ground in South Wales, which would amount to more than half the average monthly rainfall in December.
The predicted rainfall across southwest England and South Wales is expected to hit already saturated ground and could lead to difficult travel conditions.
There are also further yellow warnings for wind and rain on Tuesday across Northern Ireland, Scotland, Wales and northern England.
Yellow warnings for wind have been issued for Scotland and parts of northern England on Wednesday.
The Met Office's deputy chief meteorologist, Steven Keates, said: "A deepening area of low pressure will approach the UK from the southwest later on Monday, bringing with it heavy rain and strong winds, which are likely to affect the UK between late Monday and early Wednesday.
"The exact track, depth and timings of this low are uncertain, which makes it harder to determine where will be most impacted by strong winds and/or heavy rain.
"This system has the potential to cause disruption, and severe weather warnings are likely to be issued over the weekend as details become clearer. We therefore urge people to keep up-to-date with the latest Met Office forecast."

Sky News meteorologist Dr Christopher England warned many areas could face disruption from "damaging gusts".
"There could also be ferry disruption and that even outside the warning areas, potentially damaging gusts of over 50mph are possible," he said.
"It only takes one tree falling in the wrong place at the wrong time to have a significant impact."
The Met Office said the rest of the month remained unsettled, with further periods of low pressure predicted.
It said it is too early to provide an accurate forecast for the Christmas period.
