BBC Weather warned the risk of flash floods over the weekend will cause warnings to remain active through the weekend as a new wave of heavy showers and gusty winds readies to pummel the UK. A flurry of flood warnings has been issued since Friday afternoon because of Storm Elsa moving in across the UK after wreaking havoc on Ireland's western coast. BBC Weather forecaster Alina Jenkins said: "Some places have had nearly a month’s worth of rain in just a few days.
"Not surprisingly, the flood warnings are continuing to rise – we’ve now got an excess of 100 flood warnings across England, we’ve got two in Wales and there is more rain to come.
"We’ve had some heavy showers around this morning, they’ve been merging to give a longer spell of rain, a rumble of thunder, a flash of lighting all down to this feature her which is clearing northern-eastwards.
"But waiting in the wings, more rain to come, initially across southwest England and south Wales through this evening and overnight and then pushing its way northern-eastwards."
The BBC Weather meteorologist said the heavy rains will clear during the morning easing into scattered showers before a new deluge moves in across Cornwall, South Wales, and southern England.
She continued: "The heavy showers slowly starting to pull away from northern and western Scotland but this area of rain and showers has been quite heavy as it pushed its way through England and Wales.
"It will soon be out of the way and, actually, for much of the UK, it’s a day of sunshine and showers. Quite a great day for Northern Ireland because we had some dense patches of fog with poor visibility that lifted but I think we’ll keep a lot of cloud.
"Later in the day, that rain starts to push into southwest England and south Wales – 10C or 11C in the far south of England, just 5C or 6C in the far north of Scotland and somewhere in-between across northern England, Northern Ireland and Wales."
Ms Jenkins warned rains are due to intensify overnight into Sunday, when more scattered showers will bring in further rain throughout the UK alongside gustier winds.
She added: "Through this evening and overnight this rain starts to track its way northern-eastwards initially across southern England and Wales, then through the Midlands, southeast England, East Anglia.
"Winds will be strengthening as well, some gusty winds on Channel coasts and also for the Channel Islands."
However, the BBC Weather forecaster said conditions should slowly improve as we head into Christmas week, with more spars rainfall on Monday and Christmas Eve.
Christmas Day is forecasted to be brighter and drier through England compared to the start of the week but conditions are expected to "turn wet again later."
But Scotland could still be on track for a white Christmas as temperatures are expected to plummet to -4C.
Met Office forecaster Bonnie Diamond said: "On Christmas Day there is the potential for snow to fall over high ground in Scotland.
"A light flurry may be expected."
John Hammond, chief meteorologist for Weathertrending told The Sun Online: "It’s a very volatile weather situation we’re heading into over the next few days.
"Chilly air will be sweeping down from the north, meeting milder air to the south. Where these two meet, there’s the chance that an area of low pressure will form somewhere across the heart of the UK.
"Where this happens there’ll be rain, but the air may just be chilly enough on the northern boundary for this to turn to snow.”
