The weekend has started off sunny and unseasonably warm but, it is not going to last.
A yellow weather warning has been issued across Bristol.
The Met Office has warned that severe rain will hit this part of the UK tomorrow (Sunday, September 22).
Wales, the South West and parts of the Midlands and North England will also be affected.
Forecasters have urged people to watch out for localised flooding and be mindful the deluge could cause travel disruption.
It is expected a few homes and businesses will be flooded and power lines could be interrupted by lightening.
Parts of Northern Ireland have also been issued the Yellow weather warning from today and it looks set to continue into tomorrow.
Britain is set to bask in glorious sunshine this weekend with the parts of the UK being hotter than Turkey.
Most of England, Wales and even Scotland will start the day with warm and sunny conditions despite the slight breeze.
But there will be strong and gusty winds in the west part of the country.
Forecasters say temperatures in the southeast are set to hit 26C later today - meaning parts of the UK will be hotter than Turkey.
Met Office Meteorologist Helen Roberts said: "The high pressure continues as we start our weekend.
"So this morning is looking dry and sunny but a little bit of breeze in comparison to recent days.
"Barely a cloud in the sky as start the day for Scotland, Northern Ireland, Wales and most of England, with the exception being that very far south west tip of the country," she told the Express.
There will be wet conditions on Sunday as the remnants of Hurricane Humberto move across the British Isles and bring outbreaks of showery rain in the west.
Ms Roberts continued: "Through this evening, we will just start to see that cloud filters some showers across western parts of the country.
"Some of those showers could be in the heavy side and we may have even hear the odd rumble of thunder as we go through in the early hours of Sunday morning."
