The Met Office has issued further weather warnings for huge downpours as large parts of the UK brace for a deluge.
It comes after 40 flood alerts were issued for much of the south coast following torrential downpours.
The worst could be yet to come though, with forcasters prompted to send out further weather warnings.
A yellow warning for rain and wind is in place across London and the south east of England, as well as parts of the south west.
The warning is in place from 6pm tonight through until midnights, with a short period of very heavy rain and strong winds likely to cause some disruption.
There's also a weather warning issued for Northern Ireland and Wales, covering the same timespan, with residents urged that temporary flooding on roads could lead to delays.
Meanwhile, a yellow warning is also in place for Dumfries, Galloway and Lothian in Scotland from 3pm through until midnight.
Brits woke up to torrential downpours this morning with numerous flood alerts in place.
Five "act now warnings" - which signal flooding is expected at any time - were issued around areas including Eastbourne, Lewes, Burgess Hill and the Isle of Wight.
Cowbeech in East Sussex, for example, had recorded 34mm of rain in just 24 hours last night, with river levels possibly not returning to normal until tomorrow.
Met Office forecaster Simon Partridge warned there is more to come.
"We are expecting to see 15 to 25mm of rain but it's basically mainly associated with some heavy showers," he said.
"So a lot of it is to cover the potential for some very tricky driving conditions tomorrow morning, being obviously Monday morning so one of the busiest."
