After spending the night in his car on the M5, Simon Clarke said there was no anger among motorists but it was "not nice" because there were no facilities.
BBC broadcast meteorologist Matt Taylor said there was a slim risk of torrential rain in the south and south east of England and that overall rain would remain heavy in the Midlands and north of England.
He also warned that further flooding could occur as Friday's heavy rain continued to filter through the river system.
