People should expect disruption to travel, isolated flooding and possible power outages this weekend as heavy rain is due to fall.
The Met Office have issued a yellow weather warning for rain in Kent from noon to midnight on Sunday, September 19.
Sunday is set to start out fairly dry but a band of showers edging eastwards will become more active to bring outbreaks of heavy rain or showers and isolated thunderstorms, which could result in 30-40 mm falling in a short space of time.
The Environment Agency said: "We are preparing for the possibility of heavy, isolated rainfall on Sunday.
"This high intensity rain may cause localised surface water flooding as drainage systems may not be able to cope, particularly in more built-up areas.
"There is also the potential for flooding from fast responding rivers, however we are currently unable to predict the specific locations that may be impacted.
"Not all areas will be affected. We are actively monitoring the weather forecast and our operational staff will continue to proactively clear debris screens in order to help keep the rivers flowing freely."
This is the second yellow warning for rain this week, with a similar warning put in place on Wednesday.
