A severe weather warning for rain in East Sussex has been issued by the Met Office for today (Monday January 6) and tomorrow (Tuesday January 7).
It said heavy showers, some of them combined with hail and thunder, would continue to sweep across parts of Southern and Southeastern England at times through the rest of Monday and Tuesday.
Residents should be aware of the risk of further localised flooding.
The next 36 to 48 hours will see bands of showers running into Southern coastal counties and across the Southeast of England in particular.
These have the potential to produce intense bursts of rain, quickly leading to localised impacts given the saturated ground. The Met Office said it would not rain constantly, with a significant drier interlude for some parts through the middle of Monday.
The county is on a yellow alert, which is lease serious weather warning from the Met Office.
The next level up is amber, with the most serious red.
The rivers Cuckmere and Ouse are currently on a flood alert from the Environment Agency.
Areas included in the flood alert zone are the Upper Ouse and tributaries from Slaugham to Barcombe Mills, Lower Ouse and tributaries from Barcombe Mills to Newhaven Harbour and the Cuckmere River and tributaries from Vines Cross to Exceat Bridge.
