The Environment Agency (EA) has issued six flood warnings for the South East. They say huge tidal surges could top flood defences bring "significant coastal flooding" overnight.
In some places, sea levels could be as high as those during the the devastating floods of 1953, the EA said, although flood defences since then, should provide better protection than 60 years ago.
Flood warnings have been issues for the following areas in Kent.
- Gravesend, Denton and Greenhithe
- The Pfizer Site
- Ash level, Minster marsh and Stodmarsh communities
- Grove Ferry and Plucks Gutter
- Coastal areas from Pegwell Bay to Folkestone
