Tony Evans, senior watch manager at Dover Coastguard, said: “With one of the worst tidal surges we've seen in recent years, we would urge members of the public to take extra care along our coastline at this time.
“These types of conditions, with choppy seas and large waves, are likely to be with us for a few days yet, so please don't take risks. If you do get into difficulty, or spot someone else in trouble, call 999 straight away and ask for the Coastguard.”
The Environment Agency (EA) said it had spent today checking flood defences.
Jason Wakeford, a spokesman for the (EA), said: "Some 800,000 properties have been protected by the defences put in place in the last six decades and we have issued 120,000 warnings to individual properties.
"It is quite clear from those numbers that events like this are hugely dangerous - the 1953 flood claimed thousands of lives so alerts and warnings are very important to prevent such a disaster happening again.
"In places across the east coast sea levels were higher than in 1953. However, this time we had much better protection in place."
Mr Wakeford said the Thames Barrier had faced the biggest tide since it opened in 1982 and would be closing again at 11.15am after being shut overnight and reopened.
