The government has issued a flood warning for much of the East Kent coast tonight.
Flooding is expected two hours either side of high tide tonight, which equates to between about 10.25pm today and 2.25am tomorrow.
Telling residents "flooding is possible - be prepared", government guidance on the surge reads: "This Flood Alert has been issued as large tidal surge is expected to affect the foreshore due to high spring tides.
"Flooding is forecast to affect locations near the coast throughout this area, with low lying land expected to be most affected, particularly around Sandgate esplanade, Dover Marina and St Margaret’s Bay.
"Coastal conditions might continue for the next few days during the high spring tides period. Please be careful in areas along beaches, promenades, coastal footpaths during the period of concern, and avoid any flood water.
"We will continue to monitor this situation, and have staff prepared to respond if needed.
"Detailed information for those who need it: the total water level for Dover is forecast to be 3.68 m AOD at 00:25 BST on 09/04/20."
This mean the water level will be more than 3.5 metres above its usual height.
