Six coastal flood alerts were issued across Kent as the Environment Agency warned that high tides, powerful waves and unsettled weather could cause flooding in exposed seaside communities overnight and into Monday morning.
The alerts, published on Sunday 25 October 2026, covered extensive stretches of the Kent coastline, including Dover, Folkestone, Ramsgate, Deal, Whitstable, Herne Bay, Margate, the Isle of Sheppey, the Medway estuary and the North Kent coast.
The warnings followed a weekend of strong winds and disruption, with rough seas and elevated tidal conditions increasing the risk of water reaching coastal roads, promenades, car parks and footpaths.
The Environment Agency warned that some exposed locations could experience flooding around high tide, particularly where waves overtopped sea defences.
Residents, motorists and people visiting the coast were urged to remain cautious and avoid getting too close to the water.
Six Areas of Kent Covered by Coastal Flood Alerts
The Environment Agency issued separate alerts for six coastal areas:
1. Dover and Folkestone
The alert covering the coast from St Margaret’s at Cliffe to Sandgate included the Dover and Folkestone coastline.
Flooding was possible between approximately 8.45pm on Sunday 25 October and 12.45am on Monday 26 October.
People using exposed coastal routes were advised to remain alert to the risk of water reaching roads and pedestrian areas.
2. Ramsgate, Sandwich and Deal
The coast from Ramsgate to Kingsdown was covered by a separate alert.
The principal risk period was Monday morning, between approximately 8.30am and 12.30pm, when high tides and waves were expected to create an increased risk in exposed locations.
3. Whitstable, Herne Bay and Margate
The north-east Kent coastline between Whitstable and Margate was included in the Environment Agency’s alerts.
Exposed promenades, beaches, coastal roads and footpaths were among the locations where flooding was possible.
4. Isle of Sheppey, Sittingbourne and Faversham
A further alert covered the Isle of Sheppey and the coast between Kemsley and Seasalter.
The alert included low-lying coastal locations around the Swale, with residents urged to exercise care around high tides and potentially flooded routes.
5. Medway Estuary and Isle of Grain
Areas around the tidal Medway, its estuary and the Isle of Grain were also placed under a flood alert.
The Environment Agency warned that flooding was possible between 9.30pm on Sunday and 1.30am on Monday.
The alert covered locations including Aylesford, the Medway towns, Lower Halstow, Middle Stoke and Lower Stoke.
6. Dartford, Gravesend and North Kent Marshes
The final alert covered the coast from Dartford to Allhallows, including exposed stretches of the North Kent shoreline.
Coastal roads, marshland routes, footpaths and areas close to the Thames estuary were among the places where residents and visitors were urged to take extra care.
High Tides and Large Waves Create Coastal Flooding Risk
The flood alerts followed a period of stormy weather which brought powerful winds and widespread disruption to southern England.
Although the strongest winds had already caused problems across the region, coastal conditions remained a concern as high tides combined with large waves.
Water can overtop sea walls during rough conditions, even where permanent flood defences are in place.
This can make exposed seafronts dangerous for pedestrians and motorists.
The risk may be particularly significant on promenades, coastal roads and beaches where waves can arrive suddenly and with considerable force.
What Is the Difference Between a Flood Alert and a Flood Warning?
The Environment Agency uses different alert levels to explain the likelihood and potential severity of flooding.
A flood alert means flooding is possible and people should prepare and remain aware of changing conditions.
A flood warning means flooding is expected and people should take immediate action to protect themselves and their property.
The six Kent notices issued on Sunday were flood alerts, not flood warnings.
This distinction is important because the alerts do not mean that all the locations identified will necessarily experience flooding.
However, they should still be taken seriously, particularly where members of the public may be exposed to dangerous waves or rapidly changing coastal conditions.
Drivers and Coastal Visitors Urged to Take Care
People travelling along the Kent coast during the affected tidal periods were advised to avoid unnecessary risks.
The Environment Agency encouraged residents to stay away from coastal roads, footpaths and car parks where flooding could occur.
Motorists should not attempt to drive through floodwater, even where the depth appears manageable.
People walking near sea walls, harbours and promenades should avoid approaching the water to photograph large waves.
Powerful waves can overtop sea defences unexpectedly and sweep people from exposed surfaces.
Parents and carers are also advised to keep children away from dangerous coastal areas during periods of rough weather.
Further Flooding Possible Around Monday Morning High Tide
While several alerts focused on overnight conditions, the Environment Agency also highlighted Monday morning as a period of concern, particularly along the east Kent coast.
People in Ramsgate, Sandwich and Deal were warned of possible coastal flooding between approximately 8.30am and 12.30pm.
Other locations could also experience changing conditions according to local tides and wave exposure.
The Environment Agency continues to monitor river and sea conditions and may amend or remove alerts as the situation develops.
How to Check the Latest Kent Flood Alerts
Residents can obtain current flood information directly from the Environment Agency’s official service.

Kent Residents Urged to Stay Safe
The six coastal alerts demonstrated the continued risk posed by high tides and rough seas following a weekend of severe weather.
Although the notices were precautionary and did not mean widespread flooding was inevitable, people in exposed locations were urged to avoid complacency.
Anyone travelling along the coast should check the latest warnings before setting off and avoid areas where waves are breaking over sea walls.
UKNIP will continue to report any significant changes to flood alerts affecting Kent as the Environment Agency updates its information.
