SAINTS Harbour may have been dangerously destabilised following the weekend’s storms.
And waves have also knocked a hole through the Fermain sea wall, resulting in the tide pulling huge amounts of earth into the bay.
Portelet slipway and Cobo were also found to be damaged as the full impact of the severe weather became clear yesterday.
A hole in the Perelle slipway has been mended, but sea defences on the east coast at La Miellette and on the north-west coast at Pulias Pond still need attention.
States Works has been clearing the western coast road, while engineers and stonemasons have been inspecting the damage caused by strong winds and high tides.
It is unclear how much it will cost to repair the damage.
A telephone cable to Jersey and France – which is normally encased in concrete beneath the Saints Bay slipway – has been exposed, after pounding waves ripped up half the granite walkway.
