Drone pictures have revealed the extent of the latest erosion damage in Hemsby.
The pictures come after parts of the cliffs close to the lifeboat station fell into the sea overnight on Sunday.
Around five yards of the coast have been lost to the sea after high tides battered the seafront.
Hemsby Lifeboat coxswain Daniel Hurd said the lifeboat team are starting to pack up their headquarters in case of a sudden evacuation.
"I've got an awful feeling we won't survive the winter," said Mr Hurd.
"The lifeboat shed will be under threat soon. We're planning on starting to pack up the building soon, so we can be on standby if we have to leave.
"But we need to be close to the beach, so we can continue our service."
In a post on social media, the lifeboat station was calling for any cardboard boxes to be dropped at the headquarters to help with packing and transporting of equipment.
They also asked if there was anywhere they could temporarily store their equipment as they prepare to move over the next 12 to 18 months.
Beach Road has been home to the lifeboat station for more than 20 years and Mr Hurd is calling for the government to intervene to save more of the coast from falling into the sea.
He added: "It's getting worse.
"We need emergency powers to be called in to preserve what's left.
"I'm appalled the government can see what's happening, and still nothing is being done.
"We hope the station will be good until at least the summer.
"But who really knows?"
People are being told to avoid the area.
