Explosives from World War II have appeared on beaches during the storms.
The devices have washed up in Devon, Somerset and Dorset because of powerful seas.
They include what is thought to be an illumination mortar, spotted by a passer-by on Crow Point beach in north Devon.
The Royal Navy worked on the device and declared it safe. ‘Ferocious seas and weather are thought to be responsible for uncovering or washing up these shells,’ Devon and Cornwall Police said.
The public must not touch any such devices, it warned.
