The endless parade of storms across Europe this winter have left flooding, damage and even a few deaths, but along the British coastline, another danger has been discovered.

Unexploded bombs have emerged from beneath beaches in southwestern England and western Wales, according to a Daily Mail report. A highly active winter season of heavy surf and damaging winds from storm systems battering the coast led to erosion which brought World War II bombs out of the sand.

The report also states that officials are worried the River Thames may see similar erosion that could expose more unexploded bombs dropped by the Luftwaffe in the early 1940s.

A Plymouth Herald report says six resurfaced bombs have been defused in the last six weeks along British beaches, and officials have warned citizens to stay away from any additional bombs they discover and call police immediately.
