Three severe flood warnings are in place following a tidal surge on the River Severn.
Some people took canoes and surfboards out to ride the Severn Bore, despite officials warning the public to stay away.
The BBC's Sophie Long was on the banks of the river and watched as the levels quickly began to rise.
