An unexploded World War Two bomb has been found in the Bristol Channel off Hinkley Point.
It is the third to be found there this month.
The coast was once used as part of a practice bombing range for the Royal Navy.
All vessels in the area are advised to proceed with caution. There is currently a 1,000m exclusion zone.
The 250 pound explosive is set to be examined and detonated later this afternoon, Wednesday 30 August.
