Scotland Yard's Marine Policing Unit has been reporting that a pod of dolphins has found its way up the Thames:
Marine 2 have been alerted to a sighting of a dolphin near Tower Bridge.
No further sightings of the #dolphin to report of. We're not sure if its here by accident or whether it swam here on porpoise......
Breaking #dolphin news.. Marine 2 are following a pod of about 5 harbour porpoises in the Lambeth area of the river.
Some parts of the UK are have seen the worst storm surge in 60 years, but we are not out of the danger yet.
A combination of factors are combining to make this storm surge particularly powerful.
Water levels around the UK could be higher than in the storm surge of 1953, but thanks to flood defences the impact is likely to be smaller.
