Coastal flooding and the rare super tides                 

Rare super tides, which only occur once every 18 years, are threatening coastal flooding in parts of England.

The phenomenon is caused by a unique alignment of the sun, moon and Earth creating a massive gravitational pull on the sea. The Environment Agency has issued a number of flood warnings and flood alerts across the country.

There's a risk of localised flooding around the Wye Estuary in Gloucestershire and Monmouthshire, along with parts of the Yorkshire coast and Morecambe Bay. Localised disruption to travel and some flooding of low-lying land and individual properties is possible. This might prove a test for flood defences recently put in place at Hest Bank, Morecambe as part of Newground Flood Team’s efforts to assist residents.

People should take care especially on coastal paths and promenades as high tides can sweep people off their feet.  As always with any type of flooding, don’t drive through flood water.

The situation is being monitored closely by the Environment Agency working alongside the Met Office and further flood updates or warnings may be issued if required.  If you are a property owner you should know your flood risk and keep up to date with the latest situation – FloodAlerts.com is a good place to visit.

A combination of low pressure and strong winds can also cause coastal flooding. This is exacerbated with certain alignments of the sun and moon with the Earth

The last super tide occurred on 10 March, 1997 and the next will take place in March 2033.
