Supertides that occur just once every 18 years threaten to flood parts of the UK, the Environment Agency has warned.
Tides are due to the gravitational pull exerted the sun by the moon and, to a lesser extent. A particular conjunction of earth, moon and sunlight that happens every 18 years causes an enormous gravitational pull on the ocean, and this results in bigger-than-ordinary spring tides, or ‘supertides’.
The Environment Agency encouraged the people to assess the threat for their local area and issued 44 alarms and 10 flooding warnings across the united states.
‘Localised disruption to travel and some flooding of low lying property and individual properties is possible,’ a spokesman said.
‘We urge visitors to take care near promenades and coastal routes rather than to drive through flood water.
‘ The Environment Agency is monitoring the situation carefully alongside the Met Office and certainly will issue warnings and additional flooding updates if needed.’
Parts of the Yorkshire coast and the place around the Wye estuary in Monmouthshire and Gloucestershire are particularly vulnerable to localised flooding, the spokesman added.
Yesterday, autos and vans drove through more than 2feet of water in Mersea Island, Essex following significant rain.
High tides don’t automatically cause flooding by themselves, if they coincide with a variety of strong winds and low pressure, but they can.
