The island is bracing itself for more flooding with a storm surge at high tide this lunchtime.
Roads have been shut in preparation.

It is predicted that the east coast of the island will face the main impact of the storm surge, with strong to gale force southeasterly winds and low pressure resulting in large waves breaking over promenade walls and sea defences.
Douglas and Laxey are expected to be badly hit.
Road closures are in place at key locations across the island and the entire section of Douglas promenade between the Sefton Hotel and Port Jack is shut to traffic and pedestrians.
Pedestrian access along the landward pavements of Douglas promenade will be permitted as soon as it is considered safe to do so.
Motorists are asked to abide by all road closures, drive to the conditions and to plan their journeys – particularly late afternoon travel from the capital as Douglas promenade may still be closed to traffic.
It is possible that Castletown and Ramsey could experience inner harbour flooding on a similar scale to Saturday, although early indications point to water levels being slightly lower today.
Gansey, especially the area by the Potteries, Port St Mary and Peel may also be affected.
Householders and shop owners are encouraged to take steps to protect their properties and vehicles from the storms and flooding, and to help elderly or vulnerable members of the community wherever possible.
Officers from the Department of Infrastructure, the police, the fire service, the ambulance service, Civil Defence, coastguards and Water and Sewerage Authority are working together to try to mitigate potential damage.
In addition to the 20,000-plus sandbags deployed ahead of Saturday’s severe weather event, other contingency measures such as one-tonne bags and flood barriers will again be in position to help seal off roads in vulnerable areas.
Police asked people to keep clear of flood waters and breaking waves. Motorists should park vehicles away from promenades and harbours to avoid possible damage from flying debris and flood waters.
Road closure orders are in place between 10am and 6pm. Although roads can be closed from 10am, they will remain open until it is necessary to close them on safety grounds.
