Environment Agency advice issued
There is no longer a threat of flooding, though standing water and debris may still remain. Coastal conditions are expected to improve and no flooding is expected. We will continue to monitor the situation and will issue further alerts or warnings if necessary. Continue to take care on waterside roads and footpaths and don't put yourself in unnecessary danger. Stay away from floodwater - it contains hidden dangers such as open manhole covers, sewage and chemicals.
