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 work with emergency services and local authorities. Stay away from floodwater - it contains hidden dangers such as open manhole covers, sewage and chemicals.
