Portsmouth Warning no longer in force 3:13pm, Friday 7th November 2025

Warning no longer in force

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. As tides will remain high until Monday (10/11/25), coastal defence gates will remain closed throughout Old Portsmouth over the weekend.
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. Never drive through flood water, just 30cm of fast flowing water is enough to move your car.
