A Flood Alert has been issued by the Environment Agency for the east coast of Dorset.
Flooding is possible for Sandbanks, Poole Harbour, Bournemouth Beach, Hengistbury Head and Christchurch Harbour.
Tides are expected to be higher than usual due to the windy weather conditions tonight and tomorrow, with force 7 south-westerly winds and large waves.
High tide levels are between 8pm and 11pm, and again tomorrow from 8am.
The agency says: “Please be careful along beaches, promenades, coastal footpaths and roads as large waves and sea spray could be dangerous.
“People in the areas should consider taking action now. We urge all people to take care and not drive through flood water.”
