Flood alert

High river levels today may lead to flooding.

Flooding of property and roads is expected, especially in the Free Prae Road area. A Flood Warning is in force for areas of Chertsey closest to the Chertsey Bourne. Further rainfall is forecast over the next 24 hours. River levels are slowly falling but we expect levels to remain high and responsive to further rainfall over the next few days.

We are closely monitoring the situation. We are liaising with emergency services and local authorities.

Avoid low lying roads near rivers, which may be flooded. Stay away from flood water - it contains hidden dangers such as open man hole covers, sewage and chemicals.
