The Environment Agency has issued a Flood Warning (Severity Level 2) for groundwater flooding in the North Winterborne area, north of the A354. This alert was officially raised by the Wessex regional office on March 9, 2026, at 9:33 AM.

What You Should Do

Residents in the affected areas are advised to take the following precautions:

• If you have a pump, ensure it is functional and switched on.
