Flood Warning Issued for North Winterborne Groundwater Levels in Dorset

Alert Details

The Environment Agency has issued a Flood Warning (Severity Level 2) for groundwater flooding in the North Winterborne area, south of the A354. This alert, managed by the Wessex office, indicates that high groundwater levels are expected to cause flooding in the region.

Affected Areas

The warning specifically covers geographic regions within Dorset Council, including:

• Winterbourne Whitechurch
• Winterbourne Kingston
• Winterbourne Zelston

What You Should Do

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

• Prepare and deploy property resilience measures immediately.
• Ensure that all installed water pumps are switched on and functioning correctly.
• Consider alternative power sources in the event of power cuts.
• Be aware of potential inundation of septic tanks.
