The Environment Agency has issued a Flood Warning (Severity Level 2) for groundwater flooding in the Piddle Valley within the Wessex area. The alert was officially raised on February 24, 2026, at 2:56 PM local time due to high groundwater levels that pose a risk to the surrounding region.

What You Should Do

Residents in the warning area are advised to take immediate precautions:

  • Prepare property resilience measures and ensure any installed pumps are switched on and working correctly.
  • Plan for alternative power sources in case of potential power cuts.
