The Environment Agency has issued a flood alert for Hambledon, Hampshire, as high groundwater levels cause cellar flooding and road closures.

Alert Details

The Environment Agency has issued a Flood Alert (Severity Level 3) for groundwater flooding in Hambledon. The alert was officially raised on February 26, 2026, at 2:38 PM following reports of high groundwater levels in the Solent and South Downs area.

Affected Areas

The alert specifically impacts the village of Hambledon in Hampshire. Currently, Fareham Road is closed due to flooding, and water is flowing onto the north side of East Street. Residents in the area are reporting widespread cellar flooding and issues with overflowing manholes caused by groundwater infiltrating the local sewer system.

What You Should Do

Residents in the affected area are advised to prepare property resilience measures immediately. If you have a pump installed to manage water levels, ensure it is in working order. The Environment Agency is closely monitoring the situation and is in active communication with the Hambledon Flood Action Group.

Expected Conditions

Groundwater levels in Hambledon are currently stable but remain high. Although only 9mm of rain has fallen in the last week, the existing groundwater is causing significant infiltration into infrastructure.

Timeline

The alert is effective immediately. Groundwater levels are expected to begin a slow decline during the weekend of February 28. Flooding impacts are projected to decrease gradually over the next week.
