Flood Alert Issued for Groundwater Flooding in Villages Surrounding Andover

Alert Details

The Environment Agency has issued a flood alert for groundwater flooding in the villages surrounding Andover. This alert is managed by the Solent and South Downs area office and was raised on March 4, 2026, due to high groundwater levels in the region.

Affected Areas

The alert covers specific geographic regions within Hampshire and Wiltshire. Impacted locations include:

• Appleshaw, Hatherden, and Penton Grafton: Cellar flooding is currently expected to be occurring.
• Appleshaw and Penton Mewsey: Ongoing impacts to the sewerage system.
• Penton Grafton: The main road into the village is currently flooded.
• Kimpton: Water is emerging into Deacon and Down Road.
• Thruxton: Potential for surface water flooding if heavy rain returns later this month.

What You Should Do

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

• Prepare property resilience measures immediately.
• Ensure that all basement or cellar pumps are in good working order.
• Remove any valuables stored in cellars to prevent water damage.
• Monitor local conditions and road closures before traveling.

Expected Conditions

While only 14mm of rain has fallen in the last week, groundwater levels remain high enough to cause flooding. Current conditions include cellar flooding, sewerage system disruptions, and surface water on roadways. If further heavy rain affects the area during March, additional cellar flooding in Kimpton and surface water flooding in Thruxton could occur.

Timeline

The alert was issued at 3:39 PM on Wednesday, March 4, 2026. A mostly dry weather forecast is in place from Wednesday through Sunday, March 8, 2026, which should allow groundwater levels to begin to stabilize and slowly fall. The Environment Agency will provide an update on the situation by 6:00 PM on March 11, 2026, or sooner if conditions change.
