Alert Details
The Environment Agency has issued a Flood Alert for groundwater flooding in the Solent and South Downs area. The alert was raised on March 11, 2026, due to rising groundwater levels following recent rainfall.
Affected Areas
The primary areas affected include Deane and Ashe in North Hampshire. Specific impacts have been noted at the borehole in Oakley, and the River Test is currently flowing through Deane and Ashe. Residents in the county of Hampshire should remain vigilant.
What You Should Do
Residents in the warning area are advised to take the following precautions:
- Prepare property resilience measures immediately.
- Ensure that all installed pumps are in good working order and ready to reduce water levels.
- Monitor septic tanks, as high groundwater levels are currently affecting their ability to operate effectively.
- Prepare for potential cellar flooding, particularly in the Deane area.
Expected Conditions
Groundwater levels at the Oakley borehole have risen by 10cm over the last week following 10mm of recorded rainfall. Forecasters expect between 15mm and 20mm of additional rain to affect Hampshire from Thursday, March 12, 2026, into Friday, March 13, 2026. While Saturday and Sunday are expected to be mostly dry, any heavy rain during this period will likely trigger cellar flooding in Deane.
Timeline
