Alert Details

The Environment Agency has issued a Flood Alert (Severity Level 3) for groundwater flooding in Denton. This alert was officially raised at 5:07 PM on March 2, 2026, due to high groundwater levels in the Solent and South Downs area.

Affected Areas

The primary area affected is Denton in East Sussex. Specific locations at risk include local fields, the recreation ground, and a small number of cellars. Residents using Denton Road should be aware of potential flooding on the carriageway.

What You Should Do

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

  • Ensure that any basement or cellar pumps are in good working order.
  • Exercise caution when traveling on local roads, particularly Denton Road, which is prone to flooding.
  • Monitor local conditions as springs continue to appear.

Expected Conditions

Groundwater levels at the Houndean Bottom borehole are currently high and close to the surface. While levels are rising slowly, the forecast indicates only small amounts of rain over the next five days. High pressure and settled conditions are expected to persist through the first half of March 2026, which should eventually allow groundwater levels to fall.
