Environment Agency advice issued
Groundwater levels in the Salisbury Plain have remained risen in response to recent rainfall. Levels are expected to plateau this week, flooding of fields and roads is still possible. Levels are reactive to further rainfall. The start of this week sees brighter and drier weather, but further rainfall is forecast from Thursday, which could see levels continue to rise. Where groundwater is near the surface, intense rainfall will lead to surface water flooding. We are closely monitoring the situation. Residents are advised to prepare property resilience measures and ensure that pumps are working
