Environment Agency advice issued
Groundwater levels in the Cranborne Chase area have begun to plateau, but remain over the flood alert thresholds. Flooding of fields and roads is still possible. Areas most at risk include the Iwerne and the Pimperne Brook areas. The start of this week sees brighter and drier weather, but further rainfall is forecast from Thursday, which could see levels rise again. 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 w
