Environment Agency advice issued
Groundwater levels in the West Dorset area have begun to slowly recede, but remain over the flood alert thresholds. Flooding of fields and roads is still possible. Groundwater levels remain responsive to further rainfall. 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 where they have been installed . This message will be updated by 11:00AM on 30th March 2026 or as the situation changes.
