Flooding possible. Be prepared.
Groundwater levels in the Bourne Valley are high and continue to slowly rise. In the last week, the level at Vernham Dean has risen by 68cm. In Upton, we expect a small number of properties to be experiencing cellar flooding. Septic tanks in the valley will be struggling to operate properly. From today (13/03/2025) to Monday (17/03/2025), only small amounts of rain are forecast. Groundwater levels at Vernham Dean will peak before the end of the weekend. We do not expect impacts to property at Vernham Dean, Hurstbourne Tarrant, Stoke or St Mary Bourne. In Upton, if you have pumps to help reduce water levels, please ensure they can operate. This Flood Alert will be updated by 18:00 on Thursday 20/03/2025.
