Flooding possible. Be prepared.
High groundwater levels may lead to flooding.
Flooding is possible from Tuesday 10/02/2026 due to a very wet beginning to 2026.
Flooding could affect a small number of cellars in Upton. Septic tanks will also struggle to operate properly. Light rain is forecast from today (07/02/2026) through to Wednesday (11/02/2026). Groundwater levels in the Bourne Valley are expected to rise for at least another week. At Vernham Dean, Hurstbourne Tarrant, Stoke and St Mary Bourne flooding impacts are not expected imminently, but could occur towards the end of February if further heavy rain affects the Bourne Valley.
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 especially if you are in Upton.
This message will be updated by 6:00PM on 13 February 2026 or as the situation changes.
