The Environment Agency have issued flood alerts for villages in the Bourne Valley area at 6.57pm on Wednesday 19th February.
Communities at risk of groundwater flooding in Vernham Deane, Upton and the Bourne Valley in North Hampshire including Hurstbourne Tarrant and St Mary Bourne.
Groundwater levels in the Bourne Valley have continued to rise in the last week. Levels are now higher than 2000/01 when there was internal flooding in Vernham Dean & Upton.
The forecast is for conditions to remain unsettled. Over the coming days 15–25mm of rain is expected. Any significant rainfall will run off more rapidly than usual into flooded areas as a result of the saturated conditions.
Groundwater levels in the area are expected to remain high over the next week and problems associated with high groundwater levels will persist for many weeks. A Flood Warning has been issued for the Bourne Rivulet.
Groundwater levels are maintaining high base flows within the Bourne Rivulet and any additional rainfall will only compound the current flooding situation. Residents should prepare for levels to rise further this week.
Properties at risk of flooding are in the villages of St Mary Bourne Stoke, Hurstbourne Tarrant, Upton and Vernham Deane.
