Flooding possible. Be prepared.
High river levels over the next two days may lead to flooding.
Flooding is possible from the early hours of 31 January 2026 as more rain is forecast (15mm).
River levels remain high and may rise again. There may still be residual impacts to land, fields, and roads at Cadnam, West Wellow, Landford and Ower. Water levels will also still be high around, and affect the mill building at East Wellow. Further persistent rain is forecast today (30/01/2026) and Saturday (31/01/2026). This will cause the river to rise again, but it should not be as high as Tuesday (27/01/2026). Further impacts are possible from 02:00 31/01/2026.
We are monitoring rainfall and river levels and will ensure the river is kept free of reported blockages.
Consider activating any flood protection products you may have . Including pumps.
This message will be updated by 2:00PM on 31 January 2026 or as the situation changes.
