High river levels are expected to cause flooding today. 

Flooding is expected on 18 December 2025 . 

River levels are rising again at the Great Somerford gauge from todays rain, and are expecting the River Avon to peak at 6am on the 19th December 2025 at a stage level of 1.8m. Flooding is possible. A further band of rain is expected on Sunday the 21st December with totals up to 20mm, therefore the risk of flooding remains over this weekend and Monday the 22nd December 2025. Flooding is forecast to affect locations near the Bristol Avon, with low lying land and roads expected to be most affected, particularly around properties at Reybridge and Seagry; the Kellaways. 

We are closely monitoring the situation . 

Take care and avoid walking, cycling or driving through flood water . 

This message will be updated by 3:13PM on 18 December 2025 or as the situation changes.
