Flooding is affecting low lying land and roads close to the River Mimram, due to persistent rainfall in December and January, leading to high groundwater levels. Flooding is currently affecting the Fulling Mill Lane, Singlers Marsh, and Codicote Road areas in Welwyn. No property flooding is expected at this time. River levels in other areas remain below levels of concern. There are some showers forecast for Friday 31/01/25 but no further significant rainfall is forecast for the next 5 days. Avoid using low lying footpaths and any bridges near local watercourses and do not attempt to walk or drive through flood water. We are continuing to monitor the situation. This message will be updated by 5pm on Friday 31/01/25, or as the situation changes.
