A map has shown where residents face possible flooding around the Watford area today as the town recovers from torrential rain overnight.

The Environment Agency has put flood alerts in place for the rivers Gade and Bulbourne, meaning flooding is possible today in low lying land in Croxley Green, Hunton Bridge and Kings Langley, as well as Boxmoor and Hemel Hempstead.

It is the least serious rank in the warning system, below “flood warning” which means it is expected or “severe flood warning”, meaning it could be a risk to life with significant disruption to communities.
