From The Environment Agency:

River levels have risen at the Hay-On-Wye river gauge as a result of heavy rainfall.

Consequently, flooding of roads and farmland is possible. We expect flooding to affect low lying land and roads along the River Wye from Hay on Wye to Ross on Wye. Other locations that may be affected include the A438, Byford, Bredwardine and Hereford. Predicted peaks:- Hay on Wye between 1.8 and 2.1m this evening, Bredwardine 3.4 to 3.7m this evening, Belmont 3.5 to 3.8m overnight and Old Wye Bridge 3 to 3.3m overnight We are closely monitoring the situation. Please avoid using low lying footpaths near local watercourses and plan driving routes to avoid low lying roads near rivers, which may be flooded. This message will be updated by 9am on Monday 05/10/20, or as the situation changes.Ā
