Rising river levels overnight may have led to flooding, but river levels are now falling again.

Locations most affected will be low lying land and roads near rivers.

We are closely monitoring the situation and checking river and rainfall levels.

Take care and avoid walking, cycling or driving through flood water. Avoid low lying roads near rivers, which may be flooded.

This message will be updated by 05:00PM on 09 January 2026 or as the situation changes.
