An intense burst of rain has occurred in the hills near Belgrove.
This has caused flooding to occur in the Wai-iti River, flowing between Belgrove and Wakefield.
Residents in the area may not have noticed this rainfall in the hills.
It is recommended that stock in the area are moved to high ground, if possible.
Please be aware that surface flooding may be present. Take extreme care when driving through this area.
