Heavy rain - and snow - are on their way for the South later today, forecasters say.
Otago is due to get another drenching later today as a storm system moves over the lower South Island.
The MetService says rainfall may reach "warning amounts" in coastal and North Otago, and in Southland and southern Canterbury.
Rain will set in tonight in Dunedin and North Otago with 80 to 120mm of rain expected in some areas between midnight and midnight on Monday.
The heaviest falls are expected about the coastal hills and ranges of North Otago with rainfall of 10 to 15mm per hour likely tomorrow afternoon.
"These rainfalls are likely to lead to swollen rivers, and surface flooding. The effects will be exacerbated by already saturated ground from recent rains.
"People in all these areas engaged in weather sensitive activties should be aware of heavy rain coming."
The rain will be followed by a low with a strong southeast flow.
This will bring the chance of "substantial snowfalls" tonight and tomorrow down to about 900 metres in parts of Otago, Fiordland and inland Southland.
