Snow could fall as low as 300m in Dunedin this evening as another cold blast makes it way north.
However, while the MetService has road snowfall warnings in place for roads across the South it is not expecting significant amounts to fall.
An earlier road snowfall warning for Dunedin's Northern Motorway this evening has been lifted, as MetService no longer believed snow was going to affect the road.
In Dunedin northwesterlies are expected to turn southerly about midday, with snow possible in the evening.
Elsewhere in the South a heavy rain warning is in place until 12pm today for Fiordland north of Doubtful Sound.
In the 12 hours to noon between 70mm and 100mm of rain was expected to fall and surface flooding and slips were possible.
