Federated Farmers expects few problems from bad weather across the lower South Island.
MetService is forecasting snow lowering to about 200 metres on Sunday afternoon.
It says the heaviest falls should be above 300-metres about Southland, Fiordland, Cutha and Dunedin, where up to 10cm may accumulate.
A storm in Southland in late September caused more than $50 million in stock and production losses on farms.
But Federated Farmers says the storm coming through now is minor in comparison.
Southland meat and fibre chair Andrew Morrison says most farmers are now through lambing and those in the hills who are just starting, are well prepared.
