Snow is creating a little trouble on alpine routes around Canterbury and Otago as a cold front moves across the South Island.
The white stuff is expected to fall as low as 100 to 200 metres in Fiordland, Southland, Clutha and Dunedin today and may even reach as low as sea level along the southern coast.
Northern Westland and Buller could also get a taste of snow around 200 to 300 metres this afternoon, with heavy snow expected above 500 metres tonight and tomorrow.
Canterbury could see snow showers near the foothills this evening with a few flakes falling around 200 metres and heavier falls above 400 metres.
MetService has issued a severe weather watch but advises locals to keep up to date with the forecast in case it's upgraded to a warning.
Chains should be carried on many roads including Porter's Pass between Springfield and Arthur's Pass, Lewis Pass between Springs Junction and the Hamner turnoff, SH80 between Aoraki Mout Cook and Twizel and SH8 between Omarama and Tarras.
