On Wednesday, bitterly cold Antarctic air will begin to sweep up the country. This has the potential to bring significant snow to the south and east of the South Island, as well as central and southern parts of the North Island. Largest snowfalls at this stage seem likely about inland Canterbury and Marlborough, while snow may fall to near sea level from Southland to Kaikoura by Thursday.
This is a very dynamic weather situation, and details about where the snow will fall and how much may well change. It will be important to keep up to date with the latest watches and warnings.

People should be aware that snowfalls are likely to cause widespread disruption to traffic especially about alpine passes and higher level roads, and more generally in Marlborough, Canterbury, Southland and around Dunedin. Exposed parts of the South Island east coast are likely to experience blizzard conditions for a time during Thursday and Friday, which will put stress on livestock and make outdoor pursuits hazardous. A severe weather watch is currently in force for heavy snow about southern and eastern parts of the South Island and severe gales about central areas. People are advised to stay up to date with the latest forecast and warnings.
