An Antarctic polar blast swept across parts of New Zealand's South Island on Tuesday (August 4), bringing snow to sea level and icy temperatures that forced road closures and disrupted schools.

Snow blanketed Dunedin, the South Island's second-largest city, prompting police to urge residents to avoid travel unless absolutely necessary because of icy roads.

Snowfall is uncommon in Dunedin, particularly at sea level, although the city's hill suburbs can receive snow during severe cold outbreaks.

All bus services in the city were cancelled, authorities said, while ferry services between New Zealand's North and South islands were suspended because of strong winds and heavy swells.
