Another wintry blast to come

September 2, 2013

This week another active trough will spread a bitterly cold southerly change across the country accompanied by snow to very low levels and large wind chills.

“This dramatic southerly change will sweep northwards during Wednesday,covering much of New Zealand by day’s end,” commented MetService Media and Communications Meteorologist Daniel Corbett. “Snow is expected to fall to low levels about southern and eastern parts of the South Island and the lower North Island. At this stage, significant snow accumulations are expected to be limited to the ranges and higher level roads of both islands, including the central plateau and Rimutaka Hill Road. However, people about Southland, Clutha and Dunedin should expect snow to near sea level during Wednesday.”

This sharp cold wintry blast will be challenging for farmers in the midst of lambing, with the risk of snow down to low levels and extreme wind chills. Snow is likely to cause disruption to traffic, especially about the higher level roads of both islands.
