SPRING WESTERLIES THIS WEEK

September 12, 2011

A strong cold west to southwest flow is expected to dominate New Zealand’s weather over the next few days.

“This is a typical spring weather pattern,” commented MetService Weather Ambassador Bob McDavitt. “For much of the North Island, and for the west and south of the South Island, it’s likely to be noticeably windy this week. The strongest winds will occur in episodes, which MetService will highlight in Severe Weather Watches or Warnings.”

McDavitt added that these southwesterlies are expected to bring cold conditions to Southland and Otago over the next couple of days, with snow down to a few hundred metres above sea level from Monday night through to the middle of Tuesday. “North Canterbury is also likely to see snow on Tuesday morning” commented McDavitt. “Again, keep an eye on the Severe Weather Watches or Warnings.”

Snow may affect the South Island’s higher roads until Tuesday afternoon,and then sweep across the Desert Road from Tuesday evening. The combination of wet weather and strong winds may prove stressful to new-born livestock.
