La Nina’s last assault?

If you’re unhappy with the current weather then we have bad news for you – the forecast for the next 10 days looks fairly similar.

The weather patterns have locked into a new position for at least the next week and a half predicts which will see plenty of easterlies, clouds and rain over the North Island but fairly dry, sunny, weather over the South island.

Long range models also indicate low after low forming in the north Tasman Sea and Coral Sea areas with high pressure to our east and south making the upper North Island vulnerable to heavy rain events.

The set up over the next 10 days also puts Taranaki and other central western areas of the country in the squash zone between low and high pressure – in other words, where the isobars will bunch up bringing strong winds at times from the easterly quarter. says after today’s downpour another weaker low could bring in further wind, rain, showers and cloud for the rest of the week, while another more aggressive sub-tropical low is expected this coming weekend/early next.

The South Island should be mainly dry under a ridge of high pressure this week but heavy rain in the west and strong northerly winds in the east are likely to arrive next week.

Despite a brief cold snap heading up the South Island over the past 24 hours believes most places across New Zealand will have temperatures above average, particularly at night, over the coming week or so.

NIWA says La Nina is now starting to weaken as we head into winter but it is still fairly active.
