– That means strong winds for many
Highs to the north and deep lows to the south will place New Zealand squarely in the “Squeeze Zone” this week according to the Radio Network’s Head Weather Analyst Philip Duncan. He says when low air pressure pushes against high air pressure it creates strong winds. “And basically right in the middle of all this is New Zealand. So we’re going to get strong westerlies this week, especially up the west coast and strong nor’westers about Wellington off and on this week”.
Duncan says it’s like a giant motorway south of New Zealand with one low after another spiralling around Antarctica, while in the north slow moving anticyclones will drift eastwards off Australia. “As these lows fire up from Antarctica they slam into these highs…this creates strong winds over New Zealand and if conditions are warm enough in northern New Zealand thunderstorms and heavy showers also develop”.
The windy conditions are expected to last off and on for at least the next 7 days with only the far north seeing more settled conditions which also means those showers will taper off tomorrow from Waikato northwards.
