A “significant” shift in the weather patterns this week means northern New Zealand is in for some decent rain fall over the next few days, with a number of rain warnings being issued by our Government forecaster.
“We’ve been hearing all this talk of La Nina lately, but with plenty of high pressure over northern New Zealand we haven’t really seen any true evidence. This week we have a text book La Nina set up with wet, humid conditions to the north and a large high to the east” says head weather analyst Philip Duncan. “This shift in the patterns is a significant one and farmers across eastern parts of the North Island will be able to let out a sigh of relief with the forecast of several days of rain or showers ahead”.
Duncan says the shift in high pressure, from north of NZ to east of the country, does potentially open the flood gates to one low after another. “The last time we had a set up like this was back in Winter when we had several lows in the northern Tasman that brought heavy rains to Northland”.
And the weather certainly will be sub-tropical in the North Island. Auckland’s overnight low tonight is 18 degrees.
Meanwhile the South Island will enjoy plenty more sun later this week as a large high builds over the region. Yesterday Invercargill reached 26 degrees with a warm dry northerly.
