A sub-tropical low is today expected to develop in the northern Tasman Sea creating a fairly impressive looking depression north west of New Zealand over the weekend.

The low is in the prime position to bring much needed heavy rain to dry farms and water tanks across northern New Zealand, but, will it reach us.

Weather analyst Philip Duncan says the low is certainly going to ‘tease’ the country for the next few days.  “This low will be frustratingly close to Northland but I’m not yet confident it will bring solid rain.  Because there will be a blocking high to the east the low may not get the chance to cross northern New Zealand before it eventually weakens and falls apart”.

“If the high moves a little quicker away to the east then, yes, there is a chance heavy rain could spread down from the north on Sunday or Monday”.

Mr Duncan says it will be one to watch closely over the next two days.  “We will have all the feelings of a storm brewing, with brooding skies, strong nor’easterlies and the odd spit of rain, but we need to wait another day or so before being certain about just how much rain will fall”.
