A Tasman Sea low is likely to briefly reach storm criteria in the Tasman Sea this week before partially falling apart as it moves across New Zealand mid week.
WeatherWatch.co.nz says that at sea on Tuesday the low will likely have gale force winds wrapped around the centre of it – but as it interacts with New Zealand it will lose wind speed and start to weaken.
The low is expected to dump some heavy rain into parts of the country, however areas that need it most – like Auckland – may not see great rainfall totals compared to other areas further south. Still, the rain will again be helpful in our largest city which has had water restrictions in force since May.
This low matches what we said in our latest Climate/Monthly outlook for November…that La Nina would see an uptick in wet weather events for the country, but it may not be enough to help everyone.
For Wellington the run of cloudy weather continues with the cloud data in our Hourly forecasts at both WeatherWatch.co.nz and RuralWeather.co.nz showing overcast or mainly cloudy skies for a number of days this coming week. While this low may not bring gales at first to Wellington, it may leave a sting in its tail with a burst of strong to gale southerlies later this week and into the weekend.
This low is likely to trigger rainfall warnings across parts of both islands – and some wind warnings too, in the days ahead.
To make sense of this all for where you are locally, we suggest you look at www.RuralWeather.co.nz – with extra graphs and Detailed Daily Data. Also, the *hourly* forecasts at WeatherWatch.co.nz will also help make sense of rainfall totals and the windiest and wettest times coming up this week.
We’ll have more details in our Weather Video with Philip Duncan later on Monday morning.

La Nina usually brings in more rain for these regions, glad to see it’s happening (although Napier has definitely had too much of a good thing, not a positive when it’s delivered that fast and heavy).
