UPDATED 7:51am Monday — A huge area of low pressure is forming in the Southern Ocean creating a large storm which will span thousands of kilometres in diameter and brush New Zealand and south eastern Australia. It will affect our weather for about seven full days.
The storm itself won’t directly cross NZ, but it’s so large in size it can’t help but swipe us.
It means pockets of severe weather, potentially in both islands for a time, but while this is definitely one of the larger storms we’ve seen this year it also doesn’t equal an especially rough time for many parts of New Zealand. In fact for some areas it may enhance the sunny and hot weather you’ve already been having lately.
Big doesn’t always mean bad as these large weather systems tend to have very large areas of calm or what most of us would consider “normal” weather. Of course, being in a ship in the Southern Ocean next week would be a terrifying ordeal with gigantic seas and hurricane force winds. But for New Zealand and Tasmania – we’re on the edges of it and because it’s so large we will have plenty of non-severe weather in the mix too.
Most impacted by rain will be the West Coast with significant totals there which could leads to slips, flooding and road closures. Some snow on the ranges too. Winds will be strongest in the east, but especially around the mountains and Cook Strait next week.
The low pressure will remain hugging NZ just to our south until Monday of next week and basically means a westerly flow will kick in with rain on the West Coast, winds through central and eastern areas and remaining warmer than normal in the east and north. This set up doesn’t mean severe weather for all – so keep up to date with MetService for more details on where the official weather warnings are.
