How much rain will you get this weekend? The latest rainfall estimates (+4 Maps)


The low this weekend north west of New Zealand is large but weak and it's tapping into moisture rich sub-tropical air. A blocking high pressure system to the east of the country is slowing down these rain bands.

Here's the latest outlook by our meteorologists at the Weather Company showing forecast rainfall accumulations in 12 hour segments for New Zealand.

One positive is that for drought affected regions of the lower North Island there looks like some relief will be coming.

Rain will be patchy with drizzle, dry spells and heavy set in downpours across several regions until Monday or even Tuesday.

Highlights:

  • Rain accumulation for 12 hours may exceed 50mm in some areas. 
  • As the front moves southeastward, the area of heavy showers will follow. Tonight and tomorrow daytime the  heaviest rainfall is expected in the Tasman and western part of the North Island.
  • Temporarily heavy rainfall and isolated thunderstorms could also occur especially over interior regions in the North Island and in the vicinity of the front.  
  • Localised flooding is possible.
  • Drizzle and dry spells will also be in the mix.
  • Humidity will hit 100% at times with low cloud and even fog/mist.
