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.

A large but fairly weak sub-tropical low will drag down more humid northerlies this weekend and areas of rain - some slow moving heavy falls are in the mix but so too are drizzle patches and dry spells.

The low isn’t very strong so the rain bands will weaken in some areas due to the mountains and ranges getting in the way.

A low just north west of New Zealand is slowly moving southward, bringing locally heavy rain to the country this weekend.

Northern parts of the North Island will be under the influence of the low pressure system for a number of days and rain accumulation will continue and increase through this weekend.

High pressure dominates a large chunk of New Zealand but a weak low over the next few days will help to drive in narrow areas of rain, some heavy falls and some drizzly.

As many of you have been seeing for a number of days now in long range models a tropical cyclone is expected to form in the next day or so in the Fiji / Tonga area. According to reliable computer modelling the storm will intensify as it drifts westwards and may become 'severe' in the tropics - then starts to curve southwards by next Friday/Saturday (+/- a day).
