NEW FEATURE: Through our new official partnership with IBM/The Weather Company we’re proud to bring you a new frequent service. Better maps and bullet point updates on the main weather news headlines.

On top of the InfoGraphics we already create at WeatherWatch.co.nz, we’re now going to frequently include these graphics covering New Zealand and Australia.

Please note, this blast of spring weather brings the chance of thunderstorms, localised heavy rain and localised damaging wind gusts. 

UNSETTLED SUNDAY/MONDAY

The main weather features…

• A developing low, which is connected to a system in the Southern Ocean, will move off the west coast of the South Island on Sunday and into the North Island.
• Localised heavy rainfall for those in the North Island.
• Thunderstorms, mainly over the Tasman Sea to the west of the North Island will push into western and central parts of the North Island (in first two maps below in red).
• Rain will affect much of the North Island for a time, especially western and northern areas – and the northern-most part of South Island from Tasman to Marlborough.
• Short-duration heavy rainfalls of 10-30mm/h are expected in Auckland on Sunday morning, and in Bay of Plenty to Hawke’s Bay on Sunday early afternoon. 
• Thunderstorms and wind gusts will occur as upper level cold air provides conditionally unstable air.
• Strong gales will persist in some exposed areas of the North Island from Sunday afternoon to Monday morning.
• Canterbury mostly settled and sheltered from this

Yellow = 22 to 32 km/h
Gold = 32 to 43 km/h
Orange = 43 to 61 km/h (gale force begins after 61km/h).
No Colour = Light winds

Please note – this is for SUSTAINED winds, gusts will be higher and the geography may produce isolated briefly damaging wind gusts over 100km/h.
