Minimal risk of severe weather over New Zealand this week

A low west of the North Island drifts northwards during the weekend and weakens, while a large ridge of high pressure spreads across the country. The ridge moves off to the east late Monday as an active trough approaches the South Island from the Tasman Sea.

A combination of afternoon heating and wind convergences are likely to produce showers over some inland parts of both islands over the period, with possible thunderstorms and localised heavy rain, however no widespread severe weather is expected.


Low confidence:
A 20% likelihood (or 1 chance in 5) that the event will actually happen.

Moderate confidence:
A 40% likelihood (or 2 chances in 5) that the event will actually happen.

High confidence:
A 60% likelihood (or 3 chances in 5) that the event will actually happen.
