Updated 9:15am — More heavy rain for some parts of the North Island today while patchy rain also expands over the upper half of the South Island. The storm in the Tasman Sea remains well away from New Zealand after bringing significant flooding to Hobart, Tasmania, on Friday night. Now the storm is tracking further up the Australian coastline and will drift out into the middle Tasman Sea over the next day or so, before falling apart over New Zealand on Wednesday.
The rain today in New Zealand is actually between this Tasman Sea low and the outgoing high.
After a short break from the wet weather on Saturday in northern New Zealand another frontal system will pass through the entire North Island from this morning and is now tracking into the eastern side of the North Island from the west – and is clearing from the west, including Auckland and Northland where drizzle is most likely.
Localised heavy rainfall of around 30mm/h is possible in north eastern parts of the North Island.
Temperatures will again be higher than usual in the North Island and western South Island (until Monday), due to mild sub-tropical northerly winds. This mild and humid flow is helping to destabilize the air and increases the risk of heavy downpours.
In contrast the eastern South Island, especially around Christchurch and coastal Canterbury, will again be cooler than usual today.
