MetService meteorologist John Law said Auckland was in for an early morning drenching.
“It’s going to be one of those interesting situations as we wake up. Auckland could find it’s a wet start to the day. Everything is moving eastwards,” he said.
He told the Herald the last place to see the rain clear away today would be areas like the Bay of Plenty and Coromandel.
“As we head through Wednesday, we’ll find the weather starts to move away.
“For Northland, Auckland, the rain should start to clear off as we head in towards the afternoon. Perhaps even a bit of brightness or some sunshine back,” Law said.
He said tomorrow and into Friday was looking to be much better as the rain begins to clear away for most regions.
Law said MetService was keeping a close eye on the weather in the Bay of Plenty and the northern part of Gisborne/Tairāwhiti throughout today.
‘Intense bursts’ to continue for some
He said the northern parts of the country were expected to see downpours overnight that will continue for some this morning and into the afternoon.
“It’s not just the case that it’s wet, but there’s also that risk of some intense bursts of rainfall, some downpours.”
Earth Sciences New Zealand (formerly Niwa) forecaster Chester Lampkin earlier told the Herald an area of low pressure in the Tasman Sea and a cold front coming in from the southwest would bring a big plume of moisture from the Tasman.
“We call it an atmospheric river because of the amount of moisture coming with it,” he said.
