“We also have quite an active front moving onto the south of the South Island later in the day.”
In the North Island, Auckland, Northland, the Bay of Plenty, the Waikato and down to Taranaki will be wet from the afternoon, Baillie said.
“Central and eastern areas start pretty fine, but they will cloud over later in the day.”
On Friday, Baillie said it would be wet across most of the country when the two weather systems converge.
A heavy rain watch is forecast to come into force for the Coromandel Peninsula from 6pm, lasting for 12 hours.
Another heavy rain watch is forecast to last from 10pm until 10am tomorrow for the Bay of Plenty, west of Kawerau.
In the South Island, a heavy rain watch is set to begin from 9pm and last until 5am.
Baillie said strong easterly winds were still forecast for the upper North Island today.
“It will be a complicated situation during the next few days. Showers for most places, especially on Friday for the upper North Island and the west of the South Island.”
