A storm that brought heavy rain and gusty winds to Auckland and Northland has moved further east – but more is on the way this afternoon.
MetService meteorologist Michael Martens said the front had moved over eastern Bay of Plenty this morning.
Heavy rain watches were in place for the Bay of Plenty and Gisborne north of Te Puia Springs this morning, and Nelson west of Motueka. There was also a risk of squally thunderstorms about Bay of Plenty.
Last night‘s storm brought less rain than forecast, with an average of 10-20mm recorded across Northland, Auckland, Coromandel and Waikato, Martens said.
There was still a moderate risk of thunderstorms over southern Northland, northern and eastern Auckland, including Great Barrier Island, and the north of the Coromandel Peninsula before dawn, and about the south of the Coromandel Peninsula and the Bay of Plenty in the morning.
Impacts: Wind gusts this strong may cause scattered power outages along with downed branches and trees.
Secure any loose items in your yard or bring them indoors!
In addition, coastal inundation is possible for the western coasts of Auckland and Northland. (High tide ~10 pm).

These thunderstorms were likely to produce localised heavy rain of 10 to 25mm per hour and there was also a slight risk of a small tornado near the coast.
A Fire and Emergency spokeswoman this morning said there were no weather-related callouts in the northern region last night.
The weather would ease for a time about the upper western North Island this morning, before a southwesterly change brought heavy showers and strong winds from mid-morning.
There was also a moderate risk of thunderstorms developing about the west coast of the North Island from the west of Auckland to North Taranaki late morning ahead of an approaching front over the Tasman Sea.
These thunderstorms were likely to produce localised heavy rain of five to 15mm per hour and small hail.
Auckland, including Great Barrier Island, Coromandel Peninsula, Waikato and Bay Of Plenty west of Te Puke were under a strong wind watch from 4pm to 1am Wednesday.

Martens said these winds could approach 100km/h.
Winds would ease by late evening, with showers persisting.
The rest of the country was not looking too bad today, Martens said.
“South of the Central Plateau winds and rain will be lighter. There will be periods of rain across the South Island, but it will gradually clear.”
After a month of relatively quiet weather, Auckland is in for a busy 48 hours! We‘re in for King Tides, a couple of decent bursts of rain, and risk of severe gales on Tuesday evening. More at ^GG

Tomorrow a weak ridge would spread over the country ahead of a front arriving tomorrow night, bringing heavy rain to the West Coast and light falls in the east.
The front would spread on to the North Island late Thursday followed by a showery Friday across most of the country along with some colder air.
“Not unseasonably cold, but back to average,” Martens said.
The snow level would lower to about 1000m across the South Island.
Another weak ridge would form early Saturday bringing some respite in the North Island, before another front arrived in the South Island.
“Overall the weekend is not looking too good, except in the North Island on Saturday,” Martens said.
“But there will be more rain in both islands on Sunday.”
