Change is in the air
New Zealand has been graced with generally settled weather over the past week, with most places getting several days of
sunshine. The exception was a front that made its way up the South Island to end the week, resulting in a temperature
drop of around 11C in just 10 minutes in Dunedin City, and similar temperature drops were experienced up the east coast
as the front moved north. An approaching low from the Tasman Sea means that change is in the air over the coming week.
“A low is currently forming across the Tasman Sea, and will head towards New Zealand this week,” said MetService
Meteorologist Claire Flynn. “The low is expected to stay to the northwest of the country. However, this draws a
northeasterly flow across the North Island, dragging humid air down from the subtropics, bringing rain.”
A front associated with the low is expected to move up the South Island on Tuesday, bringing a period of rain followed
by showers. Most of the South Island should see a return to settled weather after the front moves over on Tuesday, so
any rain should be short lived. Meanwhile, the humid northeasterly flow persists over the North Island for much of the
week, meaning rain in the north will last longer.
“There is still some uncertainty about which areas will get the heaviest and most persistent rain in the North Island,”
Flynn explained. “We are watching this low as it develops and approaches New Zealand, as it has the potential to bring
significant rainfall accumulations to parts of the North Island. Severe Weather Watches and Warnings are likely to be
issued closer to the time, so make sure you keep up to date.”
