Cyclone Cook
Cyclone Cook has arrived in New Zealand coastal waters this morning and MetService is following its movement very
closely. Widespread rain continues over large parts of the country, although the heaviest and most significant falls
remain closely wrapped around the low centre. MetService’s rain radar indicates that this area contains very heavy
rainfall, which is expected to move onto Coromandel Peninsula and Bay of Plenty from this afternoon ahead of the low
centre this evening.
At the same time, damaging severe gales will accompany the low centre with wind gusts of 150km/h or more possible. In
addition, swell of five metres or more is expected with this event in the northeast of the North Island, before heading
to the south coast of the North Island tonight, and when you add this to the strong winds we can expect very high waves.
Sea conditions will be dangerous and large waves may lead to coastal inundation and erosion.
“Cyclone Cook is set to track southwards at a fast pace, bringing severe weather further south while clearing from the
north and leaving more settled weather in its wake,” said Meteorologist Arno Dyason, “The low centre is expected to sit
over the lower North Island late tonight or early Fridaymorning, then track just offshore down the east of the South
Island for the remainder of Friday.”
Most regions remain under a Severe Weather Watch or Warning during today and tomorrow as heavy rainfall and strong winds
are also expected further away from the centre of the cyclone.
“Cyclone Cook’s arrival in New Zealand is a very significant event due to the severity of the storm and people are
advised to take extreme care,” said Mr Dyason, “People should prepare for the possibility of flooding, landslips, wind
damage to powerlines, property and large trees. People should be prepared to change their travel plans if necessary as
driving could become hazardous during the severe weather period. “
