Severe Tropical Cyclone Atu is being monitored by the Fiji Meteorological Service as it moves slowly southwards away from Vanuatu.  As of Tuesday morning, MetService expects the winds in the upper atmosphere to steer Atu off to the southeast late on Wednesday and during Thursday.  Responsibility for marine warnings on Atu will pass to MetService on Tuesday night or Wednesday morning.

“The strong winds and heavy rain associated with this system should remain well offshore to the east of the North Island,” commented MetService Weather Ambassador Bob McDavitt.  “So while Atu poses a threat to vessels on the high seas within a few hundred kilometres of its centre, it is expected to be a non-event  as  far as the New Zealand landmass is concerned.”

However, McDavitt added that a long and possibly heavy northeast swell is expected on eastern coasts from Northland to Bay of Plenty on Thursday.

“This long ground swell should start picking up on Wednesday afternoon.  On Thursday, combined with offshore wind the waves are likely to be smooth and clean, with most surf breaks going off.  However, having come from a tropical cyclone these waves need to be treated with respect.  We’re also just past full moon, so the tides are strong.”
