Cyclone Pam - the story so far
Cyclone Pam - the story so far
Tropical Cyclone Pam
moved into MetService's Tropical Cyclone Warning Centre area
of responsibility in the early hours of Sunday morning. At
that time, the predicted track would take the cyclone on a
southeast course past East Cape, with warnings and watches
issued by MetService for heavy rain, severe gales and heavy
swells for the northern and eastern parts of the North
Island.
The rain bands started to spread over the North Island on Sunday afternoon with winds strengthening along the eastern shores of Northland, through the Hauraki Gulf, Coromandel and Bay of Plenty. By Sunday night, the wind was observed to gust to 150 km/h near Kaeo in Northland and 144 km/h at Channel Island between Coromandel Peninsula and Great Barrier Island. Steady rain continued to fall in the area, with 51mm recorded at Whangarei Airport and 49mm at Whitianga Airport in the 24 hours to 7am this morning.
The cyclone was re-classified as an intense extra tropical cyclone at 1:15 amthis morning, as it continued along its forecast trajectory, with the centre lying 230km east of East Cape at 1pm. Despite being re-classified, this system still has the power to bring the severe weather which is affecting parts of New Zealand. Heavy rainfall continues to fall in the ranges of Gisborne, with accumulations at several stations now in excess of 150mm in the 24 hours to 2pm today, and wind gusts reaching 145km/h at Hicks Bay. Maximum wave heights of 4 metres have been measured at Eastland Port in Gisborne, and these are expected to rise to 5-6 metres this afternoon.
Cyclone Pam has been a significant coastal event for the east coast between North Cape and East Cape. Surfers in those areas will be pleased to hear that as the large seas gradually ease over the next 24 hours, the wind stays offshore (southwesterly) and the swells will clean up nicely over the next 2 days. Cyclone Pam is moving southeast and is expected to maintain its intensity, or may even intensify slightly, reaching the Chatham Islands around midday Tuesday. A warning is now in place for severe gales, heavy rain and heavy swells for the Chathams.
