SEVERE WEATHER WARNING.

Heavy rain for many parts of New Zealand. Cyclone Cook expected to bring severe gales to parts of the North Island.
A low lies slow moving west of the South Island directing a moist and unsettled northeasterly airstream over New Zealand. Heavy rain is now falling over parts of the country and is expected to continue into Thursday or even Friday in some regions. Rainfall accumulations could exceed 200mm over Bay of Plenty and Taupo during this time, with lesser amounts in other areas.

Cyclone Cook is expected to make landfall somewhere over the Coromandel Peninsula or western Bay of Plenty late Thursday afternoon or evening and move southwards reaching Wellington in the early hours of Friday morning. On this track, damaging severe gales with gusts of 150 km/h or more are possible, affecting regions from Auckland to Coromandel Peninsula and Bay of Plenty, down through the central North Island and into Wellington. Eastern coastal areas of Auckland, Coromandel Peninsula and Bay of Plenty may see large waves of 5 metres or more, storm surges near the centre of Cyclone Cook, coastal inundation and erosion. The precise track of the Cyclone centre may change as the system approaches.

People should be aware that this is a very significant event and is likely to produce widespread flooding, slips and wind damage, including to powerlines and may even lift roofs. Driving conditions are likely to be hazardous, so people will need to take extra care on the roads, and even consider altering their Easter travel plans.
