From NZ Metservice
ISSUED AT 9:15 am 10-Jun-2014
Heavy rain over northern and eastern parts of both islands for the next few days. Gales for northern New Zealand this evening (Tuesday).

A large complex trough lying slow moving to the west of New Zealand directs a moist northeast flow over northern and central parts of the country. A deep low embedded within this trough is expected to move south over the upper North Island overnight tonight (Tuesday to Wednesday), moving the rain-band slowly south over the North Island east coast during Wednesday.

Rain is expected to persist about the northern parts of the North Island and northeastern parts of the South Island today and part of Wednesday, before spreading over eastern parts of the North Island during Wednesday and Thursday. The heaviest falls are expected about Northland, Auckland, Coromandel Peninsula, western Bay of Plenty, Marlborough and areas of the Canterbury High Country and foothills during today and early Wednesday. The heaviest falls are then expected about the Hawkes Bay and Gisborne Ranges during Wednesday and Thursday, where up to 250mm is expected to accumulate over a 48 hour period.

People are advised that these rainfalls can cause rivers and streams to rise rapidly, surface flooding, slips and make driving conditions hazardous.

Additionally, the low moving south over the upper North Island tonight, is expected to bring a period of severe east to northeast gales with gusts up to 120 km/h to parts of Northland, Auckland and the Coromandel Peninsula, with westerly gales behind the low affecting parts of Northland.

Winds of this strength have the potential to bring down trees, damage powerlines and unsecured structures.
