The anticipated 'weather bomb' that's due to hit the central of New Zealand over the next two days has begun showing its teeth.
High winds have been causing trouble on coastal roads on the South Island's west coast where authorities are urging drivers to take care.
'Heaviest is yet to come' - MetService
Despite rainfall arriving on cue, the heaviest is yet to come, MetService meterologist Lisa Murray said on RadioLIVE's Drive show on Wednesday.
Heavy rainfall has fallen along the West Coast, where 50mm and 70mm of rain fell overnight in Hokitika and Greymouth, while up to 100mm of rain fell on Arthurs Pass.
Surface flooding is now developing along the coast and inland between Hokitika and Greymouth, forcing road closures.
Properties in Hokitika have begun experiencing water creeping up to their front yards, adding to the risk of the public and homeowners.
Authorities are warning motorists to check the weather forecast before they travel and to adhere to warnings and signage.
Strong winds and heavy rain is expected to hit the northern parts of the South Island and Wellington late on Wednesday and into Thursday where wind gusts are expected to reach at least 160kmh.
Wellington public transport stopped
Trolley buses in Wellington have been cancelled as the Capital battens down the hatches for the weather bomb hitting New Zealand on Wednesday.
Services are being replaced by diesel buses, Metlink says, and it is not expecting any major disruptions to its rail timetable.
Preparing for high winds
MetService is advising the public in the affected areas to tie down and loose outdoor furniture or tools before the wind arrives.
They also advise keeping all windows and doors closed unless necessary. High-sided and light vehicles such as motorbikes and vans are encouraged to park in garages and out of the wind so they don't blow away or cause damage.
Public transport can expect delays or cancellation over the next two days.
Boaties urged to stay off the water
Southlanders have been warned to stay away from the water until the forecasted storm has passed.
"Unless absolutely necessary, stay off the water until the significant weather event has passed," says Southland harbourmaster Lyndon Cleaver.
Mr Cleaver is also asking boaties to check their equipment around Stewart Island and Bluff and make sure their boats are secure.
Wind gusts upto 130km/h are expected in Southland, Fiordland and Stewart Island over the next two days.
