Powerful, potentially-damaging winds have started to arrive in Wellington and Wairarapa but the worst is yet to come.
MetService is warning of gusts up to 120kmh overnight tonight with potential to topple power lines and trees.
By 12.30pm today gusts of 100kmh had been recorded at Kelburn in Wellington and the State Highway 2 Rimutaka Hill Rd, between Wairarapa and Upper Hutt, MetService forecaster Dan Corbett said.
But the worst would come late tonight and early tomorrow morning.

Service forecaster Sarah Garlick said as the ''pretty extreme'' northwest wind increased later this afternoon, so would the temperature, which would peak at about 15degC in Wellington and 16C Wairarapa.
This was because the wind was coming in the form of a ''warm air stream'' from the northwest.
The wind was enough to bring down power lines and trees. Drivers of high-sided vehicles should also be careful, she said.
The wind was fairly typical for this time of the year.
Hawke's Bay was under watch for severe northwest gales later tomorrow, while Taranaki and the Central Plateau are in for potential heavy rain on Thursday.
In Wellington, the powerful wind and relatively warm temperatures would stick around tomorrow, when there could also be some heavy showers, before the wind and heavy rain let up on Thursday.
Fine weather was forecast for Wellington both days this weekend.
Just last week, southerly winds tore through Wellington with 150kmh gusts recorded in Cook Strait and on Mt Kaukau, MetService said.
Gusts of 110kmh were recorded at Kelburn and 100kmh at Wellington Airport.
Damage included a window blown out in central Wellington, a trampoline blown away in Titahi Bay, a tree down in Johnsonville and a roof lifting in Island Bay.
NZTA this morning issued a warning for motorists to beware of high winds on the State Highway 2 Rimutaka Hill Rd, between Wairarapa and Upper Hutt.
