A slip had already fallen on to the front of a car on Ohiro Rd in Brooklyn.
A picture provided to the Herald showed the slip, which had spilt on to the bonnet of a small car.
Wellington City Council said contractors were on route to the incident and traffic management has been actioned.
Another slip came down on the westbound lane of State Highway 58 earlier this morning, but has since been partially cleared.
Contractors are also attending to a slip on Onslow Rd, while lighting crew head to Tory St to deal with a leaning street light, and crews work on a downed tree in Chamberlain Rd, Karori.
Wreda regional manager Jeremy Holmes said winds up to 120km/h were forecast, but this was not unusual for Wellington.
The rain was more of a concern, as it could lead to surface flooding and rapidly rising streams and rivers.
A council spokeswoman said people should make sure their gutters are clear and trampolines tied down.
The MetService has issued a strong wind warning and a heavy rain warning for the region which was also affecting ferries travelling across the Cook Strait.
Later in the afternoon southerlies were expected to rise to gale force, gusting as strong as 120km/h in exposed places through into the night.
Bluebridge, which operated ferries on the Cook Strait, said with wild weather predicted passenger sailings today and tomorrow could be affected. They have cancelled three sailings so far, including the 7pm trip to Picton.
Interislander strategy manager Peter Wells said they were monitoring the situation.
"As a precaution the 6.45pm sailing from Picton today (Monday) will carry only freight.
"Affected passengers have been advised, and offered alternative sailings.
"We have also advised our customers of the possibility some Interislander sailings may need to be cancelled because of the weather.
"This is unfortunate, but safety is our top priority."
A lot of areas of the country are currently affected by the weather system moving over the country, Metservice meteorologist Angus Hines said
Strong cold southerlies were expected across the country as the system moved north.
A strong wind warning was in place for central parts of the country including the Kaikoura coast, Wellington and the Marlborough Sounds.
A strong wind watch was in place for Christchurch and the Banks Peninsula and the Wairarapa south of Martinborough.
It wasn't just wind, there was a heavy rain watch in place as well.
This affected Wellington and the southern Wairarapa.
MetService meteorologist Mark Bowe said the key weather feature to watch out for was the wind.
"The key feature today is the wind warnings, they will kick in at 4pm until tomorrow morning."
As the complex low moved through the country snow was falling to 500m in the South Island and this afternoon snow was expected to fall to 1000m in the North Island.
"That will affect places like the Desert Rd."
From Northland to Taranaki and across to Taupō and Bay of Plenty, there was a moderate risk of thunderstorms developing from about dawn.
"A lower risk of thunderstorms extends to most remaining areas of the North Island north of Wellington and to western Nelson and Buller in the northwest of the South Island," Meteorologist Andy Best said.
The forecast was not unexpected as the transition from winter to spring often brought turbulent weather, Best said.
"Seas are still relatively cold around Aotearoa, but as the subtropics start heating up quickly and temperatures remain cold to the south, the thermal contrast can result in strong spring winds.
"We can also still experience very cold outbreaks, as southerly changes push up the country from the Southern Ocean."
Road snowfall warnings are in place for Desert Rd (SH1), Lewis Pass (SH7), Arthur's Pass (SH73), Porters Pass (SH73), Haast Pass (SH6), Lindis Pass (SH8), Crown Range Rd and the Dunedin to Waitati Highway (SH1).
