A severe storm that tore through Sydney and smashed the Sutherland Shire suburb of Kurnell brought with it unprecedented, record wind-speeds, as multiple storm cells moved across the state's coast.
The Bureau of Meteorology told The Huffington Post Australia the 213km/h winds recorded in Kurnell on Wednesday was the strongest recorded in NSW since Richmond was buffeted by 170km/h winds in 2001.
The storm wreaked havoc in Kurnell before moving north, while storm cells rained down on the Blue Mountains, Hawkesbury and Central Coast regions. Heavy rains caused a roof to collapse at Westfield Bondi Junction, forcing shoppers to evacuate.
Sydney's desalination plant at Kurnell was evacuated after workers were injured and the plant was damaged, while a hospital in Sutherland reportedly had to be evacuated.
BOM forecaster Christopher Webb told The Huffington Post Australia a storm warning for the Sydney metropolitan area had been cancelled late in the afternoon as the storm headed inland.
Police said Kurnell is currently without power and sewerage and services may not be able to be restored until Thursday.
An Evacuation Centre has been established for residents affected by the storms at Cronulla Sutherland Leagues Club, 461 Captain Cook Drive, Woolooware.
Earlier, terrifying footage emerged of airborne branches, howling winds and heavy rains during the 213 km/h tornado as it smashed Kurnell, showing the skies erupting with lightning through dense cloud as the wind whips debris.
The second wave of a severe storm cell then barreled down on Sydney and surrounding areas, after an earlier cell swept north through the city amid reports of a tornado, hail, heavy rains flash flooding.
In the footage people can be heard screaming as debris can be seen hitting a metal fence at high speed, as a group apparently stand under a shelter as the storm rages.
"(I've) never seen anything remotely like this before," Andrew McGregor, who took the video, told HuffPost Australia.
"Been sent home from work, no power and something big happening at the Kurnell oil refinery," he also wrote on Facebook.
He described his colleagues as "all good."
State Emergency Services has responded to more than 200 calls for help, mainly for roof damage and fallen trees and power lines.
The emergency department of Sutherland hospital was also evacuated amid fears of an electrical fire.
Police asked people in storm-affected areas to leave work early to avoid traffic and transport delays.
Destructive winds, large hailstones, heavy rainfall and flash flooding pummeled the Sydney coast around Kurnell shortly after 10am this morning.
Winds tore roofs from buildings and residents took to social media to share images of the damage.
The storm passed through the city's south at about 10am, before progressing through Hornsby, Ryde and Terrey Hills before heading out to sea.
