Thousands of people were without power Friday night after electrical storms brought hail, heavy rain and strong winds to the Sydney region during the afternoon.
Emergency crews have restored power to around 14,000 homes and businesses but 21,000 across the Sydney, Central Coast and Hunter regions remained without power at 9pm AEDT.
Strong winds reaching up to 93km/h lashed Sydney on Friday afternoon, tearing the roof off a home in the inner-Sydney suburb of Lilyfield.
One resident said she saw the roof of the three-storey apartment fly off, taking down nearby power lines.
"I was looking at it and I thought I should shut the windows," she told 9NEWS.
"I realised it was worse than I’d thought and then the roof fell off."
A 36-year-old man was struck by lightning while at a construction site at Rouse Hill just before 4pm.
He was transported to Westmead Hospital in a stable condition.

Residents in western and southern areas bore the brunt of the system, which pelted Penrith with hailstones shortly after 2pm before damaging winds and heavy rain hit the city and surrounding areas.
