Wednesday’s destructive storm was lit up by flashes of lightning, with more than 70,000 strikes recorded within 100 kilometres of the CBD.

A huge line of storms crossed New South Wales overnight, causing power outages, flash flooding and almost 2 million lightning strikes.

Footage shows a dramatic lightning storm seen above Sydney in New South Wales, Australia, as at least one person was killed in the storm. Officials said that an unstable airmass combined with an upper trough produced wild weather across large swathes of the state late Wednesday.
