Thanks for following our live blog through the afternoon.
The clean-up continues after thunderstorms hit Sydney, the Illawarra, Hunter and Central Coast, causing roofs to be ripped from homes, trees and branches to fall, and power lines to come down.
Buses are replacing trains on part of the Hunter and Central Coast line, after lightning strikes affected signals on the tracks, and planes had to be diverted from Sydney Airport as lightning struck.
Power is starting to come back on in some regions, but crews are expecting to work through the night to get power switched back on in the remaining areas.
More storms are expected for Sydney tomorrow afternoon, which have the potential to be as severe as today.
