A spokeswoman from the State Emergency Service said around 470 incidents were logged last night.

An SES spokesman, Phil Campbell, said that volunteers were kept busy across Sydney, the Illawarra and the Blue Mountains last night.

"The majority involve roof damage from fallen trees and branches, trees across power lines and trees across fences and driveways,'' he said.

Among the more severe incidents was a roof ripped off a home in Windsor that took out power lines on the street and a large falling tree that damaged five cars and an ambulance in Liverpool.
