Storms cause flash floods and power outages

Fierce storms have toppled large trees into houses and caused flash floods across NSW, emergency services said yesterday.

A State Emergency Services (SES) spokesman said suburbs in Sydney's west had been badly hit, but the storm was not the worst this year.

"In the south-west [of Sydney] we've had 110 requests for assistance, mostly in Ingleburn but extending to Liverpool, Greenacre and Bankstown," he said.

"Ingleburn was at the epicentre with a number of large trees on homes."

Fallen trees on powerlines, roads and homes were also reported in Lake Macquarie, the upper Hunter and as far west as Lightning Ridge.
