Sydney battered by violent stormsMellissa Mackellar, Friday November 9, 2012 - 10:39 EDT
Intense thunderstorms brought soaking rain, large hail and damaging winds to parts of the city's west on Thursday and there is a chance of more storms today.
Power was cut to thousands of homes in the south and south-west, trees were knocked down and the roof of the Carnes Hill Shopping Centre collapsed.
A storm cell moved in from the west before taking a right turn and becoming severe near Richmond. It then headed south, hitting Penrith just after 4pm and dumping 17 millimetres of rain in just 10 minutes. Wind gusts of 107km/h were also recorded in the Penrith area and there were reports of large hail. In total Penrith had 21mm of rain in the 24 hours to 9am on Friday, which was their heaviest rain since June.
Elsewhere, Ingleburn picked up 37mm of rain while Canterbury and Riverview had 15mm in the gauge.
Early on Friday morning parts of the city's north also had a drenching. The heaviest falls were in Castlecove with 34mm, while 20mm fell in Frenchs Forest and 13mm in Chatswood.
The main axis of the trough will move north during Friday, causing the area of greatest instability to contract to the northeast of NSW. There is still a risk of thunderstorms for Sydney today, however they are much less likely than yesterday.
