Sydney has been lashed by intense rain and strong winds that have caused trees to fall on roads and powerlines to come down.
NSW Emergency Service (SES) responded to 377 calls for assistance in the greater Sydney area, with parts of the northern beaches and the North Shore most affected.
There were 13 flood rescues across Sydney, mostly for people trapped in their vehicles by flash flooding.

Meanwhile, students from St Madeleine's Primary in Kenthurst have been told to stay home today due to road closures inhibiting access to the school.

"We're scared of going inside," Mohammed said.
"My little sister she's seven, she screamed so loud she was shaking and she's still so scared.
"I've never seen her run out like this, she thought she was going to die, we all thought we were going to die."

Motorists are being warned to allow extra travel time and drive to the conditions, with more rain forecast today.
SES spokesman Neil Wiblin said emergency officers were kept busy overnight.
"The main type of jobs that we saw were trees and branches down due to the strong winds, followed by roofs damaged and leaking, and the heavy rain also caused localised flooding in a number of areas as well as road closures," Mr Wiblin said.
Fire and Rescue NSW superintendent Adam Dewberry said firefighters responded to a number of emergency incidents due to the storm.
"Flooding in homes, flooding in unit blocks, several car crashes … numerous wires down, wires arcing where our firefighters go to these areas, render them safe, set up exclusion zones to prevent people becoming electrocuted," he said.
There were 51 call outs for assistance in the Warringah-Pittwater area, 42 in Orange, 33 in Queanbeyan, 21 in Ku-ring-gai and 17 in Sutherland.
