Drenching rain in Sydney is forecast to continue into next week after some areas were inundated with more than a month's worth of precipitation in 24 hours.
The deluge caused flash flooding in parts of the city, prompting hundreds of requests for help to the NSW State Emergency Service on Tuesday and Wednesday.
Emergency Services Minister Steph Cooke said on Wednesday that the SES received 1323 calls in 24 hours with 40 children being evacuated from a childcare centre in Marrickville, in Sydney's inner west.
