Sydneysiders are mopping-up after half a month's worth of rain pelted the city in one day, with the SES responding to 250 calls.
More rain is expected in the city on Wednesday with showers easing through the day. But Wollongong could be hit by thunderstorms during the morning according to the weather bureau.
Overnight the Illawarra region copped the heaviest rainfalls, with the SES carrying out two flood rescues in the area with people trapped in cars. Since 8pm on Tuesday the SES has received 80 calls for help around the area after more 120mm of rain fell in the past 24 hours.
Sydney was pelted with rain on Tuesday morning, with the innerwest suburb of Marrickville receiving 53mm of rain falling in just one hour between 10am and 11am as the storm cell hit.
Tuesday's showers measured half the average rainfall for February.
The SES carried out 19 flood rescues mainly in Sydney's innerwest and received 250 calls for help, a spokeswoman said.
