Two men are missing after a car crashed into a river in northern Sydney on Wednesday night.
Emergency services were called about 11:50pm to the Macdonald River, near Settlers Road, St Albans, about 20 kilometres north of Wisemans Ferry, following reports a car had entered the river.
Officers attached to Hawkesbury Police Area Command found that a car had crashed into the river before one passenger exited the vehicle and reached the riverbank.
The man, in his 20s, was assessed by paramedics at the scene but did not require further treatment.
Police have been told two other men were in the car at the time and are yet to be accounted for.
The State Emergency Service (SES) and NSW Rural Fire Service have been involved in the search for the two men.
Residents across New South Wales have been warned to prepare for more wet weather with a complex system expected to hit the state from Thursday.
The heaviest falls are due on Thursday morning, with isolated showers in some areas potentially reaching up to 120 millimetres.
The Bureau of Meteorology said the exact location of the system was hard to predict.
However, minor to moderate flooding is possible for the Mid North Coast, Northern Rivers, Northern Tablelands, North-West Slopes and Plains, parts of the Hunter and parts of Greater Sydney.
