Sydney has been hit by significant flash flooding this morning, thanks to a severe storm system which is expected to dump more than a month’s worth of rain on the city in just a day.

Footage shared on social media shows the direct impact of the storm, which has caused traffic chaos, delayed flights to and from Sydney Airport, and threatens to damage properties around the city.

The State Emergency Service reports that it has already received six flood rescue calls from across the city. Drivers have been reminded not to attempt to pass through flooded roads, even if the water appears shallow.

Train services have been impacted by the storm, and Lewisham station on the T2 line has experienced significant flooding.

Commuters are advised to check up on the Transport NSW site for the latest information regarding their services.

The storm has also caused delays at Sydney Airport, which reduced operations to just two runways before suspending operations in light on the deluge. Travellers intending to depart through both the airport’s domestic and international terminals have been advised to expect significant delays and cancellations.

The storm, which is set to drop up to 100mm of rain across much of Sydney, is expected to continue until at least the afternoon.

In some places, the storm has already surpassed monthly rainfall expectations: the Observatory Hill weather station already notched nearly 85mm of rainfall before 7am, surpassing the November average of 83.8mm.

Stay safe, folks.
