Another night of extreme rain has flooded entire streets in the Australian coastal metropolis of Sydney. The Warragamba dam, which is responsible for supplying drinking water to the city of over a million people, overflowed on Saturday morning.

In more than 150 cases, residents of the state of New South Wales had to be rescued from their houses or cars trapped by the water. Landslides occurred locally and large boulders landed in the middle of roads on slopes. Authorities expect the risk of flooding to continue for days due to water draining from higher ground and dams.
