A pregnant woman whose waters broke has been ferried through floodwaters by emergency responders after rising rivers cut a NSW town in two.
Forbes in the NSW central west is bracing for the overflowing Lachlan River to rise to a possible peak of 10.8 metres on Saturday, a high-water mark not reached since 1952.
Ashley Sullivan, from the State Emergency Service, said the water was already close to reaching the expected peak on Saturday morning and about 500 homes in Forbes were under evacuation orders.
