Three elderly people were found dead just north of Sydney Tuesday while two elderly women are missing after a car was swept away in Maitland. Australia's weather agency has warned of more torrential rain and high winds while New South Wales State Premier Mike Baird has declared a natural disaster for some of the worst hit areas.
