Four people have died and several were missing as major flooding in New South Wales (NSW) left about 50,000 people isolated by floodwaters. The record rainfall, now declared a natural disaster, has been caused by a slow-moving area of low pressure and is greater than any in living memory for some residents, according to local authorities.

Days of heavy rain in the Australian state of New South Wales turned deadly Wednesday as record floodwaters trapped people in their cars and homes.

Australian officials say record floodwaters on the country's east coast have left one person dead and three others missing, as more heavy rain is forecast in the area.
