More than 1600 calls to SES, 50 rescues in flash-flooding
UPDATE: The SES has received more than 1600 calls for help across the state since flash flooding began in New South Wales on Monday and carried out more than 50 rescues - a figure authorities expected to grow.
Emergency service crews have doorknocked residents in Lake Conjola on the south coast, warning them to evacuate should floodwaters continue to rise.
The Bureau of Meteorology says the peak intensity of the low pressure system is expected to hit tonight before moving away and weakening through Wednesday.
Residents downstream from the Jerrara Dam, near Kiama, were told to leave their homes amid fears the structure would fail.
A nearby primary school was also closed.
A "mini tornado" damaged buildings and knocked down trees and powerlines in Dubbo late on Monday.
[12:00 PM] NSW bracing for more storms after floods, 'tornado'
EMERGENCY crews are bracing for more severe weather in New South Wales after a storm cell caused flash flooding, damage to homes and a "mini tornado" in the state's central west.
The State Emergency Service (SES) was working to rescue three adults and two children who are stuck by a flooded causeway at Kiama on the south coast, one of more than 35 rescues due to flash flooding overnight.
The SES has responded to about 600 calls for help across the state's west, Illawarra and in southern parts of Sydney.
The SES has brought in flood rescue operators to assist with possible evacuations near the Jerrara Dam and a Lifesaver Rescue Helicopter has moved into the area, west of Kiama.
