NSW flooding: SES hit with 447 calls for help amid rain deluge, Warragamba Dam begins spilling

Flood warnings have been issued for much of the east coast of New South Wales as heavy rainfall continues to lash the state.

Overnight, the NSW State Emergency Service (SES) received 447 calls for assistance, including almost 50 flood rescues.

WaterNSW also confirmed that the Warragamba Dam began leaking at 4.20am on Friday.

Some areas of the New South Wales south coast could see isolated rainfall of up to 130 mm next Thursday.

Between 9am on Thursday and 5am on Friday, Cringila was hit by 206mm, Port Kembla was devastated by 197mm and Wollongong experienced showers of 146mm.

Between 8am on Thursday and 1am on Friday, the NSW SES Wollongong Unit responded to 27 rescues and 110 other incidents.

A weakening low pressure system will continue to bring rain to the Illawarra and South Coast regions throughout Friday before conditions are expected to ease in the evening.

Minor to moderate flood warnings are also in place for Menangle Bridge, Penrith, North Richmond and Windsor, while authorities are nervously monitoring the Hawkesbury and Nepean rivers.

The Bureau of Meteorology reports that the Hawkesbury Nepean Valley experienced up to 147 heavy rainfall events in the 24 hours to 5am on Friday, with more heavy rainfall on the way.

A “watch and act” warning is in place for homes in Menangle, in the Macarthur region of New South Wales. Flood levels at Menangle Bridge are expected to reach 9.2 metres on Friday morning and 10 metres by midday.

Evacuation orders were also issued for lower-lying homes in Picton’s CBD and Stone Quarry Creek.

The NSW SES advises people to closely monitor the changing situation and avoid flooding.

Parts of Penrith in western Sydney could also be hit by minor flooding from midday; the level of the Nepean River could reach 3.9 metres.

Since 9am on Thursday, 56.2mm of rain has been recorded on Sydney’s Observatory Hill.

There may also be minor flooding on the Cooks River near Tempe Bridge in the south of the city. High tide is expected for Friday evening.

The neighbouring suburb of Windsor and its surrounding areas could be affected by rising water levels from Friday evening. Forecasts suggest that the Hawkesbury River will reach a minor flood level (5.8 m) overnight Friday into Sunday and a moderate flood level of 7 m by Saturday morning.

Motorists in Sydney’s southern suburbs were also warned. The department warned that flooded roads and reduced visibility would lead to dangerous driving conditions and urged motorists to exercise “extreme caution” ahead of the long weekend.

However, a better weather forecast should ensure that the rain on Saturday and Sunday disappears.
