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

Flood warnings have been issued for several parts of the NSW east coast as heavy rain continues to batter the state.

Wild weather hit the state on Thursday night as heavy rain, thunder and lightning lashed Sydney.

A “five-in-one” lightning strike hit the city at 8pm, with two bolts appearing to hit the harbor bridge.

The NSW State Emergency Service (SES) received 447 calls for help, including almost 50 flood responders.

WaterNSW also confirmed the Warragamba Dam began to overflow at 4.20am on Friday.

Areas on the NSW south coast could be affected by isolated falls of up to 130mm.

Between 9am on Thursday and 5am on Friday, Cringila was hit by 206mm, Port Kembla was battered by 197mm and Wollongong was drenched by 146mm.

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

Light rainfall will continue to bring rain to the Illawarra and South Coast regions throughout Friday before conditions are forecast to ease in the evening.

Minor to moderate flood warnings are also active for Menangle Bridge, Penrith, North Richmond and Windsor as authorities keep a nervous eye on the Hawkesbury and Nepean rivers.

The Bureau of Meteorology reports a total of 147 gusts hit the Hawkesbury Nepean Valley in the 24 hours to 5am, with heavier rainfall on the way.

Homes in Menangle, in the NSW Macarthur region, are under a ‘Watch and Take Action’ notice as floodwaters at the Menangle Bridge are expected to reach 9.2m on Friday morning and 10m by midday.

Lower-lying houses in Picton’s CBD and Stone Quarry Creek were also told to prepare to evacuate.

The NSW SES is advising people to keep a close eye on ever-changing conditions and to avoid floodwaters.

Parts of Penrith in Sydney’s west could also experience minor flooding from midday, with the Nepean River expected to reach 3.9m.

As of 9am on Thursday, Sydney’s Observatory Hill had recorded 56.2mm of rain.

Minor flooding is also possible on the Cooks River at the Tempe Bridge in the south of the city, with a high evening tide expected on Friday evening.

The neighboring suburb of Windsor and its surrounding area could be affected by rising water levels from Friday evening, with the Hawkesbury River expected to reach minor flood levels (5.8m) on Friday evening and moderate flood levels of 7m by Saturday morning.

Drivers in Sydney’s southern suburbs have also been warned. The office warned that flooded roads and reduced visibility would cause dangerous driving conditions and urged motorists to use “extreme caution” ahead of the extended weekend.

However, a better forecast is expected to keep the rain away from Saturday and Sunday.
