A coastal low is bringing damaging winds, monster swell and heavy rainfall from the Hunter to the South Coast of NSW, with the wild weather expected to peak in Sydney this afternoon.
- The low pressure system has already caused flooding in Newcastle
- The BOM said the wild weather could see wind gusts of up to 60km hit Sydney
- Wild surf is pummelling the NSW coast, causing coastal erosion fears
Since last night, the NSW State Emergency Service (SES) said they had already responded to 199 calls for help in the Sydney region, and almost 600 state-wide.
The dangerous low-pressure system formed off the Illawarra coast yesterday and brought gusts of up to 90 kilometres an hour overnight in some places.
“Near the Sydney coast, wind gusts are already 40 kilometres an hour but they’re going to reach a coastal high of 50-60 kilometres a hour,” Bureau of Meteorology (BOM) meteorologist Shuang Wang forecasted.
Bellambi in Wollongong experienced a gust of 91 km/h at 1:00am this morning, while Kiama on the state’s South Coast recorded the same at 1:41am.
Sydney’s Observatory Hill clocked about 72 millimetres of rainfall from 9:00am yesterday morning, while Sydney’s Olympic Park saw 76.2mm.
In the Sydney basin, Wahroonga received 114mm, while Prospect, south-west of Blacktown, received 101mm.
Elsewhere, Nords Wharf experienced top falls since 9:00am yesterday with 187.5mm falling in the Lake Macquarie suburb.
Jervis Bay experienced 178.6mm of rain, while Wyee on the Central Coast has received 167.5mm of rain.
Very heavy surf conditions are pummelling the east coast, with fears of coastal erosion reignited as at least 18 Wamberal homes remain damaged from last week’s wild weather.
Residents watched on nervously as workers from the Central Coast council piled up about 150 rock-filled bags to stopper the erosion from the wild seas.
The hazardous surf warning applies from the South Coast to Newcastle, and the BOM discouraged anyone from entering the swell.
“Beach conditions in these areas could be dangerous and people should stay well away from the surf and surf exposed areas,” the BOM warned.
Heavy rainfall and flash flooding have already hit Newcastle overnight, with 10 people rescued from a bus that became submerged in floodwaters on Callaghan Drive.
The SES has warned the Hawkesbury may experience flash flooding also, while the Illawarra and South Coast regions are on high flood alert.
The BOM said locations which may be affected include Sydney, Wollongong, Nowra, Bowral, Batemans Bay and Eden.
Damaging wind gusts over the Southern Highlands and the coastal ranges of South Coast are also possible.
Buses were replacing F1 Manly ferry services between Circular Quay and Manly on Monday morning due to the weather conditions.
Trains were also suspended on the South Coast Line between Wollongong and Port Kembla on Monday morning and replaced by buses due to flooding.
The dangerous low-pressure system is expected to ease later this evening or early tomorrow as it weakens.
