For people in Metropolitan, Illawarra and parts of Hunter and Central Tablelands Forecast Districts.
Issued at 10:59 am Monday, 4 July 2022.
Threat of heavy rainfall will continue to ease today on and east of the ranges across central NSW.
Weather Situation: A trough over the central coast will continue to direct a moist onshore flow, causing moderate to possibly heavy rainfall at times in areas near and to the south of the trough. The trough is forecast to move northward later today with drier air moving up the New South Wales coast in its wake.
Although rainfall rates have generally eased, localised HEAVY RAINFALL which may lead to FLASH FLOODING remains possible until later this evening over the Illawarra, Blue Mountains, Sydney Metropolitan, and parts of Hunter (including Central Coast) districts. Isolated three-hourly rainfall totals between 50 to 75 mm are possible.
Rainfall over the Sydney Metropolitan and Illawarra districts will ease this afternoon as showers and rain areas contract northward to the Hunter district. Light to moderate rainfall is expected to continue across the Hunter into Tuesday.
Rainfall will further contribute to flooding already being experienced, and maintains the potential for landslides.
Damaging wind gusts are no longer expected across the warning area. However, strong and gusty winds may still provide the risk of trees toppling in softer and very saturated soils, particularly about the coastal fringe and ranges.
Various Flood Warnings and Watches are current, including some MODERATE to MAJOR flooding in some high population areas, so please refer to those flood warnings at http://www.bom.gov.au/nsw/warnings/ and heed the advice of authorities.
A separate Severe Weather Warning for Damaging Surf is also current along parts of the central coastline.
Locations which may be affected include Newcastle, Gosford, Cessnock, Maitland, Sydney, Penrith, Parramatta, Wollongong, Nowra, Bowral, Campbelltown, Katoomba and Lithgow.

The State Emergency Service advises that people should:
* Don't drive, ride or walk through flood water.
* Keep clear of creeks and storm drains.
* If you are trapped by flash flooding, seek refuge in the highest available place and ring 000 if you need rescue.
* Be aware that run-off from rainfall in fire affected areas may behave differently and be more rapid. It may also contain debris such as ash, soil, trees and rocks.
* After bushfires, heavy rain and the loss of foliage can make the ground soft and heavy, leading to a greater chance of landslides.
* Stay vigilant and monitor conditions. Note that the landscape may have changed following bushfires.
* For emergency help in floods and storms, ring your local SES Unit on 132 500.
