For people in Illawarra and parts of Metropolitan, South Coast, Central Tablelands and Southern Tablelands Forecast Districts.

Issued at 10:59 pm Thursday, 6 June 2024.

Heavy rainfall to continue over the Illawarra and surrounds tonight, easing later on Friday.

Weather Situation: A surface trough extending through northern parts of the Illawarra will continue to draw a humid southeasterly airmass to its south, currently generating areas of heavy rainfall about the northern parts of the warning area. This trough and the associated southeasterly flow is expected to hover about the central and northern Illawarra through Friday morning, before tracking southward and weakening during Friday afternoon and evening.

HEAVY RAINFALL which may lead to FLASH FLOODING is forecast for the Illawarra and parts of the South Coast, Southern and Central Tablelands, and Metropolitan districts for the remainder of the day and through Friday afternoon. Scattered six-hourly rainfall totals between 50 and 100 mm are likely with isolated totals around 150 mm possible. Scattered 24-hourly rainfall totals between 100 and 150 mm are also likely with isolated totals around 250 mm possible.

The area of heaviest rainfall has recently shifted north along the coast between Kiama and Wollongong, with further northward movement expected throughout the night. Heavy rainfall may redevelop again in more southern parts of the warning area during Friday morning, as the trough retrogrades southwards. Conditions are expected to ease throughout during Friday afternoon and evening.

Flood Watch is current for parts of the Central Coast, Sydney Metropolitan Area, Illawarra and South Coast while various Flood Warnings are also current. Please refer to

* 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.
