Localised heavy rainfall possible on the South Coast and Illawarra this weekend.

Weather Situation: A coastal trough about the southeast coast is forecast to deepen into a coastal low tonight or early Sunday in response to an upper low over central parts of the state.

HEAVY RAINFALL which may lead to FLASH FLOODING may develop over the northern parts of the South Coast, southern parts of the Illawarra, eastern parts of the Southern Tablelands and far northeastern parts of Snowy Mountains districts from this morning and persist into Sunday.

Six-hourly rainfall totals between 50 and 70 mm, with isolated 100 to 120 mm possible. 24-hourly totals between 140 to 160 mm are likely and isolated falls up to 200 mm are possible over the ranges.

HEAVY RAINFALL is forecast to ease during Sunday evening.

Locations which may be affected include Nowra, Batemans Bay, Moruya Heads, Ulladulla, Narooma and Araluen.

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.
