Weather Situation: A complex low pressure system is currently located near the South Australia and New South Wales border. This system is forecast to deepen tonight while remaining slow-moving before moving east to southeast into western and central parts of the state during Thursday afternoon and evening.

HEAVY RAINFALL which may lead to flash flooding is forecast to develop overnight tonight and into Thursday morning over western parts of the Lower Western district. It is then expected to extend north and eastward into parts of the Upper Western and Riverina districts during Thursday afternoon and evening. Six-hourly rainfall totals between 40 to 60 mm are possible.

A Flood Watch is current for inland catchments. See http://www.bom.gov.au/nsw/warnings/ for more information.

Locations which may be affected include Coombah, Hay, Wilcannia, Broken Hill, Ivanhoe, Menindee and Balranald.

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.
