Affected Areas

The warning specifically covers parts of the Lower Western and Upper Western Forecast Districts. Locations that may be affected by these conditions include Wentworth and surrounding far southwestern regions.

What You Should Do

The State Emergency Service (SES) advises residents in the warning area to take the following precautions:

• Do not 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 call 000 if you require rescue.
• For emergency help in floods and storms, contact the SES at 132 500.

Expected Conditions

Tropical humidity on the southeastern flank of a low-pressure system in central Australia is expected to generate a broad region of rain with embedded thunderstorms. Heavy rainfall is forecast which may lead to flash flooding. Six-hourly rainfall totals between 40 to 60 mm are possible in the far southwestern parts of the affected districts.

Timeline

Heavy rainfall is expected to develop about the far southwest this afternoon and continue overnight tonight. While rain rates may ease temporarily during the day on Sunday, they are expected to increase again from Sunday evening into Monday as a cold front approaches the region. The next update from the Bureau of Meteorology is scheduled to be issued by 11:00 pm AEDT Saturday.
