For people in parts of Lower Western, Upper Western and Riverina Forecast Districts.

Issued at 8:46 pm Monday, 25 November 2024.

Severe thunderstorms in the west.

Weather Situation: Severe thunderstorms are developing in a very moist unstable airmass under the influence of an upper trough. Heavy rainfall is most likely where multiple storm cells pass over the same location.

Severe thunderstorms are likely to produce heavy rainfall that may lead to flash flooding in the warning area over the next several hours. Locations which may be affected include Wilcannia, White Cliffs, Ivanhoe, Menindee and Fowlers Gap.

30.8 mm recorded at Tibooburra in the 30 minutes to 7:46 pm.

The State Emergency Service advises that people should:
* Keep clear of creeks and storm drains.
* Don't walk, ride your bike or drive through flood water.
* 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.
* Unplug computers and appliances.
* Avoid using the phone during the storm.
* Stay indoors away from windows, and keep children and pets indoors as well.
* Stay vigilant and monitor conditions. Note that the landscape may have changed following bushfires.
* For emergency help in floods and storms, ring the SES (NSW and ACT) on 132 500.
