Heavy rainfall and damaging winds have the potential to cause flash flooding across the region tonight, the latest Bureau warning indicated shortly after 11am on Monday, February 5.
Expected in the state's northwest today, conditions are expected to extend to the southern and central ranges during the evening.
Six-hourly rainfall totals sit between a likely 50 and 80 millimetres at this stage.
Experts say the turn in weather events comes from ex-tropical Cyclone Kirrily, which is currently centred over the far southwest of Queensland before moving south-east to gradually weaken over central parts of NSW early Tuesday.
Conditions are expected to clear by Tuesday afternoon.
Those west of Parkes in the Central West remain on alert, an "intense rainfall" forecast pointing to the potential for "dangerous and life-threatening flash flooding".
The full list of locations which may be affected include: Bourke, Canberra, Cobar, Goulburn, Orange and Tibooburra.
All regions issued these warnings mention: Southern Tablelands, South West Slopes and parts of Central Tablelands, Central West Slopes and Plains, Riverina, Lower Western, Upper Western and Australian Capital Territory Forecast Districts.
More information (under 'Flood Watch') for the far west and south west catchments can be accessed online.
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.
- Move vehicles under cover or away from trees.
- Secure or put away loose items around your house, yard and balcony.
- Keep at least 8 metres away from fallen power lines or objects that may be energised, such as fences.
- Trees that have been damaged by fire are likely to be more unstable and more likely to fall.
- Report fallen power lines to either Ausgrid (131 388), Endeavour Energy (131 003), Essential Energy (132 080) or Evoenergy (131 093) as shown on your power bill.
- 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.
The Bureau's next Severe Weather Warning will be issued by 5pm on Monday, February 5.
