If you’re in a flood-prone area of New South Wales, check the live forecast above and your local SES warnings now, because heavy rain is the primary trigger for these events across the state’s river systems.
What should I do during a flood warning?
Your first step is to monitor the live forecast above and heed evacuation orders from the NSW State Emergency Service. Never drive, walk or ride through floodwater — just 15 centimetres of moving water can knock you off your feet, and 60 centimetres can float a car. Move livestock, pets and valuables to higher ground before roads become impassable. Keep your emergency kit (torch, batteries, first-aid supplies, drinking water) ready to go.
Which areas are most at risk in NSW floods?
The northern rivers, Hawkesbury-Nepean valley and inland catchments such as the Lachlan and Murrumbidgee see the most frequent flooding. The Bureau of Meteorology issues river height and flood warnings for these basins, often days in advance. If you live near a creek or low-lying area, it’s worth checking our severe weather warning page for real-time updates. For broader conditions across the state, head to our Australia weather hub.
How do I know if my property is in a flood zone?
Check the NSW Flood Data Portal or your local council’s flood mapping tool. You can also ask a real estate agent or surveyor for a property-level flood risk report.
What’s the difference between a flood watch and a warning?
A flood watch means conditions are favourable for flooding in the next few days — start preparing. A flood warning means flooding is imminent or already occurring; you should act immediately.
Can I still travel during a flood warning?
No. Roads can become cut without warning. Avoid all non-essential travel in affected areas, and never drive around road-closed signs. Turn around, don’t drown.
