Cyclones, storms and floods

Every year Australia’s tropical north is subject to cyclones, severe storms and strong winds often with driving rain and many lightning strikes. Central Australia experiences its heaviest rainfall during the Summer months and can be subjected to storms and strong winds.

Although many of us are accustomed to living in the Territory climate we should not become complacent about this.

Our Get Set 4 the Wet/Summer guide will help you prepare your home and family - don't wait until a severe weather warning is announced to take action.

If a cyclone or severe storm does hit, it could affect power supply and, potentially, water and sewerage services for several days.

Power and Water's first priority is to ensure public and employee safety. Crews will be on standby to go out as soon as the storm has passed.

The following safety tips could make a difference during a storm or cyclone. Read them carefully and share them with your family and friends. It's particularly important that children are aware of the dangers.

Fallen powerlines

Trees, high winds and flying debris can bring down overhead powerlines. Take care when cleaning up and if you find something you think may be a powerline, don't take any chances. Assume every fallen powerline is 'live' and dangerous even if it is not sparking. Stay well away, warn others and call 000 or our emergency number 1800 245 090.


Never swim in floodwaters. There may be unseen 'live' and dangerous electrical wiring or fallen powerlines in or around the water which may be hidden by debris. There is the chance floodwaters are contaminated by sewerage outflows.


Don't connect portable generators to your house or office unless a Northern Territory licensed electrical contractor has installed an isolating switch. Appliances can be plugged directly into the generator but always read the manufacturer's instructions carefully.

For more information, refer to Generator safety and use.

Water and electricity

Never use electrical appliances that may have been affected by water. Have them checked by a Northern Territory licensed electrical contractor before use. If water enters your ceiling do not touch any lights or switches, call a Northern Territory licensed electrical contractor immediately.
