* Stay safe by avoiding dangerous hazards, such as floodwater, mud, debris, damaged roads and fallen trees.
* Be aware - heat, fire or recent storms may make trees unstable and more likely to fall when it's windy or wet.
* Check that loose items, such as outdoor settings, umbrellas and trampolines are safely secured. Move vehicles under cover or away from trees.
* Stay indoors and away from windows.
* If outdoors, move to a safe place indoors. Stay away from trees, drains, gutters, creeks and waterways.

* Be aware that in fire affected areas, rainfall run-off into waterways may contain debris such as ash, soil, trees and rocks. Heavy rainfall may also increase the potential for landslides and debris across roads.
