The State Emergency Service advises that people should:
* If driving conditions are dangerous, safely pull over away from trees, drains, low-lying areas and floodwater. Avoid travel if possible.
* 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.
* Stay away from fallen powerlines - always assume they are live.
* 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.
* Stay informed: Monitor weather warnings, forecasts and river levels at the Bureau of Meteorology website, and warnings through VicEmergency website/app/hotline.
