How to Stay Safe During Severe Storms and Flooding in Australia
Australia’s weather can turn violent without much notice. A deep low-pressure system, often dragging a band of rain thousands of kilometres long, can sweep across southern states and dump more than 100 millimetres of rain in a single day. Damaging winds, hail, and flash flooding follow. Knowing what to do before, during, and after these events cuts risk and protects property.
Understand the Warnings
The Bureau of Meteorology issues several levels of alerts. A flood watch means heavy rain may cause river or creek flooding — it is a heads-up, not a guarantee. A severe weather warning signals damaging winds, large hail, or intense rain that can trigger flash floods. A flood warning tells you that flooding is occurring or imminent in a specific catchment. Never drive through floodwater. Half a metre of moving water can push a car. ABC News notes that low-pressure systems can raise wind gusts above 90 kilometres per hour across major cities, toppling trees and cutting power.
Prep Your Property Before the Storm
Start before the rain arrives. Clear gutters and downpipes so water flows away from the house. Trim overhanging branches that could fall on the roof. Secure loose items — outdoor furniture, trampolines, bins — that become projectiles in strong winds. Check your emergency kit: a torch with fresh batteries, a battery-powered radio, drinking water for three days, non-perishable food, and any medications. If you live in a flood-prone area, move valuables and documents to high shelves. Sandbags can help divert water if placed correctly at doorways. The Bureau of Meteorology’s severe weather update often includes specific advice for catchments already saturated from earlier rain, raising the risk of landslides and flash flooding.
Shelter in Place Safely During the Storm
Stay indoors and away from windows. If flooding threatens, move to the highest level of your home — an upper floor, not a roof with no exit. Do not use electrical appliances if you are standing in water. Listen to local radio or check the BOM website for live updates. Avoid driving unless absolutely necessary. news.com.au reports that thunderstorms can drop 40–60 millimetres in a few hours on already wet catchments, causing rapid creek rises. If you are caught outside, move to high ground immediately. Never shelter under a lone tree in a thunderstorm — lightning risk is real.
Recover Without Rushing After the Storm
Wait for official advice before returning to damaged buildings or flooded roads. Floodwater often contains sewage, chemicals, and debris. Wear rubber boots and gloves if you need to enter a flooded area. Take photos of damage for insurance claims. Beware of snakes that may seek shelter inside homes. If power is out, check for downed lines and report them. The second cold front mentioned by Nine.com.au can arrive just days after the first, so do not assume the danger has passed. Monitor BOM websites and local emergency services for the all-clear.
Severe storms are part of the Australian climate. Preparation, awareness, and calm action during the event make the difference between a wet few days and a disaster.
