Frequently Asked Questions
What's the difference between a watch and a warning?
A Watch means conditions are favorable for severe weather to develop - you should prepare. A Warning means severe weather is occurring or imminent - you should take immediate action to protect yourself.
How do I receive weather warnings?
You can receive BOM warnings through the BOM website and app, Emergency Alert system (SMS to mobile phones), ABC radio, television news, and third-party weather apps. Enable notifications on your phone for the most timely alerts.
What should I do when a severe thunderstorm warning is issued?
Move indoors to a sturdy building, stay away from windows, unplug electrical appliances, avoid using corded phones, and if driving, pull over safely away from trees and power lines. Wait for the all-clear before resuming normal activities.
How accurate are weather warnings?
BOM warnings have high accuracy rates, especially for short-term severe weather. However, the exact location and intensity of severe weather can be difficult to predict precisely. Always err on the side of caution when warnings are issued.
Stay Prepared, Stay Safe
Weather warnings are your early alert system for dangerous conditions. By understanding what different warnings mean and having a plan in place, you can protect yourself, your family, and your property. Remember: when in doubt, take the safer option. Property can be replaced—lives cannot.
