Authorities will only ask you to leave your home if they have reason to believe you are in danger.
Evacuation alerts warn the public of a potential or current threat. These alerts provide critical information about an emergency and what you need to do. Alerts can lead to orders, so you should prepare to evacuate.
Evacuation orders are issued when the public must leave the area for their own safety.
Each emergency is different so there is no step-by-step guide that evacuations follow. If an evacuation alert is issued, you may have time to prepare your home for evacuation. If an evacuation order is issued, you will likely only have time to grab your emergency kit.
The below information is a guide; in an actual emergency, authorities will provide specific information and instructions.
