Final answer:
Before a tornado warning occurs, stay informed and be prepared with an emergency kit. If you're indoors during a tornado, seek shelter in a small, windowless interior room. If you're outdoors, find shelter in a sturdy building or a low-lying area.
Step-by-step explanation:
Before a tornado warning occurs, you should stay informed by listening to weather updates through a NOAA Weather Radio or a reliable news source. It is important to have a plan and be prepared with an emergency kit that includes non-perishable food, water, flashlights, and a first aid kit.
If you're indoors during a tornado, you should seek shelter in a small, windowless interior room on the lowest level of your home, such as a basement or a bathroom without windows. Cover yourself with a mattress or heavy blankets to protect against flying debris.
If you're outdoors during a tornado, you should immediately seek shelter in a sturdy building. If no shelter is available, find a low-lying area such as a ditch or a culvert and lie flat, covering your head with your hands. Stay away from trees and vehicles, which can be easily picked up and thrown by the tornado's strong winds.
